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

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.

Palaeontologists think the footprints, which are up to 75cm (30in) apart, were made by a huge herbivore from the late triassic period, and now there are efforts to get them verified.

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