A new look at the phylogeny of coelurosauria (Dlnosauria: Theropoda)

Journal of Systematic Palaeontology, 2007
Synopsis The most comprehensive phylogenetic analysis of the theropod clade Coelurosauria to date, is presented here, with 85 coelurosaurian ingroups and 360 characters, using Allosaurus and Sinraptoras outgroups. The strict consensus tree is highly resolved and has the following topology: Tyrannosauroidea + (Compsognathidae + (Arctometatarsalia ...

Anatomy, systematics, and evolution of Oviraptorosauria (Dinosauria, Theropoda)

2019
Here I describe new oviraptorosaur specimens and add to our knowledge of the anatomy, growth, behaviour, ecology, and evolution of oviraptorosaurs. Oviraptorosaurs were a diverse group of theropods known from a long history of discovery and a relatively abundant fossil record. Most analyses divide the toothless members of the clade into three families:

Vitakridrinda (Vitakrisauridae, Theropoda) from the latest Cretaceous of Pakistan

Journal of Earth Science, 2010
The holotyic and referred specimens of the slender and large bodied Vitakridrinda sulaimani (Vitakrisauridae, Theropoda) were found in the latest Cretaceous Vitakri Formation of Sulaiman Basin, Balochistan, Pakistan. The holotypic fossil record of Vitakridrinda rostrum demonstrates the serious confrontation between theropods which resulted in the death
