A four year-old girl has found a dinosaur footprint on a beach in Wales.
A dinosaur footprint has been discovered by a four year old girl on a beach in Wales.
Lily Wilder spotted it at Bendricks Bay in Glamorgan.
Scientists say it could help establish how they walked.
The footprint is around 220 million years old and had been preserved in mud.
The print is 10 centimetres long and likely from a 75 centimetre tall dinosaur.
National Museum Wales palaeontology curator Cindy Howells described it as "the best specimen ever found on this beach".
Special permission had to be sought from Natural Resources Wales to legally remove the footprint.
The fossil will be extracted this week and taken to National Museum Cardiff where it will be preserved.
Dinosaurs first appeared about 230 million years ago.
This discovery sheds light on an early point in their evolution.
It's believed to be from when the different groups of dinosaurs were first diversifying.
"Its spectacular preservation may help scientists establish more about the actual structure of their feet as the preservation is clear enough to show individual pads and even claw impressions," National Museum Wales said in a statement.
