Liotomus is a mammal genus from the Paleocene of Europe and North America, and thus lived just after ‘the age of the dinosaur's. It was a member of the extinct order of Multituberculata.
For those of a technical inclination, it's within the suborder of Cimolodonta, and possibly the family Cimolodontidae.
Genus: Liotomus Cope ED, 1884
Aka: Neoctenacodon Lemoine, 1891; Neoplagiaulax (partly); Parectypodus (partly)
Remarks: This genus is sometimes placed within Eucosmodontidae Jepsen, 1940.

Further remarks: Liotomus sinclairi, (which also seems to have been known as Ptilodus sinclairi), has probably since become Parectypodus sinclairi.
