Conditions of paravian morphology for aerial performance are evaluated by quantifying static stability and control effectiveness of physical models for numerous taxa sampled from within the lineage leading to birds (Paraves).
Early dinosaurs: A phylogenetic study
A new cladistic analysis of the early dinosaur radiation was performed to assess the relationships among the three major clades (Ornithischia, Sauropodomorpha and Theropoda) and to define the phylogenetic position of the basal members of the group.
The origin of the avian flight stroke: a kinematic and kinetic perspective
This work introduces six kinetic components that interact to determine a limb's trajectory and offers four specific criteria to help constrain and evaluate competing scenarios for the origin of the avian flight stroke.
Do feathered dinosaurs exist? Testing the hypothesis on neontological and paleontological evidence
It is suggested that Aves plus bird‐like maniraptoran theropods (e.g., microraptors and others) may be a separate clade, distinctive from the main lineage of Theropoda, a remnant of the early avian radiation, exhibiting all stages of flight and flightlessness.
The origin and early evolution of birds: discoveries, disputes, and perspectives from fossil evidence

Significant size and morphological differences and variation in flight capabilities, ranging from gliding to powerful flight among early birds, highlight the diversification of birds in the Early Cretaceous.
Phylogenetic Context for the Origin of Feathers1
Current evidence strongly suggests that birds are theropod dinosaurs, and that the most primitive known feathers are found on non-flying animals, which suggests that feathers did not evolve as flight structures.
The assembly of the avian body plan : a 160-million-year long process
Birds are one of the most successful groups of vertebrates. The origin of birds from their reptilian ancestors is traditionally rooted near the Jurassic “Urvogel” Archaeopteryx, an approach that has
The Anatomy of Teleocrater rhadinus, an Early Avemetatarsalian from the Lower Portion of the Lifua Member of the Manda Beds (Middle Triassic)
ABSTRACT Bird-line archosaurs (= Avemetatarsalia, the clade containing birds, dinosaurs, pterosaurs, and their kin) originated in the Triassic Period. However, the earliest evolution of this group is
A Norian Lagerpetid Dinosauromorph from the Quebrada Del Barro Formation, Northwestern Argentina
A phylogenetic analysis recovers Dromomerson gigas nested into the monophyletic group Lagerpetidae, and as the sister taxon to Dromomeron romeri, suggesting that body size increased in this lineage over time, as was previously demonstrated for Dinosauriformes as a whole, and that lagerpetids reached a larger size than previously thought.
Shifts in stability and control effectiveness during evolution of Paraves support aerial maneuvering hypotheses for flight origins
Results of aerodynamic testing are mapped phylogenetically to examine how maneuvering characteristics correspond to tail shortening, forewing elaboration, and other morphological features, and suggest features normally considered in light of development of a power stroke may play important roles in control.
