Procolophon (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Procolophon was a genus of lizard-like reptiles with at least eight species that persisted through the Permian-Triassic extinction event, but became extinct in the later Triassic. The skull was solid but some species did evolve a in the skull independently of other reptiles. There was one backward facing cheek spike, but its function is debated; it may have been for muscle attachment. Eyes were large and may have had acute day or night vision. The teeth were peg-like and suitable for crushing of plant matter. The front of the skull was short and blunt with the nasal opening very close to the mouth.
