Arginbaatar

Arginbaatar was a Lower Cretaceous mammal from Mongolia. It was a member of Multituberculata, an order which is also extinct.

Genus: Arginbaatar Trofimov BA, 1980

Family: Arginbaataridae Hahn & Hahn, 1983

Species: Arginbaatar dimitrievae Trofimov BA, 1980
Place:
Country: Mongolia
Age: Aptian or ALbian, Lower Cretaceous
Remarks: This genus is the only known member of its family, which is thus monotypic. Some characteristics are "Plagiaulacida"-like, whilst others are more akin to the further derived suborder of Cimolodonta. Quite where it fits in is unclear. "This family shows a mixture of 'plagiaulacidan' and cimolodontan characters, (Kielan-Jaworowska & Hurum, 2001, p.415).
