Forgotten fossil indicates earlier origin of teeth
Leiden, Netherlands (SPX) Jun 28, 2015
The tooth plate of just some millimeters in size had been in a box for more than 40 years, without being recognized after the discovery and preparation of the fish it belonged to. Palaeontologists from Naturalis Biodiversity Center, Netherlands and the University of Bristol, United Kingdom, studied the fossil using high energy X-rays at the Swiss Light Source at the Paul Scherrer Institut in Switzerland, revealing the structure and development of teeth and bones. Their findings are published today in Bi ... read more
