Twelve confirmed deaths following Magnitude 5.8 Earthquake in Afghanistan.

The United States Geological Survey recorded a Magnitude 5.8 Earthquake at a depth of 186.4 km, roughly 35 km to the south of the town of Jurm in Badakhshan Province, northern Afghanistan, slightly after 8.40 pm local time (slightly after 4.10 pm GMT on Friday 3 April 2026. The Earthquake was felt across Afghanistan, as well as southern Tajikistan, northern Pakistan, and India as far as New Delhi. 

Twelve people have been confirmed to have been killed by the event, eight of them members of the same family who died when their house collapsed in the Gosfand Dara area of Kabul province, according to the Afghan Red Crescent Society. The only member of the family reported to have survived the collapse was a two-year-old boy, who is said to have been badly injured. The remaining four people killed were in separate incidents to the east of Kabul. Another three people have been reported to have been injured, with five houses destroyed and 33 damaged, affecting 40 families across  Kabul, Panjshir, Logar, Nangarhar, Laghman and Nuristan provinces. This pattern of causing little damage close to the epicentre but more harm in an area a considerable distance from the epicentre is typical of deep Earthquakes, the energy of which is dispersed over a wide distance before reaching the surface.

The boundary between the Indian and Eurasian tectonic plates runs close to northern Afghanistan. The Indian Plate is moving northward relative to the Eurasian Plate, causing folding and uplift along this boundary, which has led to the formation of the Hindu Kush Mountains of Afghanistan, the Himalayas and the other mountain ranges of Central Asia., and which makes the nations in this boundary zone prone to Earthquakes.

While the occurrence of Earthquakes in Afghanistan is inevitable, the situation is made far worse by the country's weak infrastructure, with few buildings having any form of Earthquake-proofing. Homes are typically made from concrete and brick in urban areas, and wood and mud brick in rural areas, with little in the way of building regulations, and neither material help nor advice available to people who might want to invest in improving the resilience of their properties. Previous natural disasters in Afghanistan have seen many people displaced internally by the loss of both homes and infrastructure as well as shortages of drinkable water, and local hospitals and medical centres struggling to cope due to shortages of medicines, equipment, and staff (in particular female staff, most of whom have been forced to leave their occupations due to the restrictive laws of the Taliban regime).

Marine Trematosaurid Temnospondyls from the Early Triassic of Western Australia.

The Temnospondyls were an ancient group of Tetrapods, which are the sister group to the modern Lisamphibians (Frogs, Salamanders, and Caecilians), although they were in many ways more Reptile-like, with many apparently able to live completely away from water for much of their lives, while others colonised marine environments. The first Temnospondyls appeared in the Carboniferous, rapidly expanding to become one of the most diverse and abundant groups of terrestrial Vertebrates. The Temnospondyls remained a major group throughout the Permian and Triassic, but were badly affected by the End Triassic extinction from which they never recovered. A few Temnospondyl lineages persisted through the Jurassic and into the Early Cretaceous, when they finally disappeared.

The Trematosaurids were a group of Temnospondyls which migrated into marine environments in the Early Triassic, evolving to occupy a large marine predator role which had become vacant during the End Permian Extinction, and spreading throughout much of the world's environments. Trematosaurids have been described from Madagascar, Greenland, Australia, Pakistan, Spitsbergen, European Russia, the Russian Far East, Germany, and Jordan. 

To date, only a single species of Marine Trematosaurid (several others are known from clearly non-marine environments) has been described from Australia, Erythrobatrachus noonkanbahensis, which described in 1972 by John Cosgriff and Neil Garbutt on the basis of a composite of fragmentary cranial remains from the Early Triassic Blina Shale of the central-southern Kimberley region of far northwestern Western Australia, collected during a series of expeditions to the area in the 1960s.

