In the absence of a comprehensive fossil record, origin and early evolution Malagasy lemurs have been subject to much uncertainty. We report here discovery strepsirrhine with strong cheirogaleid lemur affinities, Bugtilemur mathesoni gen. et sp. nov., from Oligocene deposits Bugti Hills (Balochistan, Pakistan). represents earliest record Lemuriformes, which hence appear already diversified outside Madagascar at least 30 million years ago. This clearly enhances critical role Indian...
Rhinocerotids are particularly abundant and diversified in Neogene deposits of the Indian subcontinent, but their systematics is far from being well defined. Based on revision old collections new findings Early Miocene Bugti Hills Zinda Pir, Pakistan, 'Aceratherium blanfordi Lydekker, 1884' a chimera, consisting two dentally convergent postcranially distinct rhinocerotid taxa: Pleuroceros Mesaceratherium welcommi sp. nov. Postcranial features appear to be much more diagnostic than...
The Paleocene-Eocene Thermal Maximum (PETM) is correlated with the first occurrences of earliest modern mammals in Northern Hemisphere. latest Paleocene Clarkforkian North American Land Mammal Age, that has yielded rodents and carnivorans, only exception to this rule. However, until now no pre-PETM localities have Europe or Asia. We report equivalent Age deposits basal Sparnacian facies at Rivecourt, north-central part Paris Basin. new terrestrial vertebrate macroflora assemblages are...
In the southwestern Sulaiman geological province (Balochistan, Pakistan), terrestrial detrital facies from Bugti Hills region have yielded richest Tertiary vertebrate faunas to be found in Asia thus far. New fossils five successive and distinct ‘bone beds’ bridge supposed Oligocene sedimentary hiatus within province; lowermost continental levels of previously described Miocene Chitarwata Formation, known as Member, are age area. Neither a mixture heterochronic faunal elements nor endemism...
The living Laotian rodent Laonastes aenigmamus, first described in early 2005, has been interpreted as the sole member of new family Laonastidae on basis its distinctive morphology and apparent phylogenetic isolation from other rodents. Here we show that is actually a surviving otherwise extinct Diatomyidae, known Oligocene to late Miocene sites Pakistan, India, Thailand, China, Japan. particularly striking example "Lazarus effect" Recent mammals, whereby taxon was formerly thought be...
Today, the continental ecosystems of Southeast Asia represent a global biodiversity hotspot. From deep-time perspective, however, very little is known about formation this In particular, evolutionary and biogeographic roots numerous terrestrial biota are unknown, ecosystemic information, especially for Paleogene, unavailable. The Na Duong Basin in northern Vietnam has yielded remarkable diversity Paleogene vertebrate, invertebrate, plant fossils, thus one few localities allowing...
Abstract Deer are an iconic group of large mammals that originated in the Early Miocene Eurasia (ca. 19 Ma). While there is some consensus on key relationships among their members, basis molecular- or morphology-based analyses, combined approaches, many questions remain, and bony labyrinth has shown considerable potential for phylogenetics this other groups. Here we examine its shape 29 species living fossil deer using 3D geometric morphometrics cladistics. We clarify several issues origin...
The Eocene-Oligocene Transition (EOT; ~34 Ma) is one of the most significant climate shifts Cenozoic era, representing transition from last warmhouse state to a coolhouse state. EOT had impact on terrestrial ecosystems and was synchronous with "Grande Coupure", major episode faunal turnover in western Europe associated influx multiple clades Asian tetrapods. displays considerable regional variability sedimentary records, its role opening dispersal corridors for Grande Coupure remains...
Asian tarsiid and sivaladapid primates maintained relictual distributions in southern Asia long after the extirpation of their close Holarctic relatives near Eocene–Oligocene boundary. We report here discovery amphipithecid eosimiid from Oligocene coastal deposits Pakistan that demonstrate stem anthropoids also survived beyond climatic deterioration characterized transition. These fossils provide data on temporal paleobiogeographic aspects early anthropoid evolution significantly expand...
Abstract Extrinsic and intrinsic factors impact diversity. On deep-time scales, the extrinsic of climate geology are crucial, but poorly understood. Here, we use inner ear morphology ruminant artiodactyls to test for a correlation between low adaptive anatomical structure both variables. We apply geometric morphometric analyses in phylogenetic frame X-ray computed tomographic data from 191 species. Contrasting results across clades show that neutral evolutionary processes over time may...
A new tragulid, Archaeotragulus krabiensis , gen. n. et sp. n., is described from the late Eocene Krabi Basin (south Thailand). It represents oldest occurrence of family which was previously unknown prior to Miocene. displays a mixture primitive and derived characters, together with M structure on trigonid, appears be main dental autapomorphy family. We also report at Lophiomerycid, Krabimeryx primitivus affinities Chinese representatives family, particularly Lophiomeryx . The familial...
We report the discovery of remains a large chelonian from base early Paleocene Khadro Formation exposed in Ranikot Fort area (Ranikot Group, Sindh Province, Southern Pakistan). This formation already yielded snake Gigantophis Andrews, 1901, studied by our friend Jean-Claude Rage. The specimens consist carapace and shell fragment Bothremydidae, family Gondwanan origin. A new genus species, Sindhochelys ragei n. gen., sp. is identified first specimen named honor It Bothremydidae Pakistan. Its...
Abstract Debate persists concerning the timing and geodynamics of intercontinental collision, style syncollisional deformation, development topography fold‐and‐thrust belts along >1,700‐km‐long İzmir‐Ankara‐Erzincan suture zone (İAESZ) in Turkey. Resolving this debate is a necessary precursor to evaluating integrity convergent margin models kinematic, topographic, biogeographic reconstructions Mediterranean domain. Geodynamic argue either for synchronous or diachronous collision during...
Island biotas have disproportionately influenced the history and development of evolutionary biology, but understanding their genesis evolution across geological timescales has been hindered by a poor fossil record. Here we augment insular Eocene (~43 Ma) mammalian fauna known from Pontide terrane central Anatolia describing two new metatherian taxa (stem marsupials) Lülük Member Uzunçarşıdere Formation in Orhaniye Basin. Geological paleontological data indicate that was an island on...
ABSTRACT Deer (Cervidae) have a long evolutionary history dating back to the Early Miocene, around 19 million years ago. The best known fossils document this belong European taxa, which all bear cranial appendages more or less similar today's deer antlers. Despite good fossil record, relationships of earliest stem and crown are much debated. This hampers precise calibration against independent evidence record in molecular clock analyses. While has been written on Middle Miocene deer, only...
