Newly discovered fossilised footprints provide the earliest evidence yet for the evolution of reptiles – a major event in the history of life. They are 315 million years old, making reptiles up to 3 million years older than previously thought.

Ancient reptile tracks unearthed
..."However, the prints showed that the hands had five fingers and scales, sure evidence they were made by reptiles and not amphibians."
The most likely contender was a lizard-like reptile named Hylonomus lyelli after the 19th Century geologist Sir Charles Lyell.
Until now, the oldest evidence for reptiles was thought to be skeletal fossils of the creature found in 1859 by William Dawson...
John Calder, senior geologist with the Nova Scotia department of natural resources, argues there are flaws in the evidence Falcon-Lang uses to support his view the fossils are the oldest record to date.
Calder told the Chronicle Herald that, judging by photographs, the footprints are too large to be made by reptiles. And while Falcon-Lang claims the fossilized footprints are older than the skeletons because he found them almost a kilometre below levels of the 1859 discovery, that may not be true, said Calder.
