''Dakotamys'' is a Genus of extinct Mammal that lived during the Upper Cretaceous . It shared the world with Dinosaur s. This small creature was a member of the also extinct order Multituberculata within the suborder Cimolodonta and was a member of the Paracimexomys Group . The genus ''Dakotamys'' ("Dakota mouse") was named by Eaton J.G. in 1995. Dakota refers to the Dakota Formation. It's a geological term rather than a geographical one. "'' Paracimexomys '' and ''Dakotamys''... resemble the Eobaataridae in the structure of the upper and lower molars, with cusps showing a tendency to coalesce, and with ornamentation of grooves and ribs on the molars," (Kielan-Jaworowska & Hurum, 2001, p.403). Species: ''Dakotamys malcomi'' Eaton JG, 1995 Place: Cenomanian (Upper Cretaceous)-age Strata of the Dakota Formation, Utah . This species would have weighed perhaps 25 g. The type specimen is in Oklahoma . Some material from Utah has subsequently been reassigned to a different genus, ''Cedaromys'' (Eaton & Cifelli 2001.). "''Dakotamys''" Tedrow & Korth, 1997 was a description of fossil Rodents , which were subsequently renamed ''Dakotallomys''. These two species, ''D. lillegraveni'' and ''D. pelycomyoides'', really are from the south of the Dakota Formation, but are obviously not multituberculates. REFERENCES
