In Depth For its type Macroleter were fairly large predators that were procolopophonid parareptiles. One former species of Seymouria, S. agilis has been re-assigned as a second species of Macroleter. This makes the type species of Macroleter, M. poezicus known from Russia, and the second species, M. agilis known from the USA. There is also … Read more
In Depth Phonodus has been described as a genus of procolophonid that lived in South Africa during the earliest part of the Permian. With Phonodus being the fifth such genus from this time and location, this suggests that the procolophonids survived fairly well during the extinction that signalled the end of the Permian. Phonodus is … Read more
In Depth Belebey were bolosaurid parareptiles that lived during the early and mid stages of the Permian. Like other members of the Bolosauridae, Belebey were probably herbivores given that their teeth were most suited to processing plants. The type species of the genus from Russia, B. vegrandis could grow to around thirty-five centimetres long, but … Read more
In Depth Eomurruna is a genus of procolophonid parareptile that lived in Australia during the late Triassic. The tooth pattern of Eomurruna shows no collision of the teeth, which is a trait seen in other procolophonids that are thought to have been herbivorous. Even as a plant eater however, there is still a possibility that … Read more

In Depth Kapes was a little parareptile that was once considered to be a synonym to the earlier named Anomoiodon. Later study has no re-affirmed the validity of this genus, and now Kapes is considered to be a very close relative of Anomoiodon.

In Depth Anomoiodon was a tiny little parareptile that lived in Germany in the early Triassic. Another genus of parareptile named Kapes was once considered to be a synonym of Anomoiodon, but rediscovery of fossils and new study have now re-confirmed them to be separate genera. There are however considered to be very closely related … Read more