The Blina Shale records a transgressive delta setting (setting where the land is extending into the sea over a delta system), which would have faced onto the East Gondwana interior rift seaway. These deposits record a mixture of saline, brackish, and freshwater environments, and have produced non-Trematosaurid Temnospondyls such as the Rhytidosteid, Deltasaurus kimberleyensis, the Capitosauroid, Warrenisuchus aliciae, and the Brachyopids, Batrachosuchus henwoodi, and Banksiops townrowi. A variety of other fossils have also been found within the Blida Shale, including the ubiquitous Triassic Saurichthyid Actinopterygian, Saurichthys, a variety of Ceolacanths, the Ptychoceratodontid Lungfish, Ptychoceratodus philippsi, the Sagenodontid Lungfish, Aphelodus anapes, the Ceratodontid Lungfish, Asiatoceratodus tiguidensis, several possible Sharks, Conodonts, Insects, Spinicaudatans and Lingulid Brachiopods, possible Pseudomonotid Bivalves, indeterminate Ammonoids, some possible Mollusc egg cases, burrow traces, palynomorphs (fossil pollen and spores), Achritarchs, Horsetails, and possible Lycopods. 

Temnospondyls from the Blina Shale are typically found in a disarticulated state, either as individual bones or accumulations, and show signs of having been transported before their final deposition, including weathering and sorting by size. This is consistent with deposition in beds with preserved ripple marks and thin cross-lamination, which is suggestive of a shallow, tidal environment. 

In a paper published in the Journal of Vertebrate Palaeontology on 22 February 2026, Benjamin Kear of the Department of Palaeobiology at the Swedish Museum of Natural History, Nicolás Campione of the Palaeoscience Research Centre at the University of New EnglandMikael Siversson of the Western Australian Museum, and the School of Molecular and Life Sciences at Curtin UniversityMohamad Bazzi of the Department of Earth and Planetary Sciences at Stanford University, and Lachlan Hart of the School of Education and Earth and Sustainability Science Research Centre at the University of New South Wales, as well as the Australian Museum Research Institute, reassess that material assigned to Erythrobatrachus noonkanbahensis from the Blinda Shale deposits, and draw new conclusions about the presents of Trematosaurid Temnospondyls in the Early Triassic of Western Australia.

The original material assigned to Erythrobatrachus noonkanbahensis included the holotype, WAM 62.1.46, two topotype specimens, WAM 71.6.22 and WAM 62.1.50, and a high-definition plaster caste of the holotype, WAM 62.1.59 (in taxonomy, a holotype is the specimen from which a species is described, any other specimen considered to belong to the same species as the holotype therefore belongs to that described species, but if the holotype is found to belong to the same species as the previously described holotype of another species, then the newer species is considered invalid; a topotype is a specimen asigned to a species which comes from the same location as the holotype). All of these specimens were placed in the collection of the Western Australian Museum, but when Kear et al. came to look for them, only WAM 62.1.50 and WAM 62.1.59 could be found, WAM 62.1.46 and WAM 71.6.22 having apparently been loaned to John Cosgriff in 1984, at which time he was working at Wayne State University in Detroit, Michigan. 

A search of the palaeontological collection of Wayne State University could not locate these specimens, although WAM 62.1.46 was subsequently found in a search for potentially related specimens in the collection of the University of California Museum of Paleontology, where it had been identified as cf. Tertrema sp., and given the identifier UCMP 65858. The collection of the University of California Museum of Paleontology was also found to contain a second high-definition plaster caste of this specimen, listed as UCMP 65850. The University of California Museum of Paleontology has subsequenty returned WAM 62.1.46 to the Western Australian Museum. 

Also found within the collection of the University of California Museum of Paleontology was a box labelled WAM 62.1.50, however, this was found to be empty, having been 'withdrawn for study' by John Cosgriff in August 1968.

Specimen WAM 62.1.46, the holotype of Erythrobatrachus noonkanbahensis is a steinkern internal cast from the naso-frontal region of the skull and vomero-palatine section of the palate. This, along with the plaster casts WAM 62.1.59 and UCMP 65850, show Erythrobatrachus noonkanbahensis to have had an elongate skull with a basally constricted rostrum, dorsolaterally facing orbits that are positioned close to the lateral jaw margin, broad nasals that contact the lacrimals posterolaterally, and possibly the septo-maxilla near the external bony nasal opening, anteriorly narrow interpterygoid vacuities that are bordered by transversely broad palatines, ctopterygoids apparently lacking large palatal tusks, at least at the ectopterygoid-palatine suture, and a narrow cultriform process of the parasphenoid that divides the interpterygoid vacuities along the palatal midline, and extends to a point level with the anterior edges of the choanae.

