Gurlin Tsav Skull
The "Gurlin Tsav" skull is a currently unnamed carnivorous metatherian fossil from the Nemegt Formation of Mongolia. Composed of a single semi-complete skull, this specimen is notable in regards to the evolution and systematics of Metatheria as a whole, and thus nigh-omnipresent in phylogenetic analyses of this group.S.

Fossil location The Gurlin Tsav skull, as the informal name indicates, comes from the Gurlin Tsav track in the Nemegt Formation. This area represents fluvial deposits, and also heralds a few dinosaur specimens, such as a ''Saurolophus'' skeleton.

Carnivorous
A carnivore , or meat-eater (Latin, ''caro'', genitive ''carnis'', meaning meat or "flesh" and ''vorare'' meaning "to devour"), is an animal or plant whose food and energy requirements derive from animal tissues (mainly muscle, fat and other soft tissues) whether through hunting or scavenging. Nomenclature Mammal order The technical term for mammals in the order Carnivora is ''carnivoran'', and they are so-named because most member species in the group have a carnivorous diet, but the similarity of the name of the order and the name of the diet causes confusion. Many but not all carnivorans are meat eaters; a few, such as the large and small cats (felidae) are ''obligate'' carnivores (see below). Other classes of carnivore are highly variable. The Ursids, for example: While the Arctic polar bear eats meat almost exclusively (more than 90% of its diet is meat), almost all other bear species are omnivorous, and one species, the giant panda, is nearly exclusively herbivorous. ...

Mayulestes
''Mayulestes'' (Quechua: ''mayu'' river, + Greek: ''lestes'', thief) is a genus of carnivorous metatherian that lived in what is now Tiupampa, Bolivia in the early Paleocene. It shared its habitat with fellow sparrasodont ''Pucadelphys'', and a microbiotherid marsupial, ''Khasia ''Khasia'' ("from Antin Khasa") is a fossil genus of marsupial in the family Microbiotheriidae. It contains one known species, ''Khasia cordillerensis'', which is known from teeth found in the Santa Lucia Formation of Mizque, Bolivia, where it ...''.

Alphadontidae
Alphadontidae was a family of mammals belonging to the clade Metatheria, the group of mammals that includes modern-day marsupials Marsupials are any members of the mammalian infraclass Marsupialia. All extant marsupials are endemic to Australasia, Wallacea and the Americas. A distinctive characteristic common to most of these species is that the young are carried in a po ....

Asiatherium
''Asiatherium'' is an extinct genus of mammal, probably belonging to Metatheria. It lived during the Late Cretaceous, and its fossilized remains were discovered in Mongolia. Description Skull of ''Asiatherium'' is in length. This animal was roughly the size of a mouse, and is known from a fairly complete articulated skeleton, preserving a complete skull. Its teeth resembled roughly those of marsupials; it possessed three premolars and four molars, and the mandible was slightly curved. Compared to ''Deltatheridium'', ''Asiatherium'' was even more marsupial-like, due to its molars having paraconids lower than the metaconids, and the paired entoconid-hypoconulid cusps on the lower molars. The stylar platform of the upper molars was however narrower and the stylar cusps weaker than in primitive marsupials. The upper molars differed from those of marsupials in their expanded praecingula and postcingula.*F. S. Szalay and B. A. Trofimov. 1996. The Mongolian Late Cretaceous Asiatheri ...
