Carcharocles megalodon tooth displaying some good polished enamel. 198 grams, 95 mm
Ex Lincolnshire, 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 structuring of the marine communities. Fossil remains indicate that this giant shark reached a length of more than 16 meters (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.
