       The name Eotitanosuchus which literally means‭ ‘‬dawn titan crocodile‭’ ‬is a bit of a misnomer since Eotitanosuchus was actually a therapsid,‭ ‬not a crocodile.‭ ‬The name Eotitanosuchus actually came about from the similarity of this genus to another called Titanosuchus which appeared slightly later,‭ ‬hence the‭ ‘‬dawn‭’ ‬prefix at the beginning.
       As biarmosuchian therapsids,‭ ‬Eotitanosuchus would have been predators of other Permian era animals,‭ ‬though the smaller than usual temple opening‭ (‬the hole in the skull behind the eye‭) ‬indicates that it did not have a bite as strong as other predators of the time.‭ ‬Eotitanosuchus likely shared the same habitats as Biarmosuchus and Estemmenosuchus since remains of both of these genera have been found close to remains of Eotitanosuchus.‭ ‬The genus Ivantosaurus has been considered to be very similar to Eotitanosuchus so much so to the point that the genus has even been suggested to be a synonym of Eotitanosuchus. Additionally, Eotitanosuchus has been considered to be synonymous with Biarmosuchus.
