Fossils from Proctor Lake are curated in the Shuler Museum of Paleontology at Southern Methodist University. Dozens of Hypsilophodonts occur at Proctor Lake, but none of this species is yet known from anywhere else in the world. Skeletons are found as single adults, like the specimen above, or as clusters of small adults. As many as 12 adults occur together. Flocks of young and adult Hypsilophodonts lived around the Proctor Lake area. The only other fossils found at Proctor Lake with the Hypsilophodonts are a few scraps of crocodile and one tooth o a pedator dinosaur like Deinonychus.
