Estemmenosuchus mirabilis (meaning "Wondrous Crowned Crocodile") was a large herbivorous dinocephalian therapsid from Ocher in the Perm region or Russia, and lived 255 million years ago along with Estemmenosuchus uralensis, Eotitanosuchus olsoni and Biarmosuchus tener in the same habitat. The variety of species that haven't survived the fossilization process for the same habitat would include many and varied species covering all taxonomical groups. So we can't get an accurate view of its entire habitat. There were many complete and incomplete skeletons found together.
