Background: Tyrannosaurus rex was one of the largest terrestrial carnivores of all time, and consequently its ecology and diet have been the focus of much discussion. However, there is little direct evidence of diet or feeding habits in this species. Methodology/Principal Findings: Examination...

Dinosaur speed demon: the caudal musculature of Carnotaurus sastrei and implications for the evolution of South American abelisaurids
Download2011
Currie, P. J., Persons IV, W. S.
In the South American abelisaurids Carnotaurus sastrei, Aucasaurus garridoi, and, to a lesser extent Skorpiovenator bustingorryi, the anterior caudal ribs project at a high dorsolateral inclination and have interlocking lateral tips. This unique morphology facilitated the expansion of the caudal...

Vickaryous, M. K., Currie, P. J., Koppelhus, E. V., Sissons, R., Badamgarav, D.
Structure of the manus and pes has long been a source of confusion in ankylosaurs, owing to the imperfect preservation or complete lack of these parts of the skeletons in most specimens, and the fact that many species appear to have undergone a reduction in numbers of digits and phalanges. New...

Xing, L., Ji, S., Persons, W. S., Bell, P. R., Ji, Q., Miyashita, T., Currie, P. J., Burns, M. E.
Two skeletons of the large compsognathid Sinocalliopteryx gigas include intact abdominal contents. Both specimens come from the Jianshangou Beds of the lower Yixian Formation (Neocomian), Liaoning, China. The holotype of S. gigas preserves a partial dromaeosaurid leg in the abdominal cavity, here...

We describe a number of newly discovered dinosaur tracks from the Late Jurassic-Early Cretaceous Tuchengzi Formation, located in the core zone of Yanqing Silicified Wood National Geopark, during field work for the preparation of global geopark application in Yanqing County, Beijing. The...

Fanti, F., Currie, P. J., Badamgarav, D.
Two new specimens of the oviraptorid theropod Nemegtomaia barsboldi from the Nemegt Basin of southern Mongolia are described. Specimen MPC-D 107/15 was collected from the upper beds of the Baruungoyot Formation (Campanian-Maastrichtian), and is a nest of eggs with the skeleton of the assumed...

Analyzing taphonomic deformation of ankylosaur skulls using retrodeformation and finite element analysis
Download2012
Taphonomic deformation can make the interpretation of vertebrate fossil morphology difficult. The effects of taphonomic deformation are investigated in two ankylosaurid dinosaur taxa, Euoplocephalus tutus (to investigate effects on our understanding of intraspecific variation) and Minotaurasaurus...

Lech-Hernes, N. L., Currie, P. J., Arbour, V. M., Hurum, J. H., Guldberg, T. E.
A Mongolian ankylosaurid specimen identified as Tarchia gigantea is an articulated skeleton including dorsal ribs, the sacrum, a nearly complete caudal series, and in situ osteoderms. The tail is the longest complete tail of any known ankylosaurid. Remarkably, the specimen is also the first...
