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.
This clade excludes basal hadrosaurids such as Hadrosaurus and Yamatosaurus but self-destructs if Hadrosaurus is descended from the last common ancestor of Lambeosaurus and Saurolophus. [21] Premaxilla of Eotrachodon, the taxon named by Prieto-Marquez et al. 2016. Below is a cladogram from Prieto-Marquez et al. 2016. This cladogram is a recent ...
The discovery was not formally described until 1994 where it was identified as the femur of a small hadrosaur or iguanodontid, probably the former. [3] The first report of a dinosaur from Central America ever however was a newspaper article published in August of 1933 by Canada's Montreal Gazette , though the story was picked up by several ...
Dubious name for a species of tyrannosauroid from New Jersey, possibly a Dryptosaurus or a potentially new genus. Dryptosaurus: Upper Cretaceous: carnivore: Medium-sized tyrannosauroid from New Jersey. It was the first theropod unearthed in North America. Eotrachodon: Upper Cretaceous: herbivore: Hadrosaur from Alabama known from a nearly ...
Hadrosauroidea was given a formal phylogenetic definition in the PhyloCode by Daniel Madzia and colleagues in 2021 as "the largest clade containing Hadrosaurus foulkii, but not Iguanodon bernissartensis". [1] The cladogram below follows an analysis by Andrew McDonald, 2012, and shows the position of Hadrosauroidea within Styracosterna: [2]
Spectacular fossils of hadrosaurs have been found, including mummified specimens in which soft tissue was preserved, skin impressions, tracks of footprints, and nest sites that demonstrate the animals had parental care of offspring. Animals are shown to scale. Reason
This list of nicknamed dinosaur fossils is a list of fossil non-avian dinosaur specimens given informal names or nicknames, in addition to their institutional catalogue numbers. It excludes informal appellations that are purely descriptive (e.g., "the Fighting Dinosaurs", "the Trachodon Mummy").
