355-Million-Year-Old Fossil Tracks Push Back Reptile Origins
- Scientists discovered fossil footprints with hooked claws in a sandstone slab near Mansfield, Victoria, dated about 356 million years ago.
- The tracks likely belong to early amniotes, reptiles whose eggs develop inside amniotic fluid, allowing reproduction away from water sources.
- The slab shows clear claw indentations and raindrop impressions, suggesting the animals walked on land soon after the surface was exposed to air.
- John Long said the footprints are a "dead giveaway" of an amniote, pushing back the origin of land-living animals with claws by over 35 million years.
- This find implies amniotes and modern tetrapods evolved sooner than thought, significantly revising the timeline of terrestrial animal evolution.

Oldest fossil footprints from reptile found in Australia (Sorry, Canada)
Scientists in Australia have identified the oldest known fossil footprints of a reptile-like animal, dated to around 350 million years ago. Previously the earliest known reptile footprints, found in Canada, were dated to 318 million years ago.
355 million year old footprints hint at new insights into land animal evolution
Researchers in Australia have found fossilized footprints of the oldest known reptile ever. The scientists estimate the prints to be around 355 million years old, which means that such land animals walked the earth 35 million years earlier than previously thought. According to the scientists, their discovery, which was published yesterday in the scientific journal Nature, sheds new light on the evolution of land animals. This evolution is said t…
Fossil Footprints Are Rewriting History of Evolution
Scientists in Australia have identified the oldest known fossil footprints of a reptile-like animal, dated to around 350 million years ago, around 100 million years before the earliest dinosaurs. The discovery suggests that after the first animals emerged from the ocean around 400 million years ago, they evolved the ability...
