Gilmoreosaurus (meaning "Charles Whitney Gilmore's lizard") is the name given to a genus of dinosaur from the Cretaceous of Asia. The type species is Gilmoreosaurus mongoliensis. It is believed to be a hadrosaur or iguanodont from the Iren Dabasu Formation of Inner Mongolia, dating to 96 Ma ago. Additional specimens have been described as distinct species, including G. atavus from the Khodzhakul Formation of Uzbekistan (120 Ma ago) and G. arkhangelskyi from the Bissekty Formation (89 Ma ago). However, these are based on very fragmentary remains, and their classification is dubious. An additional species, G. kysylkumense (also from the Bissekty Formation) is sometimes included, though it has also been referred to the related genus Bactrosaurus.
As such, he coined the genus Gilmoreosaurus in 1979, honouring Gilmore, and created the new combination Gilmoreosaurus mongoliensis. He considered Gilmore's...
