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.
