The oldest fossil footprints present in Australia
Scientists in Australia have identified the oldest known fossil footprints of an animal such as a reptiles in Australia about 350 million years ago.
The discovery suggests that after the earlier animals emerged about 400 million years before the sea, they had especially developed the ability to live especially on the land, which was much faster than before.
“We thought it had taken longer infection from Finn to Limb,” said Stuart Sumida, a peliytologist at California State University.
already The earliest found in Canada was dated 318 million years ago.,
The ancient footprints from Australia were found on a slab of sandstone recovered near Melbourne and shown legs such as a reptile with long toes and bent claws.
Scientists estimate that the animal was about 80 cm long and a modern monitor may be similar to lizard. There were conclusions Published in Nature on Wednesday,

First animal with claws
Hook Claw is an important identity clue, said at the University of Upsala, Sweden, co-writer and peliytologist per Ahbarg.
“It’s a moving animal,” he said.
Only animals that developed to develop perfectly on land, sometimes developed claws. First vertebrae – fish and amphibians – never developed rigid nails and depended on the environment of water to lay eggs and breed.
But the branch of the evolutionary tree that led to modern reptiles, birds and mammals – known as amniotes – fit to walk on hard ground with nails or claws developed with nails or claws.
Sumida said, “This is the first proof we have ever seen an animal with claws.”
At the time when ancient reptiles lived, the area was hot and full of steam and started covering the huge forest planet. Australia was part of Supercontinent Gondwana.
The fossil footprints record a series of events in a day, Ahberg said. A reptiles were surrounded on the ground before light rain fell. Some raindrop Dimple partially obscured its trackway. Then two more reptiles ran in the opposite direction before the land became hardened and covered in sediment.
The fossils “trackways are beautiful because they tell you how something lived, not just what something looked,” said John Long, a fossilist at Flinders University in Australia.
