New Data on Cranial Anatomy of the Ceratopsian Dinosaur Psittacosaurus major

  title={New Data on Cranial Anatomy of the Ceratopsian Dinosaur Psittacosaurus major},
  author={Hailu You and Kyo Tanoue and Peter Dodson},
An exceptionally preserved skull and mandible of ceratopsian dinosaur Psittacosaurus major revealed many anatomical details such as the existence of an elliptical median interpremaxillary foramen, a prominent neurovascular canal on the internal wall of the beak, long, slightly divergent basipterygoid processes developed as vertical blades with a deep cleft between them, and horizontally oriented vomer. The new specimen shows two autapomorphies of Psittacosaurus major, the transversely narrow… 
Comparative anatomy of selected basal ceratopsian dentitions
The dental structure of basal ceratopsians is described. Evolutionary trends in maxillary and dentary teeth of basal ceratopsians include decrease and possible loss of enamel on the occluding side of
The integument of Psittacosaurus from Liaoning Province, China: taphonomy, epidermal patterns and color of a ceratopsian dinosaur
The data here enable to reconstruct the colors of Psittacosaurus as predominantly black and amber/brown, in cryptic patterns, somewhat dull, but useful to a prey animal, and suggest that melanin was the dominant chemical involved in the coloration of PsITTacosaurus.
Ontogenetic braincase development in Psittacosaurus lujiatunensis (Dinosauria: Ceratopsia) using micro-computed tomography
Using reconstructions created from micro-computed tomography scans of well-preserved skulls from the Barremian–Aptian Yixian Formation, China, morphological changes in the braincase of Psittacosaurus lujiatunensis are document, providing the first detailed study of ceratopsian braincase morphology through ontogeny.
Jaw Mechanics in Basal Ceratopsia (Ornithischia, Dinosauria)
The results indicate that psittacosaurids had higher leverage at the beak and in the rostral part of the tooth row than basal neoceratopsians, but lower leverage in the caudal parts of the teeth, as is also true in ceratopsids.
Taxonomy, Cranial Morphology, and Relationships of Parrot-Beaked Dinosaurs (Ceratopsia: Psittacosaurus)
in 1922, well-preserved fossils of the first parrotbeaked dinosaur were discovered in Early Cretaceous horizons in the Gobi Desert of Mongolia. Now referred to a single species, Psittacosaurus
Psittacosaurus amitabha, a New Species of Ceratopsian Dinosaur from the Ondai Sayr Locality, Central Mongolia
This taxon expands the knowledge of the already-speciose genus Psittacosaurus as well as the understanding of the Ondai Sayr fauna, which is poorly known in comparison to other Mongolian Early Cretaceous localities.
Cranial Anatomy of the Small Ornithischian Dinosaur Changchunsaurus parvus from the Quantou Formation (Cretaceous: Aptian-Cenomanian) of Jilin Province, Northeastern China
ABSTRACT The Quantou Formation of Jilin Province, People's Republic of China, has recently yielded an important new fauna of ‘middle’ Cretaceous vertebrates. This fauna includes the small-bodied
A new psittacosaur from Inner Mongolia and the parrot-like structure and function of the psittacosaur skull
A novel isognathous jaw mechanism that combines aspects of arcilineal (vertical) and propalinal (horizontal) jaw movement is described that was able to maintain oblique shearing occlusion in an akinetic skull designed to resist high bite forces in psittacosaurs.
The osteology and taphonomy of a Psittacosaurus bonebed assemblage of the Yixian Formation (Lower Cretaceous), Liaoning, China
Abstract We present the first detailed description of the osteology and mineralogy of an assemblage of Psittacosaurus juveniles (DMNH D2156) associated with a larger specimen from the Lujiatun beds
A psittacosaurid-like basal neoceratopsian from the Upper Cretaceous of central China and its implications for basal ceratopsian evolution

An Adult Specimen of Hongshanosaurus houi (Dinosauria: Psittacosauridae) from the Lower Cretaceous of Western Liaoning Province, China
A new specimen consisting of a complete skull and lower jaw was discovered from the Lujiatun bed of the Lower Cretaceous Yixian Formation in the Lujiatun site, Beipiao, western Liaoning Province. It
Psittacosaurus meileyingensis (Ornithischia: Ceratopsia), a new psittacosaur from the Lower Cretaceous of northeastern China
ABSTRACT A new psittacosaur species, Psittacosaurus meileyingensis, is based on a well preserved skull with referred cranial and postcranial remains. The skull is tall relative to its length and has
A Ceratopsian dinosaur Psittacosaurus sibiricus from the Early Cretaceous of West Siberia, Russia and its phylogenetic relationships
The three lateral foramina on the exoc‐cipital/opisthotic are interpreted as exits for cranial nerves X+XI, XII1+2 and XII3, in contrast with previous interpretations.
A new species of Psittacosaurus (Dinosauria: Ceratopsia) from the Early Cretaceous Yixian Formation, Liaoning, China
Abstract Newly discovered, well-preserved skulls and mandibles from the lowest part of the Early Cretaceous Yixian Formation, western Liaoning Province, China, document the earliest known record of
On a New Genus of Basal Neoceratopsian Dinosaur from the Early Cretaceous of Gansu Province, China
A new genus and species of basal neoceratopsian dinosaur, Auroraceratops rugosus, is reported based on material from the Early Cretaceous Xinminpu Group in the Gongpoquan Basin of Gansu Province,
New psittacosaurid highlights skull enlargement in homed dinosaurs
The evolution of extraordinary absolute and relative skull size among ceratopsians appears to have been driven by sexual selection and involved the tandem evolution of reduced head mobility and an obligate quadrupedal posture.
New psittacosaur occurrences in Inner Mongolia
