Afrotherians

Proboscideans

Proboscidean research

• Hauffe, Cantalapiedra & Silvestro (2024) present a Bayesian model that can be used to determine diversification dynamics from fossil occurrence data, apply it to the fossil record of proboscideans, and interpret their findings as indicating that the diversification of proboscideans was influenced by dietary flexibility and biogeography (particularly the association with islands), while the emergence of humans was the primary driver of proboscidean extinctions.
• Review of the evolution of the proboscidean head, focusing on the evolution of the anatomy and use of tusks and proboscis, is published by Nabavizadeh (2024).
• A study on the evolution of limb bones of extant and extinct proboscideans, providing evidence of adaptations to columnar posture and mass support, is published by Bader et al. (2024).
• Konidaris et al. (2024) describe new proboscidean material from Late Miocene localities in Romania, including fossils of Deinotherium proavum and "Mammut" cf. obliquelophus, as well as the first fossil material of a member of the genus Konobelodon from the country.
• Yaghoubi et al. (2024) describe fossil material of "Mammut" cf. obliquelophus from the Miocene fossiliferous areas of Maragheh (Iran), extending known geographical range of this taxon.
• May (2024) revises the biochronology and distribution of gomphothere occurrences from the Miocene of the Texas Coastal Plain.
• Evidence from the study of molars of Notiomastodon platensis from Brazilian Quaternary fossiliferous assemblages, interpreted as indicating that N. platensis was susceptible to tartar development, is presented by Paiva, Alves-Silva & Barbosa (2024).
• A study on the diet of specimens of Notiomastodon platensis collected from areas in central Chile is published by González-Guarda et al. (2024), who interpret their findings as indicative of the presence of xerophyte scrubs in central Chile during the Late Pleistocene, similar to the present-day environment of the studied area.
• Li et al. (2024) report the discovery of fossil material of Stegolophodon pseudolatidens from the Miocene Fotan Formation in Fujian, representing the first known record of Neogene proboscidean fossils in southeastern China.
• A study on the histology of a rib of a specimen of Stegodon florensis florensis from the So'a Basin (Flores, Indonesia) is published by Basilia et al. (2024), who interpret the histology of the bone tissue as possibly indicative of a relatively long lifespan of the studied individual.
• Biswas, Chang & Tsai (2024) provide body mass estimates of specimens of Palaeoloxodon from Taiwan, determining the studied specimens to be similar in size to straight-tusked elephants across Eurasia.
• Pineda et al. (2024) study the assemblage of straight-tusked elephant remains from the Notarchirico site (Italy), and argue that the available evidence does not supporth the interpretation of the studied site as the elephant butchery area.
• Jukar et al. (2024) describe a skull of a member of the genus Palaeoloxodon from the Middle Pleistocene Pampore Member in the Karewas of Kashmir, most closely resembling the skull of the type specimen of Palaeoloxodon turkmenicus, and interpret this finding as supporting the presence of a Middle Pleistocene species of Palaeoloxodon in Central and South Asia with a morphology intermediate between African and Eurasian species.
• Evidence from tooth enamel of a straight-tusked elephant specimen from the MIS 12 site Marathousa 1 (Greece), interpreted as indicating that the studied individual (as well as the hominins that processed its carcass) lived in stable environmental conditions with sufficient plant cover and limited seasonality, is presented by Roditi et al. (2024).
• A study on the age of the fossil, age and health of the individual prior to death, affinities and diagenetic processes after death of the mammoth specimen collected in 1966 from the hydrothermal spring deposit near Soda Springs (Idaho, United States), interpreted as one of the latest members of the Mammuthus jeffersonii lineage from the mainland Western North America reported to date, is published by Morrison et al. (2024).
• Rowe et al. (2024) use isotopic and genetic data from a tusk of a female woolly mammoth from the Swan Point Archaeological Site (Alaska, United States) to trace the studied individual's lifetime movements, interpret their findings as indicative of movement of the studied individual approximately 1000 km northwest in the middle of her life, and compare the range of movement of the studied mammoth with the distribution of early archaeological sites in Alaska, arguing that early North Americans likely settled in the territories frequently used by mammoths.
• Sandoval-Velasco et al. (2024) present evidence of preservation of three-dimensional genome architecture in a 52,000-year-old permafrost-preserved woolly mammoth skin sample collected near Belaya Gora (Sakha Republic, Russia).
• A study on the genetic consequences of isolation of woolly mammoths from Wrangel Island (Russia), as indicated by genomic data, is published by Dehasque et al. (2024), who find that the mainland population of mammoths from northeastern Siberia underwent little changes in genome-wide diversity prior to their extinction, that mammoths from Wrangel Island recovered quickly from the population bottleneck after becoming isolated on the island and their population subsequently remained stable with no evidence of accelerated decline prior to extinction (in spite of evidence of genomic erosion), and that the extinction of mammoths from Wrangel Island happened rapidly and its causes are uncertain.
• A review of the dwarf Sardinan mammoth species Mammuthus lamarmorai is presented by Palombo, Zedda and Zomboli (2024).
• Lister & Dalén (2024) evaluate the implications of the mammoth DNA analysis published by van der Valk et al. (2021) for the knowledge of the evolutionary history of mammoths and for their taxonomy.

