Thescelesaurus Dinosaur ToothDescription: This is fine rooted tooth of the ornithopod dinosaur Thescelosaurus. Thesceleosaurus was most like lyherbivorous; ridges on both the maxillae and the dentary are indicative of chek puches, a feature that would have proved useful in keeping food from falling out of the mouth while it was being masticated. In 2000 an example of this dinosaur called Willo caused quite a Thescelosaurussensation in that it was claimed to have had internal organs including the heart preserved in situ. Today most researchers do not believe it to be the case. In any event, Willo stirred up renewed interest in this bipedal dinosaur. It was one of the last non-avian dinosaurs extant, and has been found as close as 3 meters below the end-Cretaceous iridium layer that signaled the mass extinction.
