Picture MUST credit: Flinders University Fossil tracks have been discovered that show reptiles appeared on Earth up to 40 million years earlier than previously thought, The evidence was discovered at an Australian fossil site that represents a critical time period. Professor John Long and colleagues from Australia's Flinders University identified the tracks of an early animal with clawed feet – most probably a reptile. They date from the Carboniferous period of about 350 million years ago. They were uncovered in the Mansfield district of northern Victoria and were made by an animal that would have looked like a small, stumpy, reptile-like creature. Fossil records of mammals, birds and reptiles begin in the Late Carboniferous period of about 318 million years old. Previously the earliest body fossils were from about 334 million years ago, and the oldest trackways about 353 million years. This had suggested the modern tetrapod group originated in the early Carboniferous period, with the modern amniote group appearing in the early part of the Late Carboniferous period. But the new find has now completely re-written the timeline.
