The genus was found in and named after the Ischigualasto Formation (Cancha de Bochas Member) of the Ischigualasto-Villa Unión Basin in northwestern Argentina.

Paleoecology
It was a large quadrupedal herbivore, most common at the base of the Ischigualasto Formation. It was a common member of the local fauna, although not as abundant as the medium-sized herbivores Hyperodapedon and Exaeretodon.Script error: No such module "Unsubst". It was one of the two dicynodont that lived in the Ischigualasto Formation (the other being Jachaleria). The only danger to such a huge animal was the almost equally large carnivorous pseudosuchian Saurosuchus and perhaps the predatory dinosaur Herrerasaurus, which shared the same environment.Script error: No such module "Unsubst". Along with its relative Placerias, it was the second largest dicynodont after the gigantic Lisowicia.