Scale bars equal 50 mm. Kear et al. (2026).

Specimen WAM 62.1.50 is an external impression of the vomerine palate showing multiple dental rows and anterior margins of the choanae. This is recorded as a paratype of Erythrobatrachus noonkanbahensis on its Western Australia Museum label (a paratype is a specimen other than the holotype of a species which is used in the formal description of that species), but as 'cf. Aphaneramma' (refer to Aphaneramma) on the label of the empty box at the University of California Museum of Paleontology, a label which Kear et al. assume reflects Cosgriff's original thoughts on the classification of the specimen. Aphaneramma is a cosmopolitan Trematosaurid Temnospondyl also known from the Early Triassic of Pakistan, Madagascar, Russia, and Svarlbard. 

WAM 62.1.50 appears to be similar in proportions to the skull of Aphaneramma gavialimimus, a large (skull-lenght about 400 mm) species of Aphaneramma described from Madagascar in 2017. It also has fine longitudinal bone ridges, which have previously been observed in members of the genera AphanerammaWantzosaurus, and Cosgriffius. The choanae of WAM 62.1.50 are longitudinally offset, such that the left opening would have been displaced anteriorly relative to the right, something which has also been recorded in other specimens of Aphaneramma. In their 1972 description of Erythrobatrachus noonkanbahensis, Cosgriff and Garbutt identify this as being the result of displacement of the right choanae, which they believe was 'compressed and pushed forward from its original position', but which Kear et al. consider may be a diagnostic feature of the genus. Notably, WAM 62.1.50 shows several rows of vomerine teeth (teeth on the roof of the mouth), which are absent in WAM 62.1.46, suggesting the two do not belong to the same species. Vonerine teeth are found in Aphaneramma, as well as some other genera of Trematosaurid Temnospondyls, although the size and arrangement of those of WAM 62.1.50 do not appear to exactly match any previously described taxa. For this reason, Kear et al. return WAM 62.1.50 to the designation cf. Aphaneramma

Cosgriff and Garbutt apparently viewed the additional specimens assigned to Erythrobatrachus noonkanbahensis, WAM 71.6.22 and WAM 62.1.50, as developmental stages of the species, noting that they were smaller than the holotype, WAM 62.1.46. As WAM 71.6.22 could not be located, this assessment could not be evaluated for this specimen, but Kear et al.'s study clearly shows that the smaller size of WAM 62.1.50 only relates to its fragmentary nature, and that it was clearly derived from quite a large animal. Furthermore, it differs significantly in morphology to WAM 62.1.46, and cannot be assigned to the same species.

This expands the diversity of Temnospondyls known from the Blina Shale, and expands our knowledge of how that assemblage relates to wider Temnospondyl faunal distributions in the Early Triassic. This includes widespread Australian species such as Deltasaurus kimberleyensis, Warrenisuchus aliciae, and Banksiops townrowi, taxa also known from South Africa, such as the genus Batrachosuchus, species not found anywhere else, such as Erythrobatrachus noonkanbahensis, and now an example of the globally distributed genus Aphaneramma. This also increases the distribution of these marine Temnospondyls, raising the possibility that their distribution was not just due to expansion along the continuous coastal Tethyan periphery of the Pangean supercontinent, but may also have involved longer distance, ocean-crossing dispersals between Laurasia and Gondwana across the Tethys Ocean.

Comet C/2026 A1 (MAPS) approaches perihelion.

Comet C/2026 A1 (MAPS) will reach its perihelion (the closest point on its orbit to the Sun) on Saturday 4 April 2026, when it will be approximately 0.006 AU from the Sun (i.e. 0.6% of the distance from the Sun to the planet Earth, which is about 852 700 km, or a little over twice the distance between the Earth and the Moon). At this time the comet will be 1.05 AU from the Earth, in the constellation of Pisces, but it will not be visible due to its extreme closeness to the Sun.

