In 2020, Cooper and his colleagues reconstructed a 2D model of megalodon based on the dimensions of all the extant lamnid sharks and suggested that a 16 meters (52 ft) long megalodon would have had a 4.65 m (15.3 ft) long head, 1.41 m (4 ft 8 in) tall gill slits, a 1.62 m (5 ft 4 in) tall dorsal fin, 3.08 m (10 ft 1 in) long pectoral fins, and ...
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]
Like contemporaneous sharks, at least two species of Otodus (O. angustidens and O. megalodon) made use of nursery areas to birth their young in, specifically warm-water coastal environments with large amounts of food and protection from predators. [14] [10] A possible reproduction area of O. obliquus has been discovered in the Ganntour basin ...
Members of the group include macropredators, generally of medium-large size, including the largest macropredatory shark ever, the extinct Otodus megalodon, as well as large planktivores. [ 2 ] Although some authors have argued that the Late Jurassic Palaeocarcharias should be considered the oldest known lamniform, this is disputed.

The largest shark in the fossil record is the megalodon (Otodus megalodon), a colossal Neogene lamniform. The range of estimates of the maximum length for megalodon are from 17 to 20.3 m (56 to 67 ft), with a mass ranging from 65 to 114 short tons (59 to 103 t). [44] [45] [46] It is also regarded as the largest macro-predatory fish ever.
