"Ulemosaurus svijagensis" was a dinocephalian synapsid related distantly to Estemenosuchids but lived 250 MYA, that is 5 million years later than "Estemenosuchus" at Isheevo in Russian Tatarstan.

Only several partial skeletons and skulls have been found. The skull bone is extremely dense: about 10 cm at its thickest. 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.
