Rare 6ft mammoth tusk discovered off the coast of Mersea Island.
Mammoths roamed the Earth more than 100,000 years ago and most populations of the ancient animal were wiped out by the most recent Ice Age.
They were roughly around the size of African elephants, weighed around six tonnes and were up to 10 feet tall.
The Natural History Museum took samples from the tusk and December 2018 reported that the tusk was thought to be 12,000 years old.
