Emydops
Emydops is an extinct genus of dicynodont therapsids from the Middle Permian to Late Permian of what is now South Africa. The genus is generally small and herbivorous, sharing the dicynodont synapomorphy of bearing two tusks. In the following years, the genus grew to include fourteen species. Many of these species were erected on the basis of differences in the teeth and the positioning of the frontal and parietal bones. A 2008 study narrowed Emydops down to two species, E. arctatus (first described by English paleontologist Richard Owen as Cistecephalus arctatus in 1876) and the newly described E. oweni. and Emydops arctatus (beside the bottom of the scale) to scale
