Gradual assembly of avian body plan culminated in rapid rates of evolution across the dinosaur-bird transition
The evolution of birds from theropod dinosaurs was one of the great evolutionary transitions
in the history of life [1–22]. The macroevolutionary tempo and mode of this transition is …

The shapes of bird beaks are highly controlled by nondietary factors
JA Bright, J Marugán-Lobón… - Proceedings of the …, 2016 - National Acad Sciences
Bird beaks are textbook examples of ecological adaptation to diet, but their shapes are also
controlled by genetic and developmental histories. To test the effects of these factors on the …

[HTML][HTML] Potential for powered flight neared by most close avialan relatives, but few crossed its thresholds
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 …

A new giant titanosaur sheds light on body mass evolution among sauropod dinosaurs
Titanosauria was the most diverse and successful lineage of sauropod dinosaurs. This clade
had its major radiation during the middle Early Cretaceous and survived up to the end of that …
