Avialan status for Oviraptorosauria

open access: yes, 2002
Oviraptorosauria is a clade of Cretaceous theropod dinosaurs of uncertain affinities within Maniraptoriformes. All previous phylogenetic analyses placed oviraptorosaurs outside a close relationship to birds (Avialae), recognizing Dromaeosauridae or ...

The Phylocode: Beating a dead horse? - Discussion

open access: yes, 2007
The concept of the Phylocode has been evolving for some twenty years, and is supported by Lee and Skinner (2007): 1 argue against it here. The first issue is stability, and biologists must decide whether they seek rigidity (Phylocode) or flexibility and ...

The multiple origins of powered flight among paravian theropod dinosaurs: constraints from new phylogenetic, aerodynamic and anatomical data

open access: yes, 2017
The evolution of birds (Avialae) from paravian theropods is a textbook evolutionary radiation. Our understanding of this transition has been frustrated, however, by lack of consensus on the relationships between birds and their closest relatives.

Multiple origins of powered flight among paravian theropod dinosaurs: constraints from new phylogenetic, aerodynamic and anatomical data

open access: yes, 2018
The evolution of birds from paravian theropod dinosaurs is a classic evolutionary radiation. Unfortunately, there is a lack of consensus on the geneology of birds and their very closest relatives.
