Eobataar (lapsus calami)

Eobaatar is a genus of extinct mammal from the Lower Cretaceous of Mongolia, Spain and England. A member of the also extinct order Multituberculata, 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. Its name was made from Greek "eos" = "dawn" and Mongolian "baatar" = "hero"", "warrior".

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 the Camarillas Formation, 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 Dzunbain Formation 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 Dzunbain Formation 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 the Camarillas Formation in Spain.

Eobaatar clemensi

[edit]

This species was named by Steven Sweetman in 2009. Remains were found in the Barremian (lower Cretaceous) of the Wessex formation, England.
