Catopsalis is a genus of mammal from the Paleocene of North AmericaNorth America is the third largest continent in area and the fourth ranked in population. It is bounded on the north by the Arctic Ocean, on the east by the North Atlantic Ocean, on the south by the Caribbean Sea, and on the west by the North Pacific Ocea, (though some Canadian finds may be upper CretaceousThe 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). The end of the Cretaceous also defines the). This animal was a relatively large member of the extinct order of Multituberculata. Most multituberculates were much smaller.
The genus was formally reported from the upper Cretaceous of MongoliaAlternative meaning: Mongolia (region Mongolia ( Khalkha Mongolian: is a landlocked country in Asia, bordered by Russia to the north and the People's Republic of China to the south. After the conquest of China by the Mongol Empire, much of Mongolia was ru.
