Large Megalodon Giant Shark Fossil Tooth
Pliocene Period, 5.2-2.5 million years B.P.Sold for (Inc. bp): £390
From Carcharocles megalodon polished, showing some good enamel. 369 grams, 11.9 cm
From Aurora, North Carolina, USA. From the private collection of Kenneth Machin (1936-2020), Buckinghamshire, UK; his collection of antiquities and natural history was formed since 1948; thence by descent.
Carcharodon megalodon is regarded as one of the largest and most powerful marine predators in vertebrate history and likely had a profound impact on structuring of the marine communities. Fossil remains indicate that this giant shark reached a length of more than 16 metres (52 ft) and also affirm that it had a cosmopolitan distribution. Scientists suggest that in life it looked like a stockier version of the great white shark, Carcharodon carcharias.
