Gilmoreosaurs lived during the Cretaceous period. Its remains were discovered of this ornithischian in China.

Several expeditions were carried out by the American Museum of Natural History. Gilmoreosaurs' fossil remains were found by George Olsen. Specimens were found from two different quarries in Mongolia, a few kilometers northeast of Erenhot in China. The fossils were studied and were concluded to be a new species named Mandschurosaurus and G. mongoliensis by C. W. Gilmore. In 1979, Michael K. Brett-Surman named the genus Gilmoreosaurus to honor CW Gilmore.

Did You Know...

Charles Whitney Gilmore was an American paleontologist who studied North American and Mongolian dinosaurs. Gilmore named several dinosaur genera based on uniquely relevant features, including Alamosaurus and Bactrosaurus. The dinosaur genus Gilmoreosaurus found in China was named in his honor.

Dr. Brett-Surman described the Gilmoreosaurus reptile in 1979. The nomenclature 'Gilmore's lizard' is no longer being followed by scientists.

Evidence of tumors like metastatic cancer, osteoblastoma, and hemangiomas have been found on the specimens of the genus Gilmoreosaurus. Many other hadrosaurids had these tumors too.

Additional specimens found in Uzbekistan of G. atavus and the G. arkhangelskyi were described as distinct species. Since these are based on very fragmentary remains and fossils, their classification is dubious. Another species, G. kysylkumense, is said to belong to a related genus, Bactrosaurus, sometimes.

There's more information available in 'Journal of Vertebrate Paleontology' on evolution, vertebrate origins, and more. Several other papers regarding the growth and evolution of hadrosauroids have been published as well.

Michael K. Brett-Surman brought about a change in the taxonomy of this dinosaur when he named the genus Gilmoreosaurus.
