It is plausible that the adult megalodon population off the coast of Peru targeted primarily cetothere whales 2.5 to 7 meters (8.2 to 23 ft) in length and other prey smaller than itself, rather than large whales in the same size class as themselves. [70] Meanwhile, juveniles likely had a diet that consisted more of fish. [34] [74]
Prehistoric Predators is a 2007 National Geographic Channel program based on different predators that lived in the Cenozoic era, including Smilodon and C. megalodon.The series investigated how such beasts hunted and fought other creatures, and what drove them to extinction.
English: A size diagram comparing various size estimates for the extinct shark Otodus megalodon to Carcharodon carcharias (great white shark), Rhincodon typus (whale shark), and a human. Also shown are megalodon specimens the estimates are based on, vertebral column IRSNB P 9893, upper anterior tooth NSM PV-19896, and lateral tooth GHC 6.
[3])and Carcharodon megalodon (Average estimated adults size about 16 - 18 m, and a largest size of 20.3 m was extrapolated from ontogenetic trends of the great white shark by Gottfried et al. 1996. [ 4 ] ) to a human Homo sapiens (180 cm).
A new study posits that the ancient megalodon shark was longer and slimmer than previously believed. The ancient shark has been compared to the great white, but it may have more closely resembled ...

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.
Size of Paraceratherium (dark grey) compared to a human and other rhinos (though one study suggests Palaeoloxodon namadicus may have been a larger land mammal). The blue whale is the largest mammal of all time, with the longest known specimen being 33 m (108.3 ft) long and the heaviest weighted specimen being 190 tonnes.
