Moythomasia (20 cm.)
Made for Martin Rücklin, University of Bristol.
Myothomasia is an extinct genus of early ray-finned fish from the Devonian period. Fossils have been found in Germany and Western Australia.
Moythomasia was a small freshwater fish, growing to 9 centimetres in length. It had relatively large eyes, presumably to find prey in murky water. Its body was covered in specialized ganoid scales; the upper side of each scale sported a small pin that perfectly fit into the hollow lower side of the next scale. This allowed the fish to be both armored and flexible.
