In 1891, two years after the naming of "Triceratops", a pair of ceratopsian skulls with elongated frills bearing holes were found in southeastern Wyoming, Niobrara County, by John Bell Hatcher. Hatcher's employer, paleontologist Professor Othniel Charles Marsh, coined the genus "Torosaurus" for them.