Should the comet survive this close encounter (which is not guaranteed), then it will reach apogee (the closest point on its orbit to the Earth) two days later, on 6 April 2026. At this point it will be 0.96 AU from us (i.e. 96% of the distance between the Earth and the Sun, or 143 614 000 km), still in the constellation of Pisces and still not visible. 

Comet C/2026 A1 (MAPS) was discovered on 13 January 2026 by the 0.28 m f/2.2 Schmidt telescope at the AMACS1 Observatory at San Pedro de Atacama. The name C/2026 A1 implies that it is a comet (C/) that it was discovered in the first two weeks of 2026 (period 2026 A), and that it was the first comet discovered in this period (1). The designation (MAPS) derives from the initials of the team which discovered it, Alain Maury, Georges Attard, Daniel Parrott, and Florian Signoret.

Comet C/2026 A1 (MAPS) is calculated to have an orbital period of 1900 years and a highly eccentric orbit tilted at an angle of 149° to the plain of the Solar System, or 59° to the plain of the Solar System but orbiting in a retrograde direction, the opposite direction to the planets and the majority of smaller bodies. This orbit brings it to 0.006 AU from the Sun at closest perihelion (0.6% of the distance between the Earth and the Sun) and out to 307 AU from the Sun at aphelion (307 times as far from the Sun as the Earth or about 10 times as far from the Sun as the planet Neptune, and considerably outside the Kuiper Belt). As a comet with a period of more than 200 years, C/2026 A1 (MAPS) is considered to be a non-Periodic Comet, since it is unlikely that it would be identified as the same body on another visit to the Inner Solar System. As a comet which comes within 0.01 AU of the Sun, C/2026 A1 (MAPS) is also considered to be a Kreutz Sungrazer Comet.

The Kreutz Sungrazer Comets, a group named after the nineteenth century German astronomer Heinrich Kreutz, have been shown to share a number of other properties, notably an orbital inclination which tends to be close to 144° relative to the plain of the Solar System, and an orbit which takes them to beyond 100 AU from the Sun. In 1967 the British astronomer Brian Marsden calculated that these comets could be subdivided into two groups, which clustered around the orbits of Comet Ikeya–Seki (which visited the Inner Solar System in 1965), and the 'Great Comet' of 1882. 

From this he calculated that these comets were all remnants of a single large comet, which had first broken into two halves during a close encounter with the Sun, then smaller pieces with each subsequent pass. He further calculated that the orbit of Ikeya–Seki appeared to be very similar to that of the 'Great Comet' of 1106, which was documented by observers across Europe, North Africa, and East Asia, and suggested that this might have been the parent body for the whole family. Subsequent researchers have suggested that there are more subgroups within this family, and that the Great Comet of 1106 was itself a fragment of an earlier body, which some of the other subgroups are derived separately from.

Calculations based upon the initial observations of C/2026 A1 (MAPS) led to the conclusion that the nucleus of this comet was about 2.4 km in diameter. However, subsequent observations by the James Webb Space Telescope have led to the conclusion that it is much smaller at about 400 m in diameter. This makes it one of the smallest known comets, as well as the first Kreutz Sungrazer to have had its nucleus directly measured, giving scientists a particular interest in whether it will survive its close encounter with the Sun.

A cremation from the Early Holocene of Malawi.

All modern Human societies feel the need to dispose of the dead in specific, often highly ritualised, ways, and this appears to have been the case for much of the history of our species, and potentially other members of the genus Homo. Cremation is an effective way to achieve this, transforming the recognisable remains of a member of the community into a small amount of ash and calcined bone fragments in a relatively short period of time. However, this process also requires the effort and co-ordination to build a funeral pyre of sufficient size, and does not appear to have become common or widespread until the Middle Holocene.

