---------

Zofiabaatar is a genus of extinct mammal from the Upper Jurassic period. It was a relatively early member of the extinct order Multituberculata within the suborder "Plagiaulacida". It lived in North America along with dinosaurs such as Diplodocus and Allosaurus.

The primary species is named Zofiabaatar pulcher. Fossils have been found in the Upper Jurassic Morrison Formation of Wyoming (U.S.). The animal was reportedly about 30 cm long. It seems to have been a rather specialized creature, judging by the dentary, which is all that's known. Zofiabaataridae are believed to belong to the allodontid line.

Present in stratigraphic zone 6.[1]
