Angela Foster at first thought the tooth was an arrow head
A tooth belonging to a prehistoric shark has been donated to a Kent museum after it was found in a wall.
The palm-sized incisor belonging to a creature called a Megladon was discovered by Angela Foster after her garden wall in Maidstone collapsed.
Experts at Maidstone Museum believe the tooth could be 10 million years old, but they do not know how it could have ended up where it was found.
Prof Ed Jarzembowski said the shark could easily have swallowed a human. … The Megladon, [sic Try Megalodon instead] which died out two million years ago, was 15 to 20m long and capable of devouring a large whale. – bbc
