A ceratopsian dinosaur from China and the early evolution of Ceratopsia
Nature, 2002Ceratopsians (horned dinosaurs) represent one of the last and the most diverse radiations of non-avian dinosaurs. Although recent systematic work unanimously supports a basal division of Ceratopsia into parrot-like psittacosaurids and frilled neoceratopsians, the early evolution of the group remains poorly understood, mainly owing to its incomplete ...

Jaw Mechanics in Basal Ceratopsia (Ornithischia, Dinosauria) [PDF]
Anatomical Record, 2009 AbstractCeratopsian dinosaurs were a dominant group of herbivores in Cretaceous terrestrial ecosystems. We hypothesize that an understanding of the feeding system will provide important insight into the evolutionary success of these animals. The mandibular mechanics of eight genera of basal ceratopsians was examined to understand the variability in ...

Phylogenetic position of Turanoceratops (Dinosauria: Ceratopsia)
Naturwissenschaften, 2009Farke et al. (2009) commented on our recent paper describing new material of the Late Cretaceous ceratopsian dinosaur Turanoceratops from Uzbekistan (Sues and Averianov 2009). We provided evidence that Turanoceratops is the first member of the clade Ceratopsidae known outside North America. Farke et al.

Growth curve of Psittacosaurus mongoliensis Osborn (Ceratopsia: Psittacosauridae) inferred from long bone histology [PDF]
Zoological Journal of the Linnean Society, 2000 Abstract The skeleton undergoes substantial histological modification during ontogeny in association with longitudinal growth, shape changes, reproductive activity, and fatigue repair. This variation can hinder attempts to reconstruct life history attributes for individuals, particularly when only fossil materials are availble for study. Histological

Ceratopsia increase: history and trends
Canadian Journal of Earth Sciences, 2013The taxonomic history of the Ceratopsia began in 1876 with the description of Monoclonius crassus Cope followed in 1889 by Triceratops horridus Marsh. After a peak of discovery and description in the 1910s and 1920s resulting from the Canadian dinosaur rush in the province of Alberta and the Central Asiatic Expeditions to Mongolia of the American ...
