The sediments in which the animal remains were discovered date to 10 to 9 million years (Chasicoan). It is known only from its type species, C. rothi. Its weight was approximately {{convert|1|t}}, 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] References1. ^Cabrera, A. y Kraglievich, L. 1931.
