Anteosaurus magnificus v Inostrancevia alexandri
Anteosaurus magnificus
Anteosaurus (meaning "previous or early reptile") is the name given to an extinct genus of large carnivorous synapsid. It lived during the Capitanian epoch of the Middle Permian (266-260 million years ago) in what is now South Africa. They became extinct by the middle Late Permian. Blaire Van Valkenburgh And Ian Jenkins Anteosaurus was a semi aquatic synapsid with a long tail and weak limbs, which indicate a lifestyle including water, much like that of a crocodile. Anteosaurus weighed approximately 500-600 kg and was over 5 m long. Its most notable characteristic is its tall, narrow skull, which is 80 cm long. The size of the skull is used to determine the age of a fossil. The teeth are another identifying characteristic of Anteosaurus. The teeth on the roof of the mouth are enlarged and confined in a cluster near the outer tooth row. The "normal teeth" include the anterior, canine and cheek teeth. A prominent feature of the Dinocephalians is the ledge on the anterior teeth. The canine teeth are big, and there are usually about 10 cheek teeth present. The front of the mouth curves up due to the premaxillary bone of the upper jaw. Paleontologists believe the presence of pachyostosis (thickening of the roof of the head) indicates a "head-butting" behavior of these dinocephalians, probably for protecting territory and fighting over a mate. This feature indicates that they were active on land as well.

Inostrancevia alexandri
Inostrancevia is a genus of gorgonopsid therapsid found in Sokolki, on the Smaller Northern Dvina River near Kotlas in Arkhangelsk Oblast, Russia. The animal lived 251 million years ago during the Late Permian. The species I. alexandri is known from an almost complete skeleton missing some minor rib and vertebrae attachments. t was the largest of the gorgonopsids, weighing 500-1000 pounds and measuring 4.3m long (about the size of a large bear). It's skull measured 45 cm long and it had two 12cm long saber teeth that it used to dispatch enemies and prey. As with all other gorgonopsid species, it was a quadruped that had an upright posture of 1-4.3 metres long (as large as a bear), with a bone structure characteristic of strong muscle attachments. The skull of 45 cm in length contained a smaller eye socket and larger temporal opening than other less advanced therapsids, like Biarmosuchus tener. The teeth were quite large, the upper palate containing 6 large incisors, 2 large canines and 10 smaller back teeth and the mandible contained 6 large incisors and 8 smaller incisors.

Its a close fight as both have strong jaws and teeth but the anteiosaurus has the additional head butting weapon.

I see the latter has got more votes than the former. Anyone else care to comment?
