About Navajovius
Navajovius is an extinct genus of plesiadapiforms that lived during the Paleocene epoch (66 to 56 million years ago). Plesiadapiforms were small, arboreal mammals that are theorized to be either closely related to primates or dermopterans. Navajovius has only been documented from localities within North America. This genus was officially named in 1921 by Walter Granger and William Matthew and the type specimen is housed at the American Museum of Natural History.
