Fossil footprints found in Australia the oldest evidence of amniotes – video
by from Science | The Guardian on (#6X9TH)
Fossilisedfootprintsfound in Australia provide the oldest evidence for reptiles on Earth, a discovery that suggests the group evolved in the southern rather than the northern hemisphere, and some 35-40 million years earlier than thought. A 35cm trackway of clawedfootprintsfound in sandstone on Taungurung country, near Mansfield in eastern Victoria, have been dated to between 354 and 358m years old in a paper published in Nature, making them the oldest on record. The previously oldestfossilrecords, from Europe and North America, are estimated at 318m years old