The oldest known assemblage of burned Human remains comes from Lake Mungo in New South Wales and have been dated to about 40 000 years before the present, although these remains appear to have gone through a multi-stage ritual process which included burning, rather than being a single cremation event as the main way to deal with the remains. The oldest evidence of a body being burned on a pyre comes from a site called Xaasaa Na′ (Upward Sun River) in the Alaskan Arctic, where a child of about three years, who was burned about 11 500 years ago. The oldest known burned remains in Africa are about 7500 years old and come from Egypt, but it is unclear whether these were deliberately cremated. The oldest known evidence for deliberate cremation in Africa comes from Njoro River Cave in Kenya, and is only about 3300 years old.

In a paper published in the journal Science Advances on 1 January 2026, a team of scientists led by Jessica Cerezo-Román of the Department of Anthropology at the University of Oklahoma present evidence for a deliberate cremation, from the Hora 1 archaeological site at the foot of Mount Hora in the Mzimba District of Northern Malawi.

Mount Hora is a 110 m high granite inselberg (isolated hill) rising above the Kasitu River Valley, which forms a distinctive regional landmark. The Hora 1 archaeological site is a rock shelter at the base of this hill, opening to the east and incorporating a flat dry area of about 80 m². This site is easily accessed from all directions, and contains no enclosed areas which could act as a natural furnace. No other natural rock shelters could be found in the region. Hora 1 has produced a record of Human occupation stretching over more than 21 000 years, and appears to have been used for mortuary practices between about 16 000 years ago and about 8000 years ago.

HOR-1 site (11°39′S, 33°39′E; 1470 m above mean sea level, white stipples) relative to published excavated Later Stone Age (LSA) sites. Light green in inset outlines the Zambezian Biome. Cluster of sites near Mpunzi (or Mphunzi) Mountain includes six additional sites, three with human remains (Mtuzi, Changoni Bible School, and Chencherere II). Cerezo-Román et al. (2026).

This site was first excavated by Desmond Clark and William Rangeley in the 1950s, who excavated an area of 7-8 m² (Clark and Rangeley did not record measurements of the area they excavated, but did take photographs, which have been used to reconstruct the extent of their work). These excavations produced the almost complete remains of two adult Humans, HOR-1 (or UTC-242), a male directly dated to between 9081 and 8725 years before the present, and Hora 2 (or UTC-243), a female directly dated to between 8172 and 7875 years before the present. Both of these skeletons have yielded ancient DNA, suggesting a relationship to modern hunter-gatherer populations in Southern Africa.

Between 2016 and 2019, the Malawi Ancient Lifeways and Peoples Project carried out further excavations at the site, removing and sieving 7.8 m³ of sediment from two blocks which produced about 46 500 objects, including the almost incomplete skeletons of two male infants (Kahora 1 and Kahora 2), which have been indirectly dated (i.e. dated from material found with them, not directly from the skeletal material) to about 14 000 and about 16 000 years before the present, and which have also yielded ancient DNA, as well as fragmentary remains attributed to at least four additional adults (Hora 4 to Hora 7) and five additional non-adults (Kahora 2 to Kahora 3), as well as numerous animal remains. Examination of these fragmentary remains has suggested that they may have been subjected to complex mortuary practices, including secondary burials (i.e. burials either after being buried once and then excavated, or after having been either left unburied for an extensive period, or having been subjected to ritual behaviours which substantially altered the remains), which may have included ritual token-taking.

(2026).

Cerezo-Román et al. report the discovery of a large ash feature at Hora 1, along with an associated set of remains attributed to a single cremated adult, who they designate as Hora 3. Hora 3 is calculated to have been chronologically intermediate between Hora 2 and Kahora 1. As such it appears to form part of a genetically continuous population which lived in the area across the Pleistocene-Holocene boundary, although (unsurprisingly) it was not possible to extract DNA from the cremated remains.

The 'ash feature' forms a large cemented block, dated to about 9500 years before the present, which overlies a Pleistocene sediment sequence which begins 17 000 years ago and ends about 12 000 years ago, and is overlain by younger Early Holocene deposits. At the core of this feature they found a set of Human remains identified as 'Cluster 1), which lie on top of an ash layer 10-15 cm thick, and roughly 2.5 m by 1.5 m in extent. Below this are a series of deeper lenses of consolidated ashes, charcoal, and rubified sediment, together referred to as the 'Lower Ash', which are interpreted as evidence for a series of consecutive burn events at the same location.

