ScienceDaily (Apr. 3, 2012) — You are what you eat is truism that has been given new impetus by 'cutting edge' research led by the University of Leicester that reveals your teeth are literally shaped by your food.
Indeed, evidence from teeth can be used to determine what has been eaten by an animal providing a new way of working out the diets of wild animals that doesn't involve the unpleasant task of looking at the contents of their guts.
Scientists say it is also possible to use these methods to investigate diets of extinct animals such as giant marine reptiles and dinosaurs.
Research led by the Department of Geology at the University of Leicester, published in the Royal Society journal Interface, shows that the roughness of tooth surfaces can reveal what an animal has been eating.
