Liotomus
Liotomus is a mammal genus from the Paleocene of Europe and North America, and thus lived just after "the age of the dinosaurs." It was a member of the extinct order of Multituberculata, lying within the suborder Cimolodonta and possibly the family Cimolodontidae. Genus: Liotomus (Cope ED, 1884)
Aka: Neoctenacodon Lemoine, 1891; Neoplagiaulax (partly); Parectypodus (partly). This genus is sometimes placed within Eucosmodontidae (Jepsen, 1940). Species: Liotomus marshi (Lemoine, 1882) Cope ED, 1884
Aka: Neoctenacodon marshi; Neoplagiaulax marshi
Known from the Upper Paleocene of Cernay, France. Has been cited as a descendant of Anconodon gidleyi. Species: Liotomus vanvaleni
Aka: Parectypodus vanvaleni (Sloan RE, 1981)
Age: Puercan, Lower Paleocene
Place: San Juan Basin, New Mexico Liotomus sinclairi, which also seems to have been known as Ptilodus sinclairi, has probably since become Parectypodus sinclairi. References - Cope (1884), "The Tertiary Marsupialia." American Naturalist, 18, p.686-697.
