Ameribaatar Ameribaatar is an extinct mammal of the middle Cretaceous. It was a member of the also extinct order of Multituberculata. It lived in North America during the Mesozoic, also known as the "age of the dinosaurs". Whether it belongs to Plagiaulacida, Cimolodonta, or neither, is presently unclear. The genus Ameribaatar ("American hero") was named by Eaton and Cifelli in 2001. The primary sspecies, Ameribaatar zofiae, was also named by Eaton and Cifelli. Its fossil remains were discovered in strata dating to the Albian-Cenomanian (Lower-Upper Cretaceous) boundary in the Cedar Mountain Formation, Utah (USA). The species name honours Zofia Kielan-Jaworowska. References - Eaton & Cifelli (2001), Multituberculate mammals from near the Early-Late Cretaceous boundary, Cedar Mountain Formation, Utah.
