A nearly identical EQ range of 2.3 to 3.8 was found, and it was again noted this was higher than that of living reptiles, sauropods and other ornithischians, but different EQ estimates for theropods were cited, placing the hadrosaur numbers significantly below even more basal theropods like Ceratosaurus (with an EQ range of 3.31 to 5.07) and ...
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.
†Hadrosauridae Hadrosauromorpha is a clade of iguanodontian ornithopods , defined in 2014 by David B. Norman to divide Hadrosauroidea into the basal taxa with compressed manual bones and a pollex , and the derived taxa that lack them.
Saurolophus (/ s ɔː ˈ r ɒ l ə f ə s /; meaning "lizard crest") is a genus of large hadrosaurid dinosaur from the Late Cretaceous period of Asia and North America, that lived in what is now the Horseshoe Canyon and Nemegt formations about 70 million to 66 million years ago.
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.
Restoration. Barsboldia was a large hadrosaur, previously estimated at 10 metres (33 ft) in length and 5 metric tons (5.5 short tons) in body mass. [2] In 2011, the tibial length was measured at 1.4 m (4.6 ft), rivaling that of Shantungosaurus at 1.47 m (4.8 ft) and that of Magnapaulia at 1.36 m (4.5 ft); this indicates that Barsboldia could have possibly reached within the range of 12–14 ...
Protohadros (meaning "first hadrosaur") is a genus of herbivorous ornithischian dinosaur from the Late Cretaceous (Cenomanian stage).. Gary Byrd, a part-time palaeontologist, discovered some remains of this euornithopod (ribs and an ungual) during early 1994 at Flower Mound, Denton County, north-central Texas.
Ajnabia (meaning "stranger" or "foreigner") is a genus of lambeosaurine hadrosaur from the Late Cretaceous (Maastrichtian) of Morocco. It is the first definitive hadrosaur from Africa, and is thought to be related to European hadrosaurs like Arenysaurus. [1]
