Eobaatar is a genus of extinct mammal from the Lower Cretaceous of Mongolia and Spain. It was a member of the also extinct order Multituberculata, and lived at the same time as some dinosaurs. It lies within the suborder Plagiaulacida and family Eobaataridae. The genus Eobaatar was named by Kielan-Jaworowska Z., Dashzeveg D. and Trofimov B.A. in 1987.

Species[edit]

Eobaatar hispanicus[edit]

This species was named by Hahn G. and Hahn R. in 1992. Remains consisting of a single tooth were found in Hauterivian - Barremian (Lower Cretaceous)-age strata of Galve, Spain.

Eobaatar magnus[edit]

This species was named by Kielan-Jaworowska Z., Dashzeveg D. and Trofimov B.A. in 1987. It is based on a fragment of lower jaw with teeth found in Aptian or Albian (Lower Cretaceous) strata of the Höövör beds in Guchin Us County, Mongolia, and had a cranial length of about 3 cm.

Eobaatar minor[edit]

This species was also named by Kielan-Jaworowska Z., Dashzeveg D. and Trofimov B.A. in 1987. Remains were found in Lower Cretaceous strata of Mongolia. Going by the species name, it was probably relatively small; his skull was 2 cm in length indeed.

Eobaatar pajaronensis[edit]

This species was named by Hahn G. and Hahn R. in 2001. Remains were discovered in Barremian (Lower Cretaceous) strata of Ple pajaron in Spain.
