Chasicotherium
Extinct genus of notoungulates
From Wikipedia, the free encyclopedia
Chasicotherium is an extinct genus of a large notoungulate mammal known originally from a partial skull and mandible discovered in the Arroyo Chasicó Formation, in the stream of Party of Villarino, Buenos Aires, Argentina. The sediments in which the animal was discovered dates to 10 to 9 million years (Chasicoan). It is known only from the 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 large herbivore of the Miocene Pampas, closely related to Homalodotherium, which also shares the reduced dental formula of the short premaxilla.[2]
