Scapanorhynchus (from Greek: σκάφιου scaphion, 'shovel' and Greek: ῥύγχος rhynchos 'snout')[1] is an extinct genus of shark that lived from the early Cretaceous until possibly the Miocene if S. subulatus is a mitsukurinid and not a sand shark.[2][3] Their extreme similarities to the living goblin shark, Mitsukurina owstoni, lead some experts[4][5] to consider reclassifying it as Scapanorhynchus owstoni. However, most shark specialists regard the goblin shark to be distinct enough from its prehistoric relatives to merit placement in its own genus.
Scapanorhynchus had an elongated, albeit flattened snout and sharp awl-shaped teeth ideal for seizing fish, or tearing chunks of flesh from its prey. Scapanorhynchus normally did not exceed total length 4.15 metres (13.6 ft), although largest teeth with height about 6 centimetres (0.20 ft) indicates upper total length of 6.7 metres (22 ft).[6]