• A study on the timeline and causes of extinction of Gigantopithecus blacki is published by Zhang et al. (2024), who use data from caves in the Chongzuo and Bubing Basin (China) to establish a regional window of extinction of G. blacki at 295.000–215.000 years ago, and interpret the demise of G. blacki as caused by inability to adapt to changes in forest structure resulting from increased seasonality.
• A sample of possible teeth of Pongo devosi is described from the Zhongshan Cave by Liang et al. (2024), representing fossil material of the smallest fossil orangutans from southern China reported to date.

• A study on the temporal lobe evolution in the family Hominidae, based on data from extant humans and great apes and fossil hominins, is published by Pearson & Polly (2024), who find that the greatest changes to temporal lobe proportions happened not in the genus Homo but earlier in hominin evolution.
• Ciurana et al. (2024) compare the muscle insertion sites on the proximal end of the ulna in extant and extinct hominids, interpret the relative size of the insertion sites as related to the relative mass of the triceps and the brachialis muscle and to the locomotion of the studied hominids, and interpret their findings as indicating that Australopithecus and Paranthropus likely used arboreal locomotion to complement their bipedalism, similar to extant bonobos but unlike members of the genus Homo.

• A study on the environmental preferences of hominins over the past 3 million years is published by Zeller & Timmermann (2024), who report evidence of two major phases of increasing adaptation toward rough terrain (related to greater biome diversity): from 2 to 1.1 million years ago, interrupted during the Mid-Pleistocene Transition, and from the 0.9 to 0.1 million years ago, coinciding with expansion of Homo heidelbergensis and Neanderthals into Europe.
• Claims that the Melka Kunture site-complex (Ethiopia) includes Oldowan and early Acheulean material which is approximately 2.0-1.9 million-years-old, presented by Mussi et al. (2023) and Muttoni et al. (2023), are contested by Gossa et al. (2024).
• Finestone et al. (2024) report the discovery of a new, approximately 1.7-million-years-old Oldowan locality Sare-Abururu (Homa Peninsula, Kenya), interpret the stone tools from this locality as indicating that hominins from Sare-Abururu were skilled knappers using quartz pebbles to produce flakes with sharp cutting edges, and report evidence of different raw material utilization and composition of stone tool assemblages from different Oldowan localities, likely related to differences of local landscapes and ecology.
• Evidence indicating that dental changes associated with later members of the genus Homo were not present in Homo habilis is presented by Davies et al. (2024).

