The palaeontology world has been flipped on its head after trilobite fossils dating back 509 million years were found perfectly preserved by volcanic ash in Morocco.

Not only are they the oldest known trilobite fossils, but they are the most well-preserved, giving palaeontologists their first glimpse of trilobite anatomy.

University of New England palaeontologist and investigation co-lead, Professor John Paterson, said it went against everything he was taught.

Very interesting and threadworthy.

So, it is now threaded.
