This study reports occurrences of feliform carnivorans from the Upper Eocene Ergilin Dzo Formation and Alag Tsav locality of southeastern Mongolia. Nimravus mongoliensis (Nimravidae) is distinguished from other species in having a deep mandible, a longer p/1–2 and m/2 relative to p/4, and relatively wider P3/. Eofelis sp. (Nimravidae), a genus previously known only from the Oligocene of France is found in the Ergilin Dzo Formation. Alagtsavbaatar indigenus comb. nov. (Alagtsavbaatar gen. nov… 

How Many Sabertooths? Reevaluating the Number of Carnivoran Sabertooth Lineages with Total-Evidence Bayesian Techniques and a Novel Origin of the Miocene Nimravidae

Some of the most extreme sabertooth adaptations are found within the carnivoran subfamily Barbourofelina, the largest group of carnivorous mammals in the world.

First nimravid skull from Asia

The new taxon, based on a complete cranium from the middle-upper Eocene Youganwo Formation of Maoming Basin, Guangdong Province, China, suggests origin and initial diversification of Nimravidae in Asia and proposes that this group dispersed to North America in the late Eocene and to Europe in the early Oligocene.

Discovery of a crocodyliform tooth from the upper Eocene Ergilin Dzo Formation, Mongolia

Although the distribution of Asian crocodyliforms was extended northwards during the Paleocene–Eocene greenhouse world, the fossil record in northern Asia becomes scarce towards the end of the

In Mongolia, fossil mammals are known from the Upper Jurassic, Lower and Upper Cretaceous, all series of the Paleogene and Neogene, as well as the Pleistocene. Over 335 new species and more than 185



New Amphicyonid (Mammalia: Carnivora) from the Upper Eocene Ergilin Dzo Formation, Mongolia

Abstract. A mammal tooth discovered from the upper Eocene Ergilin Dzo Formation of southeastern Mongolia is identified as an upper second molar of a small amphicyonid (Mammalia: Carnivora). It is

The Entelodontid Artiodactyl Fauna from the Eocene Ergilin Dzo Formation of Mongolia with Comments on Brachyhyops and the Khoer Dzan Locality

Abstract. We review the entelodontid artiodactyl fauna of the upper Eocene Ergilin Dzo Formation in southeastern Mongolia. Also, we describe new specimens of Brachyhyops trofimovi from the Khoer Dzan

New Avian Remains from the Eocene of Mongolia and the Phylogenetic Position of the Eogruidae (Aves, Gruoidea)

A well-preserved nearly complete avian tarsometatarsus collected by the 2002 expedition of the Mongolian Academy of Sciences is identified as part of a proposed Eogruidae clade, although it is unclear whether it is appropriately the holotype of a new species within this clade or referable to a previously named species.

The genus Stenoplesictis Filhol (Mammalia, Carnivora) from the Oligocene deposits of the Phosphorites of Quercy, France

The discovery of new remains assigned to Stenoplesictis (Feliformia, Carnivora) in the deposit of Quercy (France) allows a more precise study of this genus, which may be a primitive feloid like the extant Nandinia binotata.

A preliminary report on carnivorous mammals from Pondaung fauna

This report intends to introduce carnivorous mammal materials discovered from the Pondaung Formation in the recent expeditions and to provide more detailed information on the specimens.

7. The carnivore guild of the Taatsiin Gol area: Hyaenodontidae (Creodonta), Carnivora, and Didymoconida from the Oligocene of Central Mongolia

New specimens of hyaenodontid creodonts, carnivorans, and didymoconids were unearthed in Mongolia by the Austrian-Mongolian Paleontological Expeditions and provide insight into the distribution, migration and paleobiology in the Oligocene of Asia.


We describe a new bunodont anthracothere(Mammalia;Artiodactyla),Myaingtherium kenyapotamoides sp.nov.,discovered from the upper middle Eocene Pondaung Formation of Myanmar.The specimens

Hyaenodon chunkhtensis and The Hyaenodontid Fauna From The Upper Eocene Ergilin Dzo Formation Of Mongolia

Hyaenodon Laizer and Parieu, 1838 is one of the most speciose genera of the Hyaenodontidae (Mammalia; Creodonta) and is widely distributed in the late middle Eocene to Oligocene of North America

Middle Eocene ungulate mammals from Myanmar: a review with description of new specimens

The estimated paleoecologies of the included taxa, the geologic and geographic evidence, and cenogram analysis suggest that the paleoenvironment of the Pondaung fauna was forested/woodland vegetation with humid/sub− humid moisture and large rivers, which were located not far from the eastern Tethyan Sea.
