In Depth Megawhaitsia is a genus of therocephalian therapsid that lived in Russia during the Permian. At the time of its description, Megawhaitsia is only known from a single portion of maxilla, the tooth bearing bone of the upper jaw. However, reconstructions of the skull of Megawhaitsia based upon scaling to the maxilla have revealed … Read more

In Depth Struthiocephalus is known from a fairly large number of individuals that represent various life stages and sexes, though originally these were broken up into distinct genera on the mistaken idea that the different growth stages and sexual dimorphism between specimens represented traits of different genera. What can be said about Struthiocephalus now is … Read more
In Depth The holotype fossils of Rhachiocephalus were originally described as a species of Oudenodon, O. magnus, in 1876 by Richard Owen. It was later in 1898 that these fossils were re-described by Harry Govier Seeley as a new genus, Rhachiocephalus. Fossils of Rhachiocephalus are currently known from both South Africa and Tanzania. One Tanzanian … Read more
In Depth Cynognathus seems to be one of the most successful of the cynodonts, with a large number of fossil remains from a wide geographic distribution being all attributed to the genus. There is however some controversy over whether all of these fossils should be labelled as Cynognathus, as the genus does seem to have … Read more
