Thank you!

By the way, now we know that in reality "canines" of Ivantosaurus was shorter (originally the was very deformed and it's lenght was estimated as 18-19 cm, in reality - 13-14 cm)!

I was hoping it may be a Smilodon-analogue of Permian age indeed :lol: :XD:

As for me I won't edit my picture of this beast ;p

In most of therapsids upper "canines" (in reality, caniniform teeth)was not so long as in sabertooth cats. Older cranial reconstructions (for example, for Rubidgea)was based on deformed skulls.

Is very controversial the names and synonymy of Eotitanosuchus, Biarmosuchus and Ivantosaurus, I think it is possible that all are treated the same genre .
Biarmosuchus is perhaps juvenile, Eotitanosuchus sub-adult and old adult Ivantosaurus :-?
It is also possible that other species biarmosuchus ( B. tagax y B. tchudinovi ) are juvenile Ivantosaurus and Eotitanosuchus ?

This genre must be Biarmosuchus, because Biarmosuchus and Eotitanosuchus was described in same paper, but Biarmosuchus is based on better remains. So, Biarmosuchus (in sensu stricto) is juvenile, "Eotitanosuchus" - adult, "Ivantosaurus" - old. Or Eotitanosuchus is adult female, who knows? Two others species of Biarmosuchus, of cause, can be juveniles, but they known only by remains of small individuals.