The Cluster 1 remains sit on top of a layer of incompletely combusted charcoal, and are in turn overlain by several more stratified lenses of ash and rubified sediment. A second set of remains was identified to the northeast of Cluster 1 and 5-10 cm deeper. These were identified as Cluster 2, but appear to be a part of the same individual which became detached during the cremation event.

Plan view of the exposed ash complex, showing the large spatial extent. Jessica Thompson in Cerezo-Román et al. (2026).

Twenty radiocarbon dates were obtained from the core pyre and larger ash feature, providing a chronology for the site. Dates obtained below the core feature begin around 12 699 years before the present, with the latest coming from 9918 years before the present. Layers of ash above the core feature produced dates ranging from 9540 to 9454 years before the present, while a layer of ash on the eastern excavation wall was dated to between 9538 and 9455 years before the present. A Land Snail bead from a layer immediately above the core combustion event provided a date of between 9537 and 9441 years before the present, and is taken as evidence of this layer being covered over quickly by non-combustion sediments. Another large combustion event was indicated by a stratigraphically higher layer of ash, which produced a date of between 9452 and 9142 years before the present, i.e. less than 400 years after the core event, although this layer produced no Human remains. Above this were further layers of non-combustion deposits dating from between less than 9403 and 9031 years before the present.

Phytoliths are produced by plants as a way of handling silica absorbed with water from the soil. Most plants produce phytoliths to some extent, but Monocotyledons, such as Grasses and Palms, which utilise phytoliths both as structural support and a defence against herbivores (silica phytoliths quickly wear down the teeth of animals which lack specific adaptations to deal with them), produce phytoliths which can often be used to identify the maker to genus or even species level. Phytoliths recovered from the Hora 1 pyre deposits imply that the majority of the ash was generated by the burning of wood, but that non-woody plant fibres were also present. 

Sediments and ash layers of the pyre deposit. (A) view southwest of the feature 50 cm south of Cluster 1 of the remains. In both (A) and (B) black arrows indicate the top of micromorphology sample MALAPP 834 and white arrows show the distal radius from Cluster 1 in situ. Dashed box is the profile in (C), which shows layered ash with flecks of charcoal overlying rubified sediment. Distinct root and termite disturbances are visible crossing the boundaries of the intact ash layers. The brownish (grey when dry) sediment above and below is also ash-rich but more mixed (homogenised) and darker due to a higher content of finely comminuted organic material and microcharcoal. The sediments were dampened with a mist of water prior to taking the photos and image levels were adjusted to emphasise colour differences. Jessica Thompson in Cerezo-Román et al. (2026).

These pyre deposits comprise a series of laminated ash layers extending horizontally for more than a metre, and containing ash, charcoal, rubified sediments, and Human remains. These deposits have been penetrated by insect burrows and/or plant root tunnels in places, presumably before the ash layers became cemented. Examination of the rubified sediments suggests that these contain fragments of baked clay which probably originated from structures built on trees by termites, suggesting that deadwood was collected to build the pyre(s). Also present were carbonised fragments of the Bracket Fungus Ganoderma.

Thin section of sample 834. Sample 834 was collected from the pyre, about 1m away from the Hora 3 remains (A). One thin section was selected from the small block sample (B) with reddish disturbed sediments in the lower part, and bright ashes in the top (C). Termite galleries and shelter tubes are very common in woodland areas, especially on deadwood, which presents ready-for-use fuel and was likely preferentially selected to build the pyre (D); (E) displays the clear boundary between compact laminated ashes (lower half of photomicrograph) and mixed ashy sediment on top, which are mixed with sandy clay soil aggregates.

The ash deposits generally contain fewer artefacts (such as flakes from toolmaking) than non-ash deposits, probably relating to the fact that these were laid down much more rapidly. However, the Human-remains-containing core layer contains many more such objects, suggesting that they were deliberately included within the pyre, possibly for symbolic reasons.

