binomial_authority = Hahn G. & Hahn R.,1998 "Proalbionbaatar" is a small
mammal from the UpperJurassic ofGuimarota ,Portugal . It's the most derived member of the orderMultituberculata known from that locality, and shared the world with the much largerdinosaur s. It lies within the suborder "Plagiaulacida " and familyAlbionbaataridae .The genus "Proalbionbaatar" was named by Hahn G. and Hahn R. in 1998, based on a single species. The name refers to it being both earlier and more basal than "
Albionbaatar ", a broadly similar form known from the LowerCretaceous ofDorset ,England .The species "Proalbionbaatar plagiocyrtus" was named by Hahn G. and Hahn R. in 1998.
Fossil remains are known from theKimmeridgian (Upper Jurassic)-age strata of Guimarota, Portugal. Remains are presently restricted to two isolated upper molars, which are smaller than the corresponding teeth of paulchoffatiids (Paulchoffatiidae is the best represented multi group from Guimarota). These teeth also have more cusps, which are arranged in two rows. (Hahn & Hahn 2000, p.106).References
