"Eotitanosuchus olsoni" ("Olson's dawn giant crocodile") was a mammal-like "reptile" occurring in the town of Ochyor in Perm Krai, Russia, in channel flood deposits along with "Biarmosuchus tener", "Estemmenosuchus uralensis" and "Estemmenosuchus mirabilis".It lived about 255 mya and was a very large animal; although the skull usually shown is about 35 cm long, this belongs to a juvenile, it is estimated that the adult skull would be about 1 meter long. Like "Biarmosuchus tener", it was primitive in that, though it was a predator, the temple opening behind the eye was small, giving it a weak bite. The temple was, however, larger at the top than in the biarmosuchians.
