Scapanorhynchus texanus, Menuha Formation (Upper Cretaceous), southern Israel. Near-complete fossil of S. lewisii, under special lighting. Scapanorhynchus (from Greek: σκάφιου scaphion, 'shovel' and Greek: ῥύγχος rhynchos 'snout') [3] is an extinct genus of goblin shark that lived during the Cretaceous period, from the Aptian to the end of the Maastrichtian.
The video evidence suggests that while the jaws are definitely unique, goblin sharks use ram feeding, a type of prey capture that is typical of many mackerel sharks. [30] What makes the goblin shark unique is the kinematics of their jaw when feeding. The lower jaw seems to undergo more complex movements and is important in capturing the prey.
The most distinctive characteristic of the goblin sharks is the long, trowel-shaped, beak-like snout, much longer than those of other sharks. Its long snout is covered with ampullae of Lorenzini that enable it to sense minute electric fields produced by nearby prey, which it can snatch up by rapidly extending its jaws. [ 5 ]

The goblin shark was pregnant with six babies, or pups, the museum said in a June 15 Facebook post. The pups were between about 3.9 and 4.2 feet long and each weighed about 8 pounds.
Any fossils, including fossil shark teeth, are preserved in sedimentary rocks after falling from their mouth. [13] The sediment that the teeth were found in is used to help determine the age of the shark tooth due to the fossilization process. [15] Shark teeth are most commonly found between the Upper Cretaceous and Tertiary periods. [16]
The upper side of the body is greyish brown with dark brown spots. The underside is a light greyish white. The teeth of S. canicula are larger in males than in females; in addition, male S. canicula from West African waters have stronger, larger, and more calcinated jaws. The differences in mouth dimensions and tooth length between males and ...
