Serows and gorals (Bovidae, Caprinae) are emblematic antelopes distributed in Southeast Asia. They all are nearly threaten or vulnerable species nowadays despite having a more widespread distribution during the Pleistocene. Fossils of three native caprine species, i.e., a Sumatran serow Capricornis sumatraensis, Chinese goral Naemorhedus griseus, a...

The evolutionary history and palaeoecology of orangutans remains poorly understood until today. The restricted geographic distribution of extant Pongo indicates specific ecological needs. However, it is not clear whether these needs were shared by the great diversity of fossil pongines known from the Miocene to the Pleistocene. Here we show how nic...

The diversity of basal ungulates is significant in the late middle Eocene Pondaung Formation (Myanmar). However, the precise identification or attribution of some fossils is sometimes difficult because of the scarcity and poor preservation of the material. We describe here a new genus and species of a Dichobunidae from Paukkaung Kyitchaung 2 locali...
Article
Tham Wiman Nakin or “Snake Cave” has so far been recognized as being the only late Middle Pleistocene Homo-bearing fauna, dated to older than 169 ka, in mainland Southeast Asia. Since the last two decades, the highly diversified mammal fauna found from this cave has been widely used as standard references for several studies, though the majority of...
Article
We describe several mammal taxa from the poorly known late Eocene locality of Bang Mark, Krabi Basin in southern Thailand. Most of them were unknown in that locality that now includes 19 distinct taxa. The new material corresponds to dental remains that can be attributed to a carnivoran, a dichobunid, ruminants, anthracotheres and perissodactyls. T...
Article
Parapithecines are an extinct subfamily of stem anthropoid primates previously known only from the Jebel Qatrani Formation in Egypt. Here, we describe isolated teeth pertaining to Simonsius harujensis sp. nov., a relatively small-bodied parapithecine from strata near Zallah Oasis in the Sirt Basin of central Libya that is estimated to date to ∼31 M...
Article
The study and reanalysis of late Oligocene and middle Miocene dental material from Thailand provides evidence for long-distance stratigraphic correlations, and thus sheds new light on past terrestrial connections between Southeastern Asia and Europe. Here we report the oldest occurrence of Ursidae in southern Asia – a late Oligocene fossil from Non...
Article
Full-text available
Since their discovery in 1927, the phylogenetic status of the Myanmar amphipithecines has been highly debated. These fossil primates are recognized either as anthropoids or as adapiform strepsirrhines. This uncertainty was largely the consequence of a limited fossil record consisting mostly of jaw fragments but lacking the critical cranial elements...
Conference Paper
At least four genera of unusually large Eocene bats are currently known from Europe and North Africa. Large bats belonging to the extinct family Philisidae are known from the middle Eocene of Algeria, Egypt, and Tunisia. We report an upper first molar belonging to a new species of the philisid Witwatia from the middle Eocene Dur At-Talah escarpment...
Article
The Galericinae are a group of Erinaceidae that are currently distributed in Southeast and Eastern Asia. Although galericines have an Asian origin, their fossil record in this region is scarce, which greatly limits the knowledge of the evolutionary history of this group. We describe here the first fossils of Eulipotyphla from the middle Miocene (13...
Article
Carnivoraformes is a clade comprised of members of the Carnivora, as well as the paraphyletic assemblage of stem taxa previously united under the "Miacidae". Here we describe the earliest known African occurrence of a carnivoraform from the early Oligocene Zallah Incision locality in the Sirt Basin of central Libya. The new taxon is represented by...
Article
Full-text available
The late middle Miocene fossil-bearing lignite zones of the Mae Moh Basin, northern Thailand, have yielded a rich vertebrate fauna, including two species of Carnivora described thus far: the bunodont otter Siamogale thailandica (known from over a 100 specimens) and the large amphicyonid Maemohcyon potisati. Here we describe additional carnivoran ma...

Three taxa within the subfamily Caprinae (Himalayan goral Naemorhedus goral, Chinese goral Naemorhedus griseus, and Sumatran serow Capricornis sumatraensis) live in the mountainous upland forests of Southeast Asia, where they are considered as vulnerable or near threatened species. Co-occurrences between these two recognized genera have been docume...
Article
Two new genera and species of small basal ruminants are described from the middle Eocene Pondaung Formation in Myanmar. One form, Paukkaungmeryx minutus, gen. et sp. nov., is attributed to a primitive Archaeomerycidae, and the other, Stenomeryx bahinensis, gen. et sp. nov., very likely represents the oldest known Tragulidae, a family unknown in Pon...
Article
Full-text available
Sivaladapidae is a poorly known Asian strepsirrhine family originally discovered in Miocene sediments of the indian subcontinent. Subsequent research has considerably increased the diversity, temporal range, and geographical distribution of this group, now documented from china, thailand, Myanmar, pakistan, and india and whose earliest representati...

