Genera

Alopiidae is a family of large mackerel sharks (order Lamniformes). [1] The only extant genus is the thresher shark (Alopias). The extinct genera Anotodus , Paranomotodon , and Trigonotodus have been proposed as members of this family.

It is believed that thresher sharks originated from a common ancestor that appeared in the Late Cretaceous, at least 70  million years ago. The first thresher sharks of the genus Alopias appeared about 50  million years ago.[ citation needed ]Trigonotodus is known from the Oligocene. [2]