(2024) determine the early hominin sites in the Orce region of Spain: Venta Micena, Barranco León-5 and Fuente Nueva-3 to be, respectively, approximately 1.32, 1.28 and 1.23 million years old, and interpret these dates as indicating that early hominins using Oldowan technology reached Europe approximately 0.5 million years after first leaving Africa.
• Despriée et al. (2024) determine the occupation of the Lunery-Rosieres la-Terre-des-Sablons site (France) by early hominins to date to around 1,175,000 years ago, and interpret the stone tool industries from this site and from other sites from Western Europe of similar age as indicating that early European hominins settled in zones that were only inhospitable during very cold stages, opportunistically flaked local siliceous materials and occasionally attempted complex core technologies.
• Ma et al. (2024) report evidence of the use of prepared-core technique at the Cenjiawan site in the Nihewan Basin (China), and interpret this finding as indicating that hominins with advanced technologies might have been present in high latitude East Asia as early as 1.1 million years ago.

• Kaifu et al. (2024) describe new hominin fossil material from the Mata Menge site (Flores, Indonesia), providing evidence that approximately 700,000 years ago hominins even smaller than the holotype of Homo floresiensis lived on Flores, and interpret H. floresiensis as member of a long-lasting lineage that likely evolved from Asian Homo erectus and maintained small body size during and beyond the Middle Pleistocene.

• A study on the morphological variation of the calvaria of Middle Pleistocene hominins from Africa and Eurasia with uncertain affinities is published by Hautavoine et al. (2024), who report that, in the general, the studied fossils from Africa tend to share closer affinities with Homo ergaster and Homo sapiens and the Eurasian specimens with Neanderthals, but also report that some of the studied specimens do not follow this general pattern, and interpret their findings as suggesting that multiple hominin populations with different affinities might have contributed to the emergence of Neanderthals and Homo sapiens.
• A study on the anatomy and affinities of Pleistocene hominins from the Xujiayao site is published by Wu & Bae (2024), who argue that Pleistocene hominins from Xujiayao and Lingjing sites in China might represent a previously unidentified population of large-brained hominins (subsequently assigned to the species Homo juluensis), differing from other Pleistocene hominins in cranial morphology and possibly resulting from interbreeding between different archaic human lineages.

(2024), who also describe a new Denisovan rib from the Baishiya Karst Cave, providing evidence of presence of Denisovans at the site until at least 48,000–32,000 years ago.
• Pablos & Arsuaga (2024) study the anatomy of tarsals, metatarsal bones and foot phalanges of Middle Pleistocene hominins from the Sima de los Huesos site (Spain), found to be generally more robust than corresponding bones of extant and fossil Homo sapiens, and interpret the anatomy of the studied bones as supporting the placement of the Sima de los Huesos hominins as the sister evolutionaty group of Neanderthals.
• Review of the anatomy of the thorax and lumbar spine of the hominins from the Sima de los Huesos site is published by Gómez-Olivencia & Arsuaga (2024).
• A study on wooden artifacts from Schöningen 13 II-4 (Germany) is published by Leder et al. (2024), who report evidence of the presence of at least 20 hunting weapons as well as evidence of the presence of artifacts which were likely domestic tools, indicating that Schöningen was not only a hunting or butchering site but also a place for domestic activities of the hominins that produced the artifacts.
• Evidence from the Schöningen 13II-4 site, interpreted as indicative of selective, specialized hunting of horses (Equus mosbachensis) by Middle Pleistocene hominins, is presented by Hutson et al. (2024).
• Riga et al. (2024) provide evidence of the presence of a hominin with a more archaic metatarsal morphology compared to Neanderthals at the Sedia del Diavolo site (Italy), which might indicate coexistence of at least two hominin clades in the Italian Peninsula during the beginning of Marine Isotope Stage 8.
• Evidence interpreted as indicating that Neanderthals had 2.5 to 3.7% modern human ancestry, as well as indicating that accounting for effects of modern human-introgressed DNA sequences results in reduction of estimates of Neanderthal population size by ~20%, and evidence of two distinct episodes of modern human gene flow into Neanderthal populations is presented by Li et al. (2024).
• A study on the frequency of enamel hypoplasia in Neanderthals and Upper Paleolithic anatomically modern humans is published by Limmer et al.

