What began as a leisurely stroll on the beach for a 10-year-old girl suddenly became a paleontologist’s dream.

Tegan was recently visiting South Wales with her family when she happened upon five large footprints that experts believe belong to dinosaurs, according to the BBC and Herald Wales.

The girl and her mother Claire, whose surnames were not disclosed, were reportedly searching for fossils in the Vale of Glamorgan when Tegan made the discovery.

“We found big holes that looked like dinosaur footprints,” Tegan recalled, according to the BBC. “So mum took some photos, emailed them to the museum and it was from a long-necked dinosaur.”

Experts believe the prints are genuine. “We are pretty sure that these are genuine dinosaur prints,” said Cindy Howells, palaeontology curator at the National Museum Wales, in the latest episode of the BBC programme The Dino Hunters.

According to Howells, the dinosaur appears to belong to the Sauropodomorpha family.

Paleontologists suspect that the prints may actually belong to a Camelotia, a herbivorous dinosaur that roamed the area more than 200 million years ago.

Tegan and Claire previously lived near where the fingerprints were found, according to the Herald Wales.

The 10-year-old said it was “cool and exciting” to find the footprints, according to the BBC. She and her mother shared photos of their discovery with the National Museum Wales.

Claire said she was thrilled that Tegan got to experience something so unique. “You can spend your whole life looking for dinosaur treasures and for it to happen to Tegan at this age is amazing,” she explained.

According to the BBC, the footprints that the ten-year-old found were about 75 centimeters apart and Herald Wales.

“If they were random holes, we would be cautious,” Howells said, according to the BBC report, “but because we have a left foot, a right foot and then a left and a right … there is a consistent distance between them.”
