Integumentary structures of ornithischain dinosaurs of the taxon Hypsilophodontia (Ornithopoda) from the Ukureiskaya Formation (Upper Jurassic) of the Kulinda locality (Transbaikal Region, Russia) are described in detail. It is shown that members of this group had so-called bristle scales, integumentary appendages previously unknown in ornithischian ...

The taxonomy of species assigned to Camptosaurus (Dinosauria: Ornithopoda)
Zootaxa, 2011The taxonomic affinities of species assigned to Camptosaurus are reassessed in light of firsthand examination of the relevant specimens and a new phylogenetic analysis, the first to incorporate all putative species of Camptosaurus. “Camp- tosaurus” valdensis is found to be an indeterminate dryosaurid. The species C. prestwichii, C. aphanoecetes, and C.

A new basal hadrosauroid (Dinosauria: Ornithopoda) from the Turonian of New Mexico
Journal of Vertebrate Paleontology, 2010ABSTRACT MSM P4166, a specimen from the Moreno Hill Formation (middle Turonian) of New Mexico, is described as the holotype of a new genus and species of hadrosauroid dinosaur. Jeyawati rugoculus, gen. et sp. nov., is diagnosed by a rugose texture that covers the entire lateral surface of the postorbital and the presence of a large neurovascular ...

Fabrosauridae, the basal family of ornithischian dinosaurs (Reptilia: Ornithopoda)
Paläontologische Zeitschrift, 1978In fabrosaurids the upper jaw is flat and the lower jaw is slender so the ’cheek’ teeth are marginal and not inset as is the case in all other ornithischian dinosaurs. The ’cheek’ teeth of fabrosaurids have anteroposteriorly expanded crowns but lack wear surfaces formed by tooth to tooth contact.

Cretaceous Research, 2017
Abstract At the end of nineteenth century, approximately thirty nearly complete skeletons of the ornithopod dinosaur Iguanodon bernissartensis were discovered in Lower Cretaceous deposits in Bernissart (Belgium). Because most of the specimens are approximately the same size, they offer a unique opportunity for studying individual variation (i.e ...

We describe a new genus and species of a basal iguanodontian ornithopod dinosaur, Pareisactus evrostos, from lower Maastrichtian strata of the Conques Formation in the south-central Pyrenees of northeastern Spain. This animal is solely represented by a scapula characterized by having a dorsoventral extent of the proximal constriction as deep as it is ...
