Richard Wilder said his family was walking Jan. 23 on Bendricks Bay beach in south Wales when his 4-year-old daughter, Lily, called his attention to a fossilized rock.

It was almost like someone had etched into the rock," Wilder told CBC News. The family's Facebook post with photos of the rock came to the attention of the National Museum Wales, which retrieved the fossil from the beach. "This fossilized dinosaur footprint from 220 million years ago is one of the best-preserved examples from anywhere in the U.K. and will really aid paleontologists to get a better idea about how these early dinosaurs walked," Cindy Howells, curator at the Amgueddfa Cymru National Museum of Wales Paleontology, said in a statement.

The museum said fossil will be put on display soon along with a plaque identifying Lily as the person who discovered it.