We report here the first direct dating study of the faunal assemblage from Khok Sung locality, Thailand. This palaeontological site is of great biochronological, palaeoenvironmental and biogeographical significance. Firstly, it has yielded a rich and diversified Pleistocene vertebrate fauna with up to 15 mammalian species from 13 genera, 10 reptile...
Article
The evolutionary history of Asian Miocene hominids (great apes and humans) remains poorly documented, obscuring the ancestry of orangutan (Pongo). Khoratpithecus from the middle and late Miocene of Thailand and Myanmar was previously documented only by mandibles and isolated teeth. It has been interpreted as the closest relative of Pongo based on s...
Article
Full-text available
Recent discoveries of older and phylogenetically more primitive basal anthropoids in China and Myanmar, the eosimiiforms, support the hypothesis that Asia was the place of origins of anthropoids, rather than Africa. Similar taxa of eosimiiforms have been discovered in the late middle Eocene of Myanmar and North Africa, reflecting a colonization eve...
Conference Paper
During the Cenozoic, Myanmar has been a key area for mammalian evolution, this region having seen the emergence and diversification of several major groups of eutherian mammals such as anthropoid primates as well as ruminant and hippopotamoid cetartiodactyls. While a very rich mammalian diversity has been described from this region, very few studie...
Article
Full-text available
A well-preserved astragalus of the anomaluroid rodent Pondaungimys anomaluropsis is described from the late middle Eocene Pondaung Formation of central Myanmar. This specimen is the first postcranial element of a rodent from the Pondaung Formation and the oldest postcranial fossil currently known for Anomaluroidea. It illuminates plesiomorphous pos...
Article
Full-text available
We describe two entelodontid upper premolars that were recovered from the late Eocene of the Krabi coal mine in southern Thailand. The size and morphology of the material suggest that it can be referred to Entelodon aff. E. gobiensis, a species known from the late Eocene to the early Oligocene of northern Asia and southern China. The Thai material...
Article
Paleoecological and paleoclimatic records based on the stable isotopes of mammalian tooth enamel are poorly known in mainland Southeast Asia during the Pleistocene. Khok Sung in Northeastern Thailand is a late Middle Pleistocene terrace deposit, tentatively dated either as 213 ka or 188 ka, yielding 15 described mammalian taxa with especially abund...
Presentation
The area of Magway (Central Basin of Myanmar) has yielded in 2011 a late Miocene fauna comprising the hominoid primate Khoratpithecus, a Pongo relative. Here we present new data collected by the Myanmar-French Paleontological Expedition further documenting the biodiversity of this fauna. This assemblage comprises the equid Hipparion s.l., the probo...

TORTONIAN RODENT SITES FROM LACUNAL AND TRANSITIONAL MARINE DEPOSITS IN ORAN AREA: MARINE CONTINENTAL CALIBRATION Evidence of new micromammal sites from lagunal (Tafna, Feid EI Atteuch) and transitional marine (Sig 1, Sig 2) deposits associated with planktonic foraminifera suggest a Vallesian (Tortonian) age. The marine continental correlation give...
Article
The middle Eocene Pondaung Formation in Myanmar has yielded a rich mammalian fauna including several Primate taxa. Hyaenodonta are known by the genera Kyawdawia, Yarshea, Orienspterodon, and two other indeterminate taxa. We describe here new material of Kyawdawia, including some morphological details, a new species of the hypercarnivorous genus Pro...
Chapter
The Asian origins theory suggests that the origin and the earliest evolutionary steps of anthropoid primates occurred in Asia, rather than in Africa as previously believed. In such a model, the earliest anthropoid primates would have dispersed from Asia to Africa during several events that occurred between 45 and 34 million years ago. This would ex...
Article
Full-text available
We describe an exceptionally well preserved skull of a small anthracothere from the late middle Eocene of the Pondaung Formation that can be confidently attributed to Siamotherium pondaungensis, a species that was first diagnosed on the basis of a fragmentary maxilla preserving two upper molars. The new material confirms that Siamotherium pondaunge...

Résumé L’évolution de l’homme s’inscrit dans la durée, comme celle de la plupart des autres mammifères. Les premiers primates anthropoïdes, les plus anciens représentants de sa lignée, proviennent d’Asie et remontent à 45 millions d’années. Au cours de cette longue évolution, deux stades se sont révélés très importants : leurs débuts et l’émergence...

Seggeurius is the basal-most hyracoid known to date, and one of the earliest known fossil afrotherians. This taxon has a dramatic importance in mammalian phylogeny, but until now it was known from dental remains only. Here we describe previously unpublished material of Seggeurius, including some mandibular and maxillary fragments, and a braincase....
Article
Strain resulting from the collision of India with Asia has caused fundamental changes to Asian drainage patterns, but the timing and nature of these changes are poorly understood. One frequently proposed hypothesis involves the connection of the palaeo Tsangpo drainage to a precursor to the Irrawaddy River of central Myanmar in the Palaeogene. To t...
