Ulemosaurus
''Ulemosaurus svijagensis'' was a dinocephalian synapsid that lived 265 to 260 million years ago, at Isheevo in Russian Tatarstan. It was a tapinocephalid, a group of bulky herbivores which flourished in the Middle Permian. Ulemosaurus'' and other tapinocephalians disappeared at the end of the Mid-Permian. ==Description==
Only several partial skeletons and skulls have been found. The skull bones are extremely dense: about at its thickest. This thickening is possibly related to head-butting behavior, as some researchers suggest. The species is considered a herbivore, but because the mandible is heavily constructed some palaeontologists consider it a carnivore, with the species being able to use muscle power to cut prey up with its incisors.