• Freitas-Oliveira, Lima-Ribeiro & Terribile (2024) argue that Thylacosmilus had a narrower climatic niche than Smilodon (and likely was more vulnerable to the climate change), and consider it unlikely that the extinction of Thylacosmilus was caused by competition with Smilodon.
• A study on the composition of the mammal faunas from the East African Rift System throughout the last 6 million years is published by Rowan et al. (2024), who report evidence of faunas largely composed of endemic species during the Late Miocene and Pliocene, and evidence of subsequent biotic homogenization likely related to regional expansion of grass-dominated ecosystems.
• Hanon et al. (2024) describe Plio-Pleistocene bovid material from the Kromdraai Unit P (South Africa), including fossil material of a previously unknown buffalo that could be closely related to Syncerus acoelotus and possible oldest fossils of members of the genera Damaliscus and Numidocapra (as well as Paranthropus robustus) in southern Africa, and interpret the studied bovids as indicative of a grassland-dominated environment; the authors also study other associations of bovid and hominin bones from Plio-Pleistocene South African sites, and find than members of the genus Australopithecus were associated with bovids adapted to woodlands and closed-wet environments and that members of the genus Homo were found with bovids adapted to open and dry environments, while members of the genus Paranthropus were found in association with bovids adapted to various environments.
• Sambo et al. (2024) study ecomorphology of bovids from the Kromdraai Unit P, interpret the studied bovids as living in a mosaic environment dominated by savanna grasslands, tall grasses and light bushes, with forests present to a lesser degree, and interpret their finding as indicative of presence of Paranthropus robustus in mosaic environmental settings.
• A study on the dietary guild structures of Pliocene herbivores from the Laetoli site (Tanzania) is published by Fillion & Harrison (2024), who argue that the replacement of Australopithecus afarensis by Paranthropus aethiopicus at the Laetoli site was related to an increase in grass cover within a woodland-grassland mosaic.

• Ramírez-Pedraza et al. (2024) report evidence from the Guefaït-4 fossil site (Morocco) indicative of the presence of a mosaic landscape with open grasslands, forested areas, wetlands and seasonal aridity close to the Pliocene-Pleistocene transition, which might have facilitated the dispersal of mammals (including hominins) from central or eastern Africa to northern Africa.
• A study on the structure of the Pleistocene large mammal assemblages from Eurasia, and on the factors that influenced their structure, is published by Bekeraitė, Juchnevičiūtė & Spiridonov (2024), who find that, in spite of environmental changes, the network of dependencies among mammalian clades present in the studied assemblages did not significantly change over time.
• A study on environments inhabited by early members of the genus Homo in Africa and Eurasia, as indicated by dental traits of mammals from these environments, is published by Foister et al. (2024), who interpret their findings as indicating that Early Pleistocene members of the genus Homo were able to occupy diverse environments, and that their expansion into Eurasia likely resulted in a niche expansion.
• A study on changes of ecospace occupancy of European carnivorans throughout the Pleistocene is published by Iannucci (2024), who finds that hominins entered Europe at the time when the continent lacked middle-sized carnivorans that were either highly social active hunters or primarily scavengers, and that hominins had the opportunity to fill a vacant ecospace at the time.
• Konidaris et al. (2024) review the late Early and Middle Pleistocene fossil record of mammals from the Megalopolis Basin (Greece), interpret the studied fossils as consistent with the refugial status of the basin for the studied mammals, and interpret the fossil record of hippopotamids from the Megalopolis Basin as likely indicative of body size decrease in response to changing climatic conditions.
• Zhang et al. (2024) report the discovery of fossil material of a new mammalian assemblage from the late Middle Pleistocene strata from the Upper Pubu Cave in the Bubing Basin (Guangxi, China), and interpret the composition of the studied assemblage as suggestive of environmental deterioration and reduction of the forested areas towards the end of the Middle Pleistocene.
• Fan et al. (2024) report the discovery of a new assemblage of mammals fossils from the late Middle Pleistocene strata from the Zhongshan Cave in the Bubing Basin (Guangxi, China), including diverse and abundant ruminants.
• A study on the fossil material of mammals from the Notarchirico site in southern Italy, providing evidence of subsequent appearances of three different mammal complexes in response of climatic-driven environmental changes, is published by Mecozzi et al. (2024).
• Espinasa-Pereña et al. (2024) report the discovery of a new assemblage of Pleistocene megafaunal fossils (including mammoths, gomphotheres, horses, deers, bovids, camelids, sloths, glyptodonts, felids, canids and lagomorphs) from the Calera cave system (San Luis Potosí, Mexico).

