Still Waters Posted October 18, 2012 #1 Share Posted October 18, 2012 Scientists have found fossil evidence of the first animal to grow a set of pearly whites — a prehistoric fish that lived more than 380 million years ago. An international research team discovered teeth in several specimens of an ancient fish species, known as placoderms, a finding that likely represents the origins of teeth and jaws in animals. A full set of chompers has been key to the success of most top predators. http://www.smh.com.a...1018-27sae.html Link to comment Share on other sites More sharing options...

BaneSilvermoon Posted October 21, 2012 #6 Share Posted October 21, 2012 This makes perfect sense when looking at the development of sharks teeth, a fish. Their ancestors were once toothless and used an ancient version of the placoid scales in their skin to help grip prey. Some of those scales that make their skin rough eventually developed into full teeth. Link to comment Share on other sites More sharing options...
C235 Posted October 21, 2012 #7 Share Posted October 21, 2012 The skeptical view of this discovery would be how could they succeed without dentists?! Link to comment Share on other sites More sharing options...
