Mammalia - Multituberculata - Cimolodontidae

Taxonomy
Cimolodon nitidus was named by Marsh (1889). Its type specimen is YPM 11776, a tooth (M1), and it is a 3D body fossil. Its type locality is Mammal Quarry No. 1 (UCMP V-5003), which is in a Lancian terrestrial horizon in the Lance Formation of Wyoming. It is the type species of Cimolodon.

It was recombined as Cimolomys nitidus by Hay (1902); it was synonymized subjectively with Cimolomys gracilis by Simpson (1929).
