In Depth Eriphostoma is a little known genus of gorgonopsid, but one that is important to the study of them given that Eriphostoma may well represent the earliest known gorgonopsid. There has been speculation that another genus called Broomisaurus and known only from fragmentary fossils may be junior synonym to Eriphostoma. Further Reading Further reading- … Read more

In Depth Tetracynodon is a genus of therocephalian therapsid that is noted as having lived through the Permian/Triassic extinction event, something that was probably the most dramatic extinction level event recorded in our planets history, even more devastating than the extinction that killed off the dinosaurs. One thing of note is that the Permian species … Read more
In Depth The holotype fossils of Kenomagnathus were originally thought to be of the genus Haptodus until they were formally described as a distinct genus in 2020. Although only partially preserved, the size of the lacrimal bone suggests that Kenomagnathus would have had large eyes. As a hunter, these large eyes might have helped Kenomagnathus … Read more
In Depth Lycaenops acquired its name from the striking similarity between it and modern wolves.
