Britain's oldest amphibian tracks have been discovered etched into a sandstone fossil in North Yorkshire.

The tracks belong to the earliest relatives of modern amphibians, called temnospondyls - specifically the edopoids, or 'glutton-faced animals'. Edopoids were crocodile-like creatures which measured up to six feet (two metres) long and lived on river deltas. Ms Bird said: 'We used scanning and photography to make a 3D digital model, allowing us to better visualise and identify the footprints and invertebrate traces.
