This slender fish was known as an Aspidorhynchus. Its name derives from Ancient Greek, meaning ‘ shield snout’, due to its appearance, in that it had a spike at the end of its upper jaw. Like the vast majority of fish, the Aspidorhynchus was a genus of the Actinopterygii class – which are ray finned fish. This is as opposed to the other class of fish, Sarcopterygii – lobe finned fish. It was a fast-swimming fish with heavy scales and its upper jaw was longer than its lower jaw, hence the appearance of a snout. In appearance it is similar to modern-day gars, however they are not related genealogically.