(2024) describe a new assemblage of mammal fossils from the Pleistocene site Cauca (Venezuela), including fossils of xenarthran megaherbivores, gomphotheres and equids, as well as fossil material of the ocelot or a related medium-sized feline, representing the first record of fossil material of cf. Leopardus pardalis in north-western Venezuela.
• A study on the carbon and oxygen isotope composition of remains of Eremotherium laurillardi, Notiomastodon platensis and Toxodon platensis from the Zabelê tank in the northeastern Brazil, providing evidence that the studied mammals lived in a transition zone between arboreal to open savanna and had a mixed-feeder diet with a higher consumption of C₄ plants compared to mammals from other Late Pleistocene localities in the Brazilian Intertropical Region, is published by Andrade, Dantas & Oliveira (2024).
• Evidence from the cave site of Grotta Grande (Salerno, Campania, Italy), interpreted as indicating that during the Marine Isotope Stage 5 the abandonment of the Neanderthal camp at the site was likely immediately followed by scavenging of remains left by Neanderthals by the spotted hyena, is presented by Spagnolo et al. (2024).
• A study on the ecology of prey species that Neanderthals depended on during the Late Pleistocene, as indicated by strontium isotope data from teeth from the Pech de l'Azé IV and Roc de Marsal sites (France), is published by Hodgkins et al. (2024), who find that the ranges of reindeers and bisons were restricted to the Aquitaine and Paris basins, where they were available year-round to the Neanderthal hunters, while horses and red deers had broader ranges and may have ventured into the mountainous regions.
• A study on the strontium isotope composition of remains of bovids and equids from Kenya living during the Last Glacial Period is published by O'Brien et al.

• A study on human prey selection criteria and on their impact on Pleistocene megafauna extinctions is published by Ben-Dor & Barkai (2024), who argue that limited protein metabolism capacity in humans led them to hunt prey (especially large-bodied taxa and prime adults) that were fat-rich but were more sensitive to hunting pressure than smaller prey.
• Bampi et al. (2024) review known record of megafauna kill sites in South America, interpreted it as robust as or even more robust in quantity and quality than North American records, and argue that limited scientific impact of the studies of the South American megafauna kill sites is mainly caused by language bias.
• Bradshaw et al. (2024) present stochastic models of megafauna population dynamics that can be used to study human impact on extinctions of megafauna, apply this model to the fossil record from the Late Pleistocene from Cyprus, and argue that the estimated human population sizes after the human arrival on the island were sufficient to drive Palaeoloxodon cypriotes and the Cypriot pygmy hippopotamus to extinction within less than 1000 years.
• Evidence interpreted as indicative of a relationship between critical periods of seasonality and desertification and late Quaternary megafauna extinctions in continental regions and connected islands, as well as indicative of a relationship between critical periods of climate change and modern human arrival in continental regions, is presented by Graipel et al.
