Cretalamna is a genus of extinct otodontid shark that lived from the latest Early Cretaceous to Eocene epoch (about 103 to 46 million years ago). It is considered by many to be the ancestor of the largest sharks to have ever lived, such as Otodus angustidens, Otodus chubutensis, and Otodus megalodon.

Physogaleus is an extinct genus of small requiem shark that lived from the Late Paleocene to Miocene epochs.

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.

Nebrius is a genus of carpet sharks in the family Ginglymostomatidae.

Palaeocarcharodon, also known as the pygmy white shark, is a genus of shark within the family Otodontidae that lived about 61.7 to 55.8 Ma during the Paleocene. It currently contains a sole species P. orientalis.
