Rodney D. Scheetz and his family discovered a fossil locality around five miles from Uravan, Colorado in the spring of 1972. This site, unintentionally exposed by a bulldozer, was found to contain fossil fragments, said to be in such condition they looked like unfossilized bone. The site was noted in a 1973 paper, and Scheetz continued to dig at the site annually until publishing a short note in 1991. By then around 2500 fragments had been excavated, almost all of which specimens are thought to have belonged to "Dryosaurus". At least eight individuals are represented, with ages ranging from juvenile to embryonic; finding specimens of embryonic age is exceptionally rare for dinosaur fossils. Eggshells were also represented in the sample. Scheetz voiced his intention to continue work at the site following the publishing of the note.
