Late Cretaceous neornithine from Europe illuminates the origins of crown birds
A newly discovered fossil from the Cretaceous of Belgium is the oldest modern bird ever found, showing a unique combination of features and suggesting attributes shared by avian survivors of the end-Cretaceous mass extinction.
Ecological selectivity and the evolution of mammalian substrate preference across the K–Pg boundary
Abstract The Cretaceous–Paleogene (K–Pg) mass extinction 66 million years ago was characterized by a worldwide ecological catastrophe and rapid species turnover. Large‐scale devastation of forested
Timing the extant avian radiation: The rise of modern birds, and the importance of modeling molecular rate variation
How relationships between life-history and substitution rates can mislead divergence time studies that do not account for directional changes in substitution rates over time is discussed, and it is suggested that these effects might have caused some of the variation in existing molecular date estimates for birds.
Evolution and dispersal of snakes across the Cretaceous-Paleogene mass extinction
An extensive molecular dataset is combined with phylogenetically and stratigraphically constrained fossil calibrations to infer an evolutionary timescale for Serpentes, revealing a potential diversification among crown snakes associated with the K-Pg mass extinction.
A North American stem turaco, and the complex biogeographic history of modern birds
P phylogenetic analyses support the enigmatic fossil bird Foro panarium Olson 1992 from the early Eocene (Wasatchian) of Wyoming as a stem turaco (Neornithes: Pan-Musophagidae), a clade that is presently endemic to sub-Saharan Africa.
So Volcanoes Created the Dinosaurs? A Quantitative Characterization of the Early Evolution of Terrestrial Pan-Aves
The early Mesozoic is marked by several global-scale environmental events, including the emplacement of large igneous provinces, such as the Siberian Traps, Wrangellia, and Central Atlantic Magmatic
Quantitative Analysis of Morphometric Data of Pre-modern Birds: Phylogenetic Versus Ecological Signal
The results indicate that while some ecological classes of modern birds can be discriminated from each other, phylogenetic signature can overwhelm ecological signal in morphometric data, potentially limiting the inferences that can be made from ecomorphological studies.
Exceptional continental record of biotic recovery after the Cretaceous–Paleogene mass extinction
A time-calibrated stratigraphic section in Colorado is reported that contains unusually complete fossils of mammals, reptiles, and plants and elucidates the drivers and tempo of biotic recovery during the poorly known first million years after the Cretaceous–Paleogene mass extinction.
Deep time diversity and the early radiations of birds
Three distinct large-scale increases in the diversification rate across bird evolutionary history are revealed, indicating that the bird biodiversity evolution was influenced mainly by long-term climatic changes and also by major paleobiological events such as the Cretaceous–Paleogene extinction.
The patterns and modes of the evolution of disparity in Mesozoic birds
A comparative phylogenetic study of the patterns and modes of Mesozoic bird skeletal morphology and limb proportions suggests that diversification of enantiornithines was characterized in exhausting fine morphologies, whereas ornithuromorphs continuously explored a broader array of morphologies and ecological opportunities.


Mass extinction of birds at the Cretaceous–Paleogene (K–Pg) boundary
A diverse avifauna from the latest Maastrichtian of western North America is described, which provides definitive evidence for the persistence of a range of archaic birds to within 300,000 y of the K–Pg boundary and shows that a major radiation of Ornithurae preceded the end of the Cretaceous.
Early Paleocene landbird supports rapid phylogenetic and morphological diversification of crown birds after the K–Pg mass extinction
The discovery of Tsidiiyazhi pushes the minimum divergence ages of as many as nine additional major neoavian lineages into the earliest Paleocene, compressing the duration of the proposed explosive post–K–Pg radiation of modern birds into a very narrow temporal window parallel to that suggested for placental mammals.
A new time tree reveals Earth history’s imprint on the evolution of modern birds
P pervasive evidence is found that avian evolution has been influenced by plate tectonics and environmental change, two basic features of Earth’s dynamics.
Phylogenomics reveals rapid, simultaneous diversification of three major clades of Gondwanan frogs at the Cretaceous–Paleogene boundary
It is found that ∼88% of living frogs originated from three principal lineages that arose at the end of the Mesozoic, coincident with the Cretaceous–Paleogene mass extinction event that decimated nonavian dinosaurs 66 Mya.
The extinction of the dinosaurs
The abruptness of the dinosaur extinction suggests a key role for the bolide impact, although the coarseness of the fossil record makes testing the effects of Deccan volcanism difficult.
