A six-year-old discovered a shark tooth from a prehistoric megalodon that could be 20 million years old. During a bank holiday break in Suffolk, Sammy Shelton discovered the 10cm (4in) tooth on Bawdsey beach. Prof. Ben Garrod, a shark expert, confirmed that it belonged to a megalodon, the world’s largest shark. According to his father, Peter Shelton, Sammy slept with it near his bed since he was so connected to it. The Great Yarmouth Mercury said that the couple from Bradwell near Gorleston-on-Sea in Norfolk were digging for fossils when they discovered the massive shark’s tooth. Prof. Garrod, a broadcaster and evolutionary scientist at the University of East Anglia in Norwich, was emailed photos of the discovery. It belonged to a megalodon, the world’s largest shark, according to Prof. Garrod. He went on to say that its teeth were not common along the UK shoreline, with only a few being discovered each year, but this was an exceptional example, in excellent shape despite being worn when discovered.
