Could walk on all fours, had a bulky body, a long tail, and an elongated head Estimated to be about 20 ft (6 m) long and weigh 1 metric ton Described in 1989 by David Weishampel and Philip Bjork, but was described as Iguanodon lakotaensis Species name refers to "the land of the Lakota and the horizon from which the type specimen was collected" Found a partial skull and parts of the skeleton Louis Rossow had found the fossils when hunting rattlesnakes on a hogback (long narrow ridge or series of hills) near Sturgis, and excavated them with the help of us family.
