Ameribaatar is an extinct mammal of the Late 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 unclear. The genus Ameribaatar ("American hero") was named by Eaton and Cifelli in 2001.
Temporal range: Late Cretaceous
