==Discovery and naming== thumb|left|Maps showing location of fossils In May 1985, James "Rusty" Branch at the Proctor Lake in Comanche County, Texas, discovered a dinosaur fossil site which was among the richest from the Lower Cretaceous of North America. The Shuler Museum of Paleontology, part of the Southern Methodist University at Dallas, excavated a large number of specimens on the southeastern bank of the lake, in the Camp Quarry and the North Quarry. The discovery was in 1988 reported in the scientific literature. Remains found were combined into three mounted skeletons displayed at respectively the Proctor Lake US Army Corps of Engineers Office at Proctor (based on specimen SMU 70456), the Perot Museum of Nature and Science, (a composite of specimens SMU 74087, SMU 74093 and SMU 74104), and the Fort Worth Museum of Science and History (based on specimen SMU 74663). The taxon, new to science, was informally indicated as the "Proctor Lake hypsilophodontid". Later it was understood that the Hypsilophodontidae are an invalid paraphyletic grouping.
