Pectoral Girdle Morphology in Early-Diverging Paravians and Living Ratites: Implications for the Origin of Flight
(American Museum of Natural History, 2020-08)
Discussions about the origin of flight almost unanimously assume that early birds positioned (and moved) their wings in the same basic manner as living flying birds, with reconstructed wings extended with the airfoil surface ...
New theropod dinosaur from the Upper Cretaceous of Patagonia sheds light on the paravian radiation in Gondwana
(Springer, 2020-06)
The fossil record of basal paravians in Gondwana is still poorly known, being limited to the Cretaceous unenlagiids from South America and the problematic Rahonavis from Madagascar. Here we report on a new paravian from ...
Comments on the morphology of basal paravian shoulder girdle: New data based on unenlagiid Theropods and Paleognath birds
(Frontiers Media, 2021-05)
In 1976 John Ostrom published an enlightening paper about the anatomical transformations in the shoulder girdle and forelimb elements along the origin of birds. Most of his ideas were based on comparing Archaeopteryx ...
Paravian phylogeny and the dinosaur-bird transition: An overview
(Frontiers Media S.A., 2019-02)
Recent years witnessed the discovery of a great diversity of early birds as well as closely related non-avian theropods, which modified previous conceptions about the origin of birds and their flight. We here present a ...
Potential for Powered Flight Neared by Most Close Avialan Relatives, but Few Crossed Its Thresholds
(Cell Press, 2020-10)
Uncertainties in the phylogeny of birds (Avialae) and their closest relatives have impeded deeper understanding of early theropod flight. To help address this, we produced an updated evolutionary hypothesis through an ...
