New Siberian Ceratopsian

A ceratopsian dinosaur Psittacosaurus sibiricus from the Early Cretaceous of west Siberia, Russia and its phylogenetic relationships. 2006. A.O. Averianov, et al. J. Systematic Palaeo. 4: 359-395.

Abstract: Psittacosaurus sibiricus from the AptianAlbian Ilek Formation at Shestakovo, Kemerovo Province, West Siberia, is represented by two almost complete adult skeletons, several associated groups of bones and numerous isolated bones of individuals ranging from post-hatchling to fully grown animals.

Psittacosaurus sibiricus differs from nine other species of the genus by a unique combination of 32 diagnostic characters, six of which are autapomorphies of the species: small infratemporal fenestra, anteroposteriorly short premaxilla, short medial process of postorbital, deep cleft for qaudratojugal on jugal, extending to the posterior side of jugal horn, angular with prominent tuber and 23 presacrals.

Psittacosaurus sibiricus is the sister species of P. sinensis, with which it shares the prominent pyramidal laterally projecting jugal horn, but more derived than the latter in having more developed palpebral and postorbital horns.

  1. Skin-deep secret of dinos revealed

    LONDON: Scientists have been able to get an exceptional glimpse of what dinosaurs were like deep under the skin, thanks to a fossil unearthed in China.

    The fossil shows that the plant-eating Psittacosaurus had a thick layer of shark-like skin hidden under scales or feathers. Soft tissues such as skin are seldom conserved in the fossil record, thus leading to intense dispute over what dinosaurs looked like.

    The Psittacosaurus, or parrot lizard, specimen gives the first thorough depiction of what dinosaurs were like in the flesh. The tough outer coating supported the dinosaur’s organs and protected it from predators.

    Tooth marks on the fossil point out that the dinosaur was torn open by a scavenger, giving an exclusive insight into their biology, 100 million years after Psittacosaurus’ death.
