Workshop Note
The site is of international importance, being well dated at older than 385 million years. About 200 prints represent the passage of a Tetrapod, a primitive four-legged vertebrate, across the soft sediment of a large river floodplain in Devonian times. It is a key record of the important evolutionary step of vertebrates leaving aquatic environments and breathing air on land.
