In Depth
The largest species of Captorhinus approaching eighty centimetres long is C. magnus, with other species around forty centimetres long. The other difference between the species is C. aguti which has more than one row of teeth. The arrangement of the teeth at the back of the mouth suggest that Captorhinus mashed plant leaves in its mouth before swallowing.
