WASHINGTON, May 14 -- Scientists in Australia have identified the oldest known fossil footprints of a reptile-like animal, dated to around 350 million years ago.

The discovery suggests that after the first animals emerged from the ocean around 400 million years ago, they evolved the ability to live exclusively on land much faster than previously assumed, reports AP.

"We had thought the transition from fin to limb took much longer," said California State University paleontologist Stuart Sumida, who was not involved in the new research.

Previously the earliest known reptile footprints, found in Canada, were dated to 318 million years ago.
