Eotitanosuchus which literally means ‘dawn titan
crocodile’ is a
bit of a misnomer since Eotitanosuchus was actually
a crocodile. The name Eotitanosuchus actually
came about from the
similarity of this genus to another called Titanosuchus
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.
