When 10-year-old Tegan went for a summer holiday beach stroll with her mum, she had no idea they would actually be walking in the footsteps of dinosaurs, BBC reports.

The schoolgirl spotted five enormous footprints that dinosaur experts believe are the mark of a camelotia that was there more than 200 million years ago.

Tegan and mum Claire have been told by the National Museum Wales palaeontology curator that she is "fairly certain they are genuine dinosaur prints".

"We've got five footprints and we're talking about half-to-three-quarters of a metre between each one," Cindy Howells told the BBC's Our Lives programme.

"These footprints are so big, it would have to be a type of dinosaur called a sauropodomorpha."

Tegan's monster discovery was on the south Wales coast near where her mum used to live.
