The anteosaurids a group distinguished by the long front teeth and the upturned front to the jaw – are known from both Russia and South Africa, two widely- separated regions even in late Permian times, the one located about 50 degrees north and the other about 60 degrees south. The wide distribution of these and other therapsids led the way to their spectacular spread and dominance in the succeeding early Triassic. (dinosaur costume)
Features:Anteosaurus is known from more than 30 skulls and parts of the body skeleton. Sixteen skulls are well preserved and were originally used to establish about ten different species.
Nowadays they are all regarded as different growth stages of the one species. A. magnificus. It has the skull of a powerful predator, with big cutting teeth at the front and reduced teeth at the back making room for huge biting muscles. The hips are like those of a modern crocodile.
OTHER EARLY THERAPSIDS
There were several types of early therapsids. All resembled Biarmosuchus in their build and appearance, but differed enough in the details of their skulls to show them to have been quite different genera.
Eotitanosuchus:This had very large canine teeth, like a cat or a dog. and the size of these was emphasized by the fact that the incisors at the front and the rest of the teeth behind the canines were quite small. It had a long, high snout and a narrow roof to the skull.
Ivantosaurus:This was much larger than the others of the group -up to about 6m (20ft) long Some scientists regard it as a very large example of Eotitanosuchus.
Kamagorgon:The snout of this animal was quite short and the canine teeth were huge. Apart from that, the rest of the animal is unknown, as it is based on a single incomplete skull.
