Fossil Megalodon Shark Tooth
Pliocene Epoch, circa 5.6 million years B.P.Sold for (Inc. bp): £247
A Carcharocles megalodon shark tooth, with serrations and good polished tooth enamel. 63 grams, 83 mm
Found Wrightsville Beach, North Carolina. Ex The Fossil Exchange. From a private Tyneside collection, formed since the early 2000s. Accompanied by a Fossil Exchange information card.
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.
