Chasicotherium is an extinct genus of a large notoungulate mammal known originally from a partial skull with mandible discovered in the Chasico Formation, in the stream of the same name of the Party of Villarino, Province of Buenos Aires, Argentina. The sediments in which the animal remains were discovered have an antiquity between 10 and 9 million years (Chasicoan). It is known only from its type species, C. rothi. Its weight was approximately 1 tonne (0.98 long tons; 1.1 short tons), being the largest and most recent member of the family Homalodotheriidae. It was a great herbivore of the Miocene Pampas, closely related with Homalodotherium, with it shares the reduced dental formula and the short premaxilla.[2]
