Rodent-like, they first appeared in the Middle Jurassic, and became extinct in the early Oligocene. They are named for their teeth, which had many... Multituberculata. Representatives are known from the Upper The Cretaceous period is one of the major divisions of the geologic timescale, reaching from the end of the Jurassic period (about 135 mya) to the beginning of the Paleocene epoch of the Tertiary period (65 mya).

Cretaceous and the The Paleocene epoch (64-58 mya) (early dawn of the recent) is the first geologic epoch of the Tertiary period in the modern Cenozoic era.

The family Cimolomyidae was named by Othniel Charles Marsh ( October 29, 1831 - March 18, 1899) was one of the pre-eminent paleontologists of the 19th century, who discovered and named many fossils found in the American West. Marsh was born in Lockport, New York. He graduated at Yale College in 1860, and studied geology and mineralogy... Othniel Marsh in 1889.
