Hadrosaurids (from Ancient Greek ἁδρός (hadrós) 'stout, thick' and σαύρα (saúra) 'lizard'), or hadrosaurs, are members of the ornithischian family Hadrosauridae. This group is known as the duck-billed dinosaurs for the flat duck-bill appearance of the bones in their snouts.
Hadrosauroidea is a clade or superfamily of ornithischian dinosaurs that includes the "duck-billed" dinosaurs, or Hadrosauridae, and all dinosaurs more closely related to them than to Iguanodon. Their remains have been recovered in Asia, Europe, Africa and the Americas.
Hadrosaurus (/ ˌ h æ d r ə ˈ s ɔːr ə s /; lit. ' bulky lizard ') is a genus of hadrosaurid ornithopod dinosaurs that lived in North America during the Late Cretaceous Period in what is now the Woodbury Formation in New Jersey about 83.6 to 77.9 Ma.
Didanodon altidens was followed as a genus of hadrosaurid by Canadian palaeontologist Loris S. Russell in 1930, who suggested that it may be the same genus as the taxon "Procheneosaurus" also from the DPF in Alberta. [3]

These are typical hadrosaurid traits and were concluded to have been acquired separately by the Hadrosauridae in a process of parallel evolution. Gobihadros differs from Bactrosaurus johnsoni , Probactrosaurus gobiensis , Eolambia caroljonesa , Claosaurus agilis and Tethyshadros insularis by an undulating upper profile of the ilium and a more ...
Weishampel and Horner found the Hadrosauridae to be a natural group after all. [10] They also found cladistic support for the traditional division of Hadrosauridae into the subfamilies Hadrosaurinae and Lambeosaurinae. [10] Weishampel reported the presence of hadrosaurs on the Antarctic peninsula. [15] [clarification needed] 1991
