- 17 August 2012
This study provides the most detailed and comprehensive phylogenetic analysis of paravians to date in order to explore the phylogenetic history of dromaeosaurid taxa and reviews and revises the membership of DromaeOSauridae and provides an apomorphy-based diagnosis for all valid taxa.

- 13 October 2005
A near-complete, small dromaeosaurid is described that is both the most complete and the earliest member of the Maniraptora from South America and which provides new evidence for a unique Gondwanan lineage of DromaeOSauridae with an origin predating the separation between northern and southern landmasses.
Osteology of Cryolophosaurus ellioti (Dinosauria: Theropoda) from the Early Jurassic of Antarctica and implications for early theropod evolution
- N. Smith, P. Makovicky, W. R. Hammer, P. Currie
- Environmental Science, Geography
- 1 October 2007
An in-depth morphological description of Cryolophosaurus is pre-sented here, along with a rigorous phylogenetic analysis of theropod relationships consisting of 347 characters and 56 taxa, in an attempt to clarify the relationships of Crylophosaurus and to provide insight into questions sur-rounding early theropid evolution.

The discovery of Sinovenator and the examination of character distributions along the maniraptoran lineage indicate that principal structural modifications toward avians were acquired in the early stages of manIRaptoran evolution.
Important Features of the Dromaeosaurid Skeleton II : Information from Newly Collected Specimens of Velociraptor mongoliensis
- P. Makovicky
- Biology
This description concentrates on poorly known aspects of the skeleton of Velociraptor mongoliensis, including several features that are extremely similar to characters found in basal avialans like Archaeopteryx lithographica.
Gigantism and comparative life-history parameters of tyrannosaurid dinosaurs

- 12 August 2004
Growth patterns within the Tyrannosauridae are studied and it is determined that Tyrannosaurus rex's great stature was primarily attained by accelerating growth rates beyond that of its closest relatives.
Osteology and Relationships of Byronosaurus jaffei (Theropoda: Troodontidae)
- P. Makovicky, M. Norell, James M. Clark, T. Rowe
- Environmental Science, Geography
- 1 March 2003
Several interesting characters of Byronosaurus jaffei have implications both for theropod relationships and for understanding patterns of variation within coelurosaurian theropods.
Tyrannosaur Paleobiology: New Research on Ancient Exemplar Organisms
- S. Brusatte, M. Norell, Xing Xu
- Environmental Science, GeographyScience
- 17 September 2010
The biology and evolutionary history of tyrannosaurs are reviewed and their phylogenetic relations are updated to include several new fossils, showing that tyrannosaurs originated by the Middle Jurassic but remained mostly small and ecologically marginal until the latest Cretaceous.
An Early Ostrich Dinosaur and Implications for Ornithomimosaur Phylogeny
- Q. Ji, M. Norell, P. Makovicky, K. Gao, S. Ji, Chong-xi Yuan
- Environmental Science, Geography
- 2003
A new ornithomimosaur from the Yixian Formation of Liaoning Province People's Republic of China is described and this taxon is placed in a phylogenetic analysis of Coelurosauria and shown to be near the base of the ornithological clade.
A New Dromaeosaurid Theropod from Ukhaa Tolgod (Ömnögov, Mongolia)
- P. Makovicky, M. Norell
- Geography
- 7 December 2006
A new dromaeosaurid theropod from the Upper Cretaceous Djadokhta Formation of Ukhaa Tolgod, Mongolia is described, with a well-preserved skull and cervical series and a jugal–squamosal contact that excludes the postorbital from the margin of the infratemporal fenestra.
