Anomotodon
''Anomotodon'' is an extinct genus of shark related to the extant goblin shark (''Mitsukurina owstoni''). The distribution of ''Anomotodon'' fossils is worldwide, in formations indicating that members of the genus lived from the Early Cretaceous epoch through the Eocene epoch, and perhaps through the Oligocene as well. Described species include ''A. novus'', ''A. plicatus'', ''A. principalis'', and ''A. multidenticula''.

Mitsukurinidae
Mitsukurinidae is a family of sharks with one living genus, ''Mitsukurina'', and four fossil genera: ''Anomotodon'', '' Protoscapanorhynchus'', ''Scapanorhynchus'', and '' Woellsteinia'', though some taxonomists consider ''Scapanorhynchus'' to be a synonym of ''Mitsukurina''. The only known living species is the goblin shark, ''Mitsukurina owstoni''. This family of sharks is named in honour of Kakichi Mitsukuri who brought the holotype of the only species in this family to David Starr Jordon to be scientifically described. 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. They also possess long, protrusible jaws. When the jaws are retracted, the shark resembles a grey nurse shark The sand tiger shark (''Car ...
