The discovery "will allow us to better understand the anatomy of the Prestosuchus and will help us more precisely build its ," he said.

These are the only remains that include a well preserved hind leg, "which will give us new information on the of these incredible reptiles," added Furtado Cabreira.

The remains were found in a sedimentary rock formation that was a lake millions of years ago. believe that herbivore creatures stopped to drink at the site and were ambushed by carnivores such as the Prestosuchus.
