==History== thumb|left|G. hayi skull (specimen AMNH 969) The first specimen referred to Galeamopus was collected by Marshall P. Felch in September, 1884 at his quarry in Garden Park, Colorado. The specimen consisted of a partial skull and mandibles, which Felch sent to his employer at the Yale Peabody Museum, Othniel Charles Marsh, but was later deposited at the National Museum of Natural History (USNM V 2673). It was referred to Diplodocus for many years until Tschopp et al referred the remains to Galeamopus in 2015 and Galeamopus pabsti in 2017.
