Thescelosaurus [SEP] Discovery, history, and species
The type specimen of "Thescelosaurus" (USNM 7757) was discovered in 1891 by paleontologists John Bell Hatcher and William H. Utterback, from beds of the late Maastrichtian-age Upper Cretaceous Lance Formation of Niobrara County (at the time part of Converse County), Wyoming, USA. The skeleton, however, remained in its shipping crates for years until Charles W. Gilmore of the Smithsonian Institution's National Museum of Natural History had it prepared and described it in a short paper in 1913, naming it "T. neglectus" ("neglectus": "neglected"). At the time, he thought it was related to "Camptosaurus". He provided a detailed monograph in 1915, describing the well-preserved skeleton.
