About Anconodon
Anconodon is an extinct genus of mammal from the Paleocene of North America, and thus lived just after the "age of the dinosaurs". It was a member of the extinct order Multituberculata within the suborder Cimolodonta and possibly the family Cimolodontidae.
The genus Anconodon was named by G. L. Jepsen in 1940. It is also known as Ectopodon (Russell 1967); Ectypodus (partly); Liotomus (partly); and Ptilodus (partly).
