The big cats could return to do the job they once did in Brazil's grassland — hunt a growing population of wild pig relatives,
called peccaries, that decimates crop yields
According to remains found in recent years in Els Casots, these crocodiles would also have shared their habitat with large mammals: rhinoceroses, the equid genus Anchitherium,
peccaries, mouse - deer, primitive pigs and bovines, extinct relatives of elephants (including the mastodon and a proto - elephant named deinotherium) and some carnivorous species, such as the so -
called bear dogs and felids, hyaenids and extinct mustelids.
