Molecular development of fibular reduction in birds and its evolution from dinosaurs
(WILEY-BLACKWELL, 2016)
Birds have a distally reduced, splinter-like fibula that is shorter than the tibia. In embryonic development, both skeletal elements start out with similar lengths. We examined molecular markers of cartilage differentiation ...
A large accumulation of avian eggs from the Late Cretaceous of Patagonia (Argentina) reveals a novel nesting strategy in Mesozoic birds
(Public Library Of Science, 2013-01)
We report the first evidence for a nesting colony of Mesozoic birds on Gondwana: a fossil accumulation in Late Cretaceous rocks mapped and collected from within the campus of the National University of Comahue, Neuquén ...
Dental replacement in Mesozoic birds: evidence from newly discovered Brazilian enantiornithines
(Nature, 2021-09)
Polyphyodonty—multiple tooth generations—in Mesozoic birds has been confirmed since the nineteenth century. Their dental cycle had been assessed through sparse data from tooth roots revealed through broken jawbones and ...
The higher-level phylogeny of Archosauria (Tetrapoda: Diapsida)
(TAYLOR & FRANCIS LTD, 2010)
Crown group Archosauria, which includes birds, dinosaurs, crocodylomorphs, and several extinct Mesozoic groups, is a primary division of the vertebrate tree of life. However, the higher-level phylogenetic relationships ...
Fossil evidence of the avian vocal organ from the Mesozoic
(Nature Publishing Group, 2016-10)
From complex songs to simple honks, birds produce sounds using a unique vocal organ called the syrinx. Located close to the heart at the tracheobronchial junction, vocal folds or membranes attached to modified mineralized ...

A carpometacarpus from the upper cretaceous of patagonia sheds light on the Ornithurine bird radiation
(Springer Heidelberg, 2012-03)
We report the discovery of an isolated avian carpometacarpus from the Upper Cretaceous Allen Formation (Campanian-Maastrichtian), Salitral Moreno, Río Negro Province, Argentina. This specimen is referred to cf. Neornithes ...
The first fossil avian egg from Brazil
(Taylor & Francis Ltd, 2014-10-02)
Marsola, J.C.A., Grellet-Tinner, G., Montefeltro, F.C., SayAo, J.M., Hsiou, A.S. & Langer, M.C., 2014. The first fossil avian egg from Brazil. Alcheringa 38, 563-567. ISSN 0311-5518.In contrast to the rich record of eggs ...
Rapid Initial Morphospace Expansion and Delayed Morphological Disparity Peak in the First 100 Million Years of the Archosauromorph Evolutionary Radiation
(Frontiers Media, 2021-09)
Adaptive radiations have played a major role in generating modern and deep-time biodiversity. The Triassic radiation of the Archosauromorpha was one of the most spectacular vertebrate radiations, giving rise to many highly ...