A total of 170 Human bone fragments were recovered from the pyre area. Of these, 112 could be clearly identified as specific parts of the Human skeleton, with the remaining 18 identified as 'likely human' on the basis of their size, texture, and preservation. The majority of these bone fragments (160) were recovered within the ash feature, with 152 found within the core feature. Of the elements which could definitely be identified as Human, 97 could be assigned to a specific element, with 90 of these being long bone (i.e. arm or leg) fragments. Other fragments from the core pyre include partial left and right calcanei, an unsided patella, the lower right articular facet of a lumbar vertebra, and four phalanges. All are consistent with a single individual.

Analysis of the Hora 3 skeleton suggests that this individual was a female aged between 18 and 60. The individual is presumed to be an adult on the basis that it appears to be skeletally mature, with the distal femur and radius having fused. The articular margin of the distal femoral epiphysis showed marginal lipping, which may indicate the presence of a mild degenerative disease, giving the upper age estimate. No other potential age-markers were preserved. Since it was impossible to recover DNA from the burned and fragmented remains, sex was estimated using overall small size and gracility and the vertical diameter of both preserved femoral heads. On the basis of the diameter of the femora, the individual is estimated to have been between 145 and 150 cm tall in life (about 5 feet). Based upon the maximum and minimum midshaft diameters of the right humerus and femur, Hora 3 it thought to have been less mobile than most modern Southern African hunter gatherers, and more accustomed to manual labour.

About 585 g of material thought to be derived from the skeleton of Hora 3 was recovered. This is notably less than is typically produced by a Human cremation, which is usually more than 1500 g. Notably, no head elements were found within the core pyre area, although a fragment of a sphenoid (the base of the skull) was found within the larger ash feature. Fragments of cranium, and in particular teeth, are usually among the most easily preserved and identified elements in cremations, and it is surprising not to have found any such fragments, given that sediment and ash removed from the site were wet sieved to 1 mm.

All of the skeletal remains show transverse, curved-transverse, and longitudinal cracks, which are typical for the burning of a fleshed corpse, but none show signs of the checking pattern fractures which are often seen when dry remains are burned. Most fragments were grey to black, with some brown, bluish-white, and white hues. Fragments from closest to the torso were typically the most blackened and charred, while more distal elements were grey or white - which indicates more exposure to flame in areas which would have been covered by less flesh. Many elements are white on their external surface, while internal surfaces are grey, which implies these elements were intact when the burning occurred. These colours suggest that the temperature to which the distal elements were exposed exceeded 500°C, while elements closer to the torso typically reached maximum temperatures lower than 500°C. Fourier-transform infrared spectroscopy is sensitive to low temperature heating of bone, which often does not involve recrystallisation, and therefore can provide an accurate palaeothermometer for low temperature cremations. Four white/grey fragments from Hora 3 were analysed in this way, with all producing spectral peaks indicative of heating to over 500°C.

Although the body of Hora 3 shows signs of having been manipulated after the cremation, many of the recovered fragments were recovered together, covered in ash, and in some cases cemented together. This includes a right distal humerus and right proximal radius cemented together along with long bone fragments and a possible metacarpal fragment. This appears to show that intact joints were present at the time of final disposal of the remains. Many of the bone surfaces are covered by calcium carbonate, with none of the recovered Human bones showing more than 50% exposure. Nevertheless, eight of the bones showed stone tool marks consistent with defleshing, while none showed any signs of having been scavenged by carnivores.

Cerezo-Román et al. reconstruct a sequence of events in which people began using the HOR-1 as a habitation site about 21 000 years ago. The earliest recorded burials at the site occurred 16 000 and 14 000 years ago, both being infants. Small ash features consistent with campfires appear around the end of the Pleistocene, with larger pyres appearing by 10 240 years before the present.

