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). [41] [42] [43] It is also regarded as the largest macro-predatory fish ever.
Largest specimen of Leedsichthys compared to other Pachycormid fish. Leedsichthys is the largest known member of the Osteichthyes or bony fishes. [20] The largest extant non-tetrapodomorph bony fish is the ocean sunfish, Mola mola, being with a weight of up to two tonnes an order of magnitude smaller than Leedsichthys.
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 ...
Fossil remains show a trend for specimens to be larger on average in the Southern Hemisphere than in the Northern, with mean lengths of 11.6 and 9.6 meters (38 and 31 ft), respectively; and also larger in the Pacific than the Atlantic, with mean lengths of 10.9 and 9.5 meters (36 and 31 ft) respectively.
The Megalodon was a prehistoric shark, much like a great white ... but 60-feet long. Researchers don't actually believe it was a Megalodon, but they do think it was a giant shark: a great white ...
It exceeded 3 m (9.8 ft) in length, and would have weighed in at around 200 kg (440 lb), much larger than any other known mustelid, living or extinct. [159] [160] [161] There were other giant otters, like Siamogale, at around 50 kg (110 lb) [162] and Megalenhydris, which was larger than a modern-day giant river otter. [163]

Like other known megatooth sharks, the fossils of O. angustidens indicate that it was considerably larger than the extant great white shark, with the largest individuals possibly measuring up to 11–12 metres (36–39 ft) long. [7] [8] A well preserved specimen from New Zealand is estimated at 9.3 m (31 ft) in length. [5]
