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
TLDR
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
TLDR
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

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