Russia during theWordian stage of thePermian period. It is included in thesynapsid cladeCaseidae in the orderPelycosauria ."Ennatosaurus" was herbivorous, possibly using its broad forefeet to dig at plants. Like all caseids, "Ennatosaurus" had a small head compared to its wide, lizard-like body. Its mouth was lined with blunt, peg-like teeth. It lived alongside other Permian creatures, such as the herbivorous "
Nyctiphruretus " and the carnivorous "Biarmosuchus ".The adult size for "Ennatosaurus" is unknown. Fossil remains show an animal about the size of a cat, but these are likely juvenile specimens, the adults growing to sizes that may have rivaled those of convert|20|ft|m|sing=on-long cousin, "
Cotylorhynchus ". [http://scienceblogs.com/tetrapodzoology/2007/07/the_answers_we_seek_on_goodbye.php] "Ennatosaurus" is known from only one fossil site, where several juveniles were buried simultaneously in sand. One adult skull was found among the juvenile skeletons.References
