Gilmoreosaurus

- Gilmoreosaurus arkhangelskyi
- Gilmoreosaurus atavus (possibly nomen dubium )
- Gilmoreosaurus mongoliensis
Gilmoreosaurus ( " Gilmore's lizard" ) was a genus of dinosaur bird Beck from the group of Hadrosauridae. Fossil finds date from the Late Cretaceous ( Campanian ). Fossils of the type species T. mongoliensis were found in the Gobi Desert in Inner Mongolia and described in 1933.
Features
Gilmoreosaurus reached a body length of eight meters and a weight of two tons. He was comparatively strong, but at the same time lighter than other hadrosaur. As a very original hadrosaur he resembled in shape and especially in the training of the hand claw Iguanodontidae or Iguanodon. Especially on the hind legs, he distinguished himself by large muscle attachment surfaces.
From Gilmoreosaurus mongoliensis only items of a skull are known in G. atavus you know even just individual teeth. Scope richer material in the form of skull parts, vertebrae, ribs, and pelvic parts is arkhangelskyi available by G..
Localities
The first fossils of Gilmoreosaurus mongoliensis were found in 1933 in the Irish - Dabasu formation near the town Eren Hot in Inner Mongolia, People's Republic of China in the Gobi Desert. In 1921 were discovered by the American paleontologist Roy Chapman Andrews in this rich archaeological site first dinosaur remains.
In the Irish - Dabasu lineup a number of other dinosaur skeletons have been discovered in various excavations, including the theropods Alectrosaurus olseni and Archaeornithomimus asiaticus and Bactrosaurus johnsoni another representative of the hadrosaur. In the nearby Minhe formation, which is also assigned to the Upper Cretaceous, there were more species, including the Velociraptor mongoliensis ( theropods ) which Protoceratopsiden Microceratops gobiensis and Protoceratops andrewsi and the remains unallocated theropods and sauropods.
System
Gilmoreosaurus probably represents an early hadrosaur from the relationship of Telmatosaurus dar. also probably is more closely related to the genera Claosaurus, Tanius and Secernosaurus, but a more accurate assignment it is currently due to the scanty material is not present.
The type species Gilmoreosaurus mongoliensis was first discovered in 1933 by Charles W. Gilmore and described together with a number of other dinosaurs. He described him as Mandschurosaurus mongoliensis, rearranging and scientific description of the genus was made in 1979 by Michael K. Brett - Surman, who named it after Gilmore.
Within the genus up to three species are considered valid according to the source. In addition to the type species of the genus G. mongoliensis the species G. atavus described both in 1995 by Lev Alexandrovich Nessov as part of a comprehensive revision of the Russian dinosaur finds are also (validity controversial, possibly dubium a noun ) and G. arkhangelskyi slammed. G. kysylkumensis shall be considered together with Bactrosaurus kysylkumensis as a noun dubium.
