Catopsalis
Catopsalis is a North American mammal genus from the Paleocene of North America, (though some Canadian finds may be Upper Cretaceous). This animal was a relatively large member of the extinct order of Multituberculata. (As a rough guide to size, I'm using the following highly specialized terms of my own concoction; heavyweight, super-heavyweight, sumo-heavyweight and sumo-super-heavyweight = up to 30kg.) Most multituberculates were much smaller.
Genus: Catopsalis Cope ED, 1882
Species: Catopsalis alexanderi Middleton MD, 1982
Species: Catopsalis calgariensis Russell LS, 1926
Species: Catopsalis collariensis
Species: Catopsalis fissidens Cope ED, 1884
Species: Catopsalis foliatus Cope ED, 1882
Species: Catopsalis joyneri Sloan RE & Van Valen L, 1965
Species: Catopsalis waddleae Buckley GA, 1995

Ref.
The genus was formally reported from the Upper Cretaceous of Mongolia. However, that material was subsequently referred to the genera of Djadochtatherium and Catopsbaatar.</b>
For those of a technical inclination, Catopsalis is within the Suborder of Cimolodonta, and a member of the superfamily Taeniolabidoidea.
Aka: Polymastodon (partly)
Place: Littleton Local Fauna, Colorado, Montana & Wyoming
Country: USA
Age: Puercan, Paleocene
Remarks: Some material of this genus was previously assigned to C. foliatus and C. joyneri. Specimens are included in the collections of the American Museum of Natural History[?], New York, and the Peabody Museum[?] of Yale. This species was a heavyweight for a multituberculate.
