Dentist in Ottawa Watches Tooth and Jaw Evolution Study in Prehistoric Fossils

A dentist in Ottawa is interested in an international study that scrutinized fossils of ancient jawed fish with backbones to determine the relationship between early teeth and jaws.

 
PRLog - Dec. 5, 2012 - OTTAWA, Canada -- OTTAWA, ONTARIO - University of Bristol research associate Dr. Martin Ruecklin steered a team of international researchers to inspect the evolutionary development of a primitive jawed fish. Nature, the International Weekly Journal of Science, published the corresponding paper online in October. The findings suggest teeth and jaws advanced concurrently, contrary to previous thought that early animals with backbones lacked teeth.

The research team comprises physicists and paleontologists from the U.K., Switzerland and Australia. The well-maintained fossils the team examined were from the jaws of the primitive fish Compagopiscis. The team was able to see each tissue and growth line in the fossils with high energy X-rays. The X-rays were not harmful to the fossils, and they allowed the researchers to receive comprehensive information about the development of the teeth and jaws.

"We could then make comparisons with the embryology of living vertebrates, thus demonstrating that placoderms possessed teeth," says Ruecklin. (http://www.trilliumdental.ca/blog/)

Researchers thought the first animals with backbones were lacking teeth before this fossil inspection.

"This is solid evidence for the presence of teeth in these first jawed vertebrates and solves the debate on the origin of teeth," says co-author and University of Bristol professor Philip Donaghue.

Dr. Zerina Johanson, Natural History Museum researcher and co-author on the study, says the fossils contain numerous clues to prehistoric evolution but the research had been waiting for an extremely non-invasive method such as high energy X-rays. The partnership between the paleontologists and physicists helped uncover this evolutionary research.

Bartos and Northcott are intrigued with these findings, as their work often focuses on finding the subtle equilibrium between a patient's jaw joint, teeth and muscles. The jaws and teeth work closely together to help humans chew, speak and smile. In addition to TMJ treatment, Trillium Dental's Orleans dentistry office also offers cosmetic procedures such as Kanata teeth whitening, dental veneers and gum contouring.