Some time between 9540 and 9454, a pyre comprising at least 30 kg of deadwood and grass, with some hairy leaves from herbaceous plants, was assembled, something which would have represented a significant investment of time and effort by the local community. The body of a small, probably female, adult individual was then burned on this pyre, probably within a few days of their death. The distribution of the bones, particularly those of the arms and legs, suggests that this individual was placed on this pyre in a flexed or pugilistic position (i.e. with the knees and elbows brought in close to the torso). Cut marks on some of the bones show signs of defleshing, although the preservation of the bones and some joints suggests that the flesh of the body (or some other covering) was present at the time of burning. It is likely that the skull was removed before the burning, since neither scavengers nor Early Holocene hunter gatherers seem likely to have been able to remove all of the fragments which would have been produced by burning a skull, while leaving other elements of the skeleton in situ. The ritual removal of skulls, and other body parts, has been documented in a range of modern African populations, but never at a site of such antiquity.

The fire achieved was able to reach temperatures above 500°C, although this doesn't appear to have been consistent, and the lamination of the deposits suggests that the fire-makers continued to add fuel to the pyre for some time. The detachment of Cluster 2 from Cluster 1, and the greater degree of burning seen on Cluster 1, may indicate that the body was manipulated during the cremation process to detach parts of it. Knapped material appears to have been added to the pyre, either at the outset or during the process, possibly in association with other funerary objects. Multiple further fires were lit at the same site over the next few hundred years, although no further cremations appear to have occurred.

Evidence of cremation among African hunter-gatherer populations is extremely rare in the archaeological record, and has not previously been found south of the Sahara. The oldest previously documented example come from the Nabta Playa site in southern Egypt, where a single individual appears to have been burned between 7800 and 7300 years ago (i.e. at least 1300 years before the earliest date for the Nabta Playa stone circle), and this has been interpreted as a 'burned inhumation' rather than a true cremation, possibly caused by the accidental ignition of material placed within the grave. Burned Human remains, possibly as much as 7000 years old, have also been recovered from an ancient midden near Lake Besaka in Ethiopia, although again this does not represent an in situ pyre like that seen at Hora, and again may not represent an intentional burning. The previous oldest known intentional cremations from Africa are associated with Neolithic Elmenteitan pastoralists in Kenya, about 3300 years ago.

A open-air, pyre cremation such as that seen at Hora requires a significant investment in time and labour by the local population, which may be why the practice is so rare among hunter-gatherer populations. In an enclosed furnace, a Human corpse can be burned in about two hours, but open air cremations require considerably longer, during which time the temperature must be maintained, typically by adding more fuel. Nevertheless, such a cremation would be a notable community event, particularly if, as seems to have been the case at Hora, parts of the body were removed during the process for ritual disposal elsewhere.

While the Hora site only records a single event, which seems to have been highly unusual in nature, it adds to a growing picture of a culturally diverse tropical African hunter-gatherer population in the Early Holocene, displacing an earlier impression that these peoples were likely to have been culturally homogeneous, even over great distances and long periods of time. The people at Hora did not erect megaliths or other architectural features. Nevertheless, they appear to have utilised chosen a site of natural prominence to carry out a significant mortuary ritual, a site which appears to have been utilised repeatedly over an extended period of time (at least 16 000 years), albeit with changing rituals during that time.

Evidence for evolving social cooperation and complexity has been recorded from many ancient hunter-gatherer populations around the world, although until now this has largely been absent from Africa. The Hora Rockshelter in Northern Malawi records a population showing both a diversity of behaviour and the ability to stage large events which would have required the investment of time and effort by many individuals. This appears to have been carried over multiple generations, with repeated fires being lit, including at least one subsequent major pyre event, suggesting a communal memory in which the significance of the location was maintained over many generations.

Cerezo-Román et al. conclude that around 9500 years ago the remains of an adult female were burned on a substantial pyre at the Hora Rocksheter in Northern Malawi. This is the oldest known pyre cremation in Africa, and the oldest known adult pyre cremation in the world. The fire appears to have been one of a sequence of fires at the same location, which persisted for centuries after the cremation event, signifying the importance of the site to the population. This site demonstrates the emergence of complex funerary rights, communal projects involving large numbers of people, and the recognition of certain sites as culturally significant long before the emergence of agriculture and organised food production, challenging previous conceptions about the extent to which community co-operation occurred among ancient hunter-gatherer populations in tropical Africa.
