Scapanorhynchus had an elongated, albeit flattened snout and sharp awl-shaped teeth ideal for seizing fish, or tearing chunks of flesh from its prey. It was a small shark normally measuring about 65 cm, though the largest species, S. texanus, is thought to have reached up to 3 m (10 ft) in length, about the size of a modern goblin shark.[5][6] The largest teeth reported from this genus are anterior teeth from S. texanus, which can reach lengths up to 7 cm.
