Thescelosaurus neglectus skeletons have been found in Wyoming's lance formation since as early as 1891 but, as indicated in it's name it was 'neglected' by scientists for 20 years before being described in 1910. The genus name translates to "Marvelous" which is has to do with the fact that many of these specimens are found fully intact and at least partially articulated. This animal may have been the most common dinosaur that roamed the floodplains of the Lance and Hell Creek formations in the American west. They likely browsed the first several meters of foliage from ginkos, ferns, and cypress and the common flowering trees. Many complete skeletons are known from channel sandstone deposits, which has been taken as evidence that this species spent at least part of it's life near the river channels that meandered across the floodplains. Our mounts are posed looking backward as if the animal was 'on alert' in the presence of one of the large Tyrannosaurus with whom it coexisted.
