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 .
Otodontidae is an extinct family of sharks belonging to the order Lamniformes.Its members have been described as megatoothed sharks. [1] [2] They lived from the Early Cretaceous to the Pliocene, and included genera such as Otodus, including the giant megalodon. [3]

Rolfodon is an extinct genus of shark in the family Chlamydoselachidae. It is closely related to the extant frilled sharks in the genus Chlamydoselachus, which it can be differentiated from by tooth morphology. It is named after late Canadian paleontologist Rolf Ludvigsen. [1]
An analysis of a partially complete tail fin fossil shows that Cretoxyrhina had a lunate (crescent-shaped) tail most similar with modern lamnid sharks, whale sharks, and basking sharks. The transition to tail vertebrae is estimated to be between the 140th and 160th vertebrae out of the total 230, resulting in a total tail vertebral count of 70 ...
Megalodon sharks were “the size and weight of a railroad car” and reigned over the world’s oceans “roughly 23 to 3.6 million years ago,” according to the National Museum of Natural History.
Otodus angustidens [3] is an extinct species of prehistoric megatoothed sharks in the genus Otodus, which lived during the Late Eocene and Miocene epochs about 34 to 21 million years ago. [4] The largest individuals were about 11–12 metres (36–39 ft) long. This shark is related to another extinct megatoothed shark, the famous Otodus ...
