Ancient reptile tracks unearthed

315 million-year-old fossilised tracks of a reptile have been unearthed in Canada. The most likely track-maker was the Hylonomus lyelli reptile according to scientists. The footprints suggest reptiles evolved between one and three million years earlier than previously thought. Dr Falcon-Lang,University of Bristol, Professor Mike Benton, University of Bristol and colleagues from Britain and Canada were behind this path breaking discovery. Scientists believe that the reptiles gathering around a watering hole left the tracks preserved in sandstone. Look up the details in Journal of the Geological Society of London.
