Growing Up Tyrannosaurus Rex: Osteohistology Refutes the Pygmy Nanotyrannus and Supports Ontogenetic Niche Partitioning in Juvenile Tyrannosaurus [PDF]
Despite its iconic status as the king of dinosaurs, Tyrannosaurus rex biology is incompletely understood. Here, we examine femur and tibia bone microstructure from two half-grown T.

Tooth enamel microstructure of Revueltosaurus and Krzyzanowskisaurus (Reptilia: Archosauria) from the Upper Triassic Chinle Group, USA: Implications for function, growth, and phylogeny [PDF]
Tooth enamel microstructure can carry significant phylogenetic, ontogenetic, and functional information within amniotes. Here we provide the first descriptions of the tooth enamel microstructure of two Late Triassic taxa, the crurotarsan Revueltosaurus ...

Visualising muscle anatomy using three-dimensional computer models - an example using the head and neck muscles of Sphenodon [PDF]
We demonstrate how the computer-based technique of multi-body dynamics analysis (MDA) can be used to create schematic, but informative three-dimensional (3D) representations of complex muscle anatomy.

Reassessment of the enigmatic Late Cretaceous theropod dinosaur, Bagaraatan ostromi [PDF]
The Late Cretaceous Bagaraatan ostromi, described by Osmólska in 1996, is one of the most enigmatic theropod dinosaurs. The holotype possesses a peculiar combination of features, which Osmólska suggested were indicative of a primitive position among ...
