Check out this 'mammoth' find from seven-year-old Nina.

She found this chunk of bone on a beach in east Suffolk while she was out hunting for shark teeth with her dad and brother.

Experts say it could be between 100,000 and 500,000 million years old and could have come from a mammoth or another large mammal.

Nina's sensibly hidden it in a special box in her bedroom to keep it safe.

Professor Ben Garrod, from the University of East Anglia, told the BBC:

"It's from something bigger than a cow, from a mammoth, Irish elk and aurochs to more unusual stuff like wild horse or rhino.

"So far as I can say, it is old, sub-fossilised, and probably Pleistocene - it's a massive ballpark, but most likely somewhere between 100,000 and half a million years old.

Ipswich Museums told the BBC that the bone could be from a rib but it could also be from a horn.

Suffolk is known for its fossils from the Pleistocene era which is also known as the Great Ice Age.

"When it was walking around Suffolk, it could have walked all the way to mainland Europe, as the North Sea wasn't there then.

"It is a lovely find and real piece of prehistory."
