Knobby Pareiasaurs

During the Permian era, the Earth was dominated by a single supercontinent called Pangea – “All-Earth”. Animal and plant life dispersed broadly across this land, as documented by identical fossil species found on multiple modern continents. But a new study published in the Journal of Vertebrate Paleontology supports the idea that there was an isolated desert in the middle of Pangea with a fauna all its own. Roaming this desert in what is now northern Niger was a very distinctive creature known as a pareiasaur.
