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.
