Eobaatar

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.

Eobaatar hispanicus
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
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 Khoboor beds in Guchin Us County, Mongolia.

Eobaatar minor
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.

Eobaatar pajaronensis
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.

E. clemensi
E. clemensi is a species described in 2009 by Steven C. Sweetman in the open-access journal Acta Palaeontologica Polonica. the fossil remains date back to the Barremianstage of the Early Cretaceous, and were uncovered in the Wessex Formation of the Isle of Wight, part of the Wealden Group. The remains were first discovered in the early 1970s. The specific epithet honors Professor William A. Clemens who worked on mammals of the Wealden Supergroup of south−east England. It is based on BMNH M 45482 and paratype BMNH M 45557 tooth crowns. Part of SMNS 51981, a poorly preserved left tooth crown, and BMNH M 45483, a well preserved left tooth crown and partial root, are tentatively ascribed to this species. The holotype was discovered in bed L9 exposed about 300 m north−west of Grange Chine on the south−west coast of the Isle of Wight.
