“This is the earliest evidence we’ve ever seen of an animal with claws,” said Sumida.At the time the ancient reptile lived, the region was hot and steamy and vast forests began to cover the planet. Australia was part of the supercontinent Gondwana.

The fossil footprints record a series of events in one day, Ahlberg said. One reptile scampered across the ground before a light rain fell. Some raindrop dimples partially obscured its trackways. Then two more reptiles ran by in the opposite direction before the ground hardened and was covered in sediment.Fossil “trackways are beautiful because they tell you how something lived, not just what something looked like,” said co-author John Long, a paleontologist at Flinders University in Australia.
