Fossil Megalodon Giant Shark Tooth
Pliocene Epoch, circa 5.6 million years B.P.Sold for (Inc. bp): £169
A Carcharocles megalodon shark tooth, with serrations and polished tooth enamel. 154 grams, 11.1 cm
From a Cambridgeshire, UK, collection.
Carcharodon megalodon is regarded as one of the largest and most powerful marine predators in vertebrate history and likely had a profound impact on the 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. -
