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 ...
Megalodon is an extinct genus of bivalve molluscs that reportedly lived from the Devonian to the Jurassic period. [1] It is not clear, however, that all the fossils assigned to Megalodon from that span of time really belong in the same genus. Jurassic relatives of Megalodon such as Pachyrisma grande were closely related to the rudists. [2]
The Lamniformes also include the extinct megalodon, Otodus megalodon. Orectolobiformes: They are commonly referred to as the carpet sharks, including zebra sharks, nurse sharks, wobbegongs, and the whale shark. Pristiophoriformes: These are the sawsharks, with an elongated, toothed snout that they use for slashing their prey.

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.
