Paleotriakis is a genus of ground sharks that lived in the Late Cretaceous period of France.^[1]

Species

This genus includes two species that are originally described as species of Paratriakis .

Palaeotriakis curtirostris (Davis, 1887)
Palaeotriakis subserratus (Underwood & Ward, 2008)

However, for P. curtirostris, later studies still support its classification as a species of Paratriakis.^[2]^[3]
