British plated dinosaurs (Ornithischia, Stegosauridae)
Journal of Vertebrate Paleontology, 1985ABSTRACT All specimens of the Stegosauridae from England are described. The material from the lower and upper Bathonian (Middle Jurassic) of Oxfordshire and Gloucestershire is the earliest record of the family. The holotype femur of Omosaurus vetustus Huene is tentatively referred to the genus Lexovisaurus Hoffstetter as L.?

Adaptive features of protoceratopoids (Ornithischia: Neoceratopsia)
Paleontological Journal, 2008The analysis of some morphological characteristics of protoceratopoid skeletons, the extent of mobility of the vertebral column, and the probable adaptive significance of these features suggest that Bagaceratops had a mostly aquatic mode of life, Protoceratops was semiaquatic, Udanoceratops was facultatively aquatic, and Leptoceratops was predominantly

AN OSSIFIED TENDON TRELLIS IN CHASMOSAURUS (ORNITHISCHIA: CERATOPSIDAE)
Journal of Paleontology, 2007The ornithischia and its sister group, the Saurischia, comprise the Dinosauria. Ornithischians (Weishampel, 2004) are a diverse group of primarily quadrupedal herbivores that include such familiar dinosaurs as the armored stegosaurs and ankylosaurs (Thyreophora), as well as the duckbilled hadrosaurs, pachycephalosaurs, and ceratopsians (Cerapoda).

A nest ofProtoceratops andrewsi(Dinosauria, Ornithischia)
Journal of Paleontology, 2011A remarkable specimen of the small neoceratopsian dinosaurProtoceratops andrewsi(Late Cretaceous, Mongolia) reveals the first nest of this genus, complete with fifteen juveniles. The relatively large size of the individuals and their advanced state of development suggests the possibility thatProtoceratopsjuveniles remained and grew in their nests ...

A review of pelvic shield morphology in ankylosaurs (Dinosauria: Ornithischia)
Journal of Paleontology, 2011The pelvic shield of ankylosaurian dinosaurs refers to an area of osteoderms lacking differentiated transverse bands over the pelvic region and it is used as a diagnostic character for various ankylosaur groups. The pelvic shield character varies across ankylosaur taxa but is typically coded as a binary character or is excluded from phylogenetic ...

The Palatal Structure of some Canadian Hadrosauridae (Reptilia: Ornithischia)
Canadian Journal of Earth Sciences, 1972Two distinct hadrosaurian lineages can be delineated, each showing changes from possible hypsilophodont ancestors. The Hadrosaurinae are typified by moderately vaulted palates, broad pterygoid flanges, large anterior maxillary processes, and non-folded premaxillae, with direct narial passages.
