Biology:Alopiidae
From HandWiki
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, Usakias and Trigonotodus have been proposed as members of this family.[2][3]
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.[4]
