In his 2015 book, The Story of Life in 25 Fossils: Tales of Intrepid Fossil Hunters and the Wonders of Evolution, Donald Prothero proposed the body mass estimates for different individuals of different length by extrapolating from a vertebral centra based on the dimensions of the great white, [50] a methodology also used for the 2008 study which supports the maximum mass estimate. [51] Sold by weight from our sweet shop jar into shop sealed clear plastic weigh out bags to your selected weight from 113g (a quarter of a Pound) Another model of the evolution of this genus, also proposed by Casier in 1960, is that the direct ancestor of the Carcharocles is the shark Otodus obliquus, which lived from the Paleocene through the Miocene epochs, 60 to 13Mya. [29] [32] The genus Otodus is ultimately derived from Cretolamna, a shark from the Cretaceous period. [7] [34] In this model, O. obliquus evolved into O. aksuaticus, which evolved into C. auriculatus, and then into C. angustidens, and then into C. chubutensis, and then finally into C. megalodon.Prey relationships Vertebra of a whale bitten in half by a megalodon with visible gashes from teeth.

ISBN 978-0-12-415031-7. OCLC 212425118. O. megalodon likely had a much shorter nose, or rostrum, when compared with the great white, with a flatter, almost squashed jaw. Like the blue shark, it also had extra-long pectoral fins to support its weight and size. Mrinalini M, et al. (2015). True generalizedmacrodontia in a case of Rabson-Mendenhall syndrome.

Randall, an ichthyologist, used the enamel height (the vertical distance of the blade from the base of the enamel portion of the tooth to its tip) to measure the length of the shark, yielding a maximum length of about 13 meters (43ft). [59] However, tooth enamel height does not necessarily increase in proportion to the animal's total length. [30] :99a b c d e f g Prothero, D. R. (2015). "Mega-Jaws". The Story of Life in 25 Fossils.
