Researchers have recently witnessed a miracle of sorts: they found an extremely tiny Cambrian fossil in western Canada.
The “exceptionally well-preserved” loriciferan is less than a millimetre long. Scientists think that it was far too small to have been fossilised.
Dr Tom Harvey (Department of Geology, University of Leicester) co-discoverer of the fossil explains why the discovery is important:
“Loriciferans lack hard parts (they have no shell), so no-one expected them ever to be found as fossils -- but here they are! The fossils represent a new genus and species, which we name Eolorica deadwoodensis, loosely meaning the ‘ancient corset-animal from rocks of the Deadwood Formation.’ "
The discovery defies belief in millions of years. It should definitely not be possible for soft animals to retain their shape for half a billion years.
