Aerodynamic modelling of a Cretaceous bird reveals thermal soaring capabilities during early avian evolution
(2017-07)Several flight modes are thought to have evolved during the early evolution of birds. Here, we use a combination of computational modelling and morphofunctional analyses to infer the flight properties of the raven-sized, ... -
Evolution of axial regionalization in Aves during the Mesozoic and its impact on the survival of modern lineages to K/Pgmass extinction
Serrano Alarcón, Francisco José; Pérez-Ramos, Alejandro; Chiappe, Luis M.; Chapman, Susan; Rashid, Dana J.; Bertrand, Ornella; Marcé-Nogué, Jordi; Brusatte, Steve; Figueirido-Castillo, Francisco Borja
[et al.] (2023)
The axial column of Neornithes (modern birds) is characterized by regional fusions in caudal vertebrae (pygostyle), lumbosacrals (synsacrum), and thoracics (notarium in several taxa) that provide a rigid and stable axis ... -
Flight reconstruction of two European enantiornithines (Aves, Pygostylia) and the achievement of bounding flight in Early Cretaceous birds
Serrano, Francisco José; Chiappe, Luis M.; Palmqvist-Barrena, Carlos Paul; Figueirido-Castillo, Francisco Borja; Marugán-Lobón, Jesús; Sanz, José L.[et al.] (Wiley, 2018-05)
Intermittent flight through flap-gliding (alternating flapping phases and gliding phases with spread wings) or bounding (flapping and ballistic phases with wings folded against the body) are strategies to optimize aerial ... -
Independent origins for powered flight in paravian dinosaurs?
(Cell Press, 2021)Feathered dinosaurs discovered during the last decades have illuminated the transition from land to air in these animals, underscoring a significant degree of experimentation in wing-assisted locomotion around the origin ... -
Inferring flight parameters of Mesozoic avians through multivariate analyses of forelimb elements in their living relatives
Serrano Alarcón, Francisco José; Palmqvist-Barrena, Carlos Paul; Chiappe, Luis M.; Sanz, José L. (Cambridge University Press, 2017-02)
Our knowledge of the diversity, ecology, and phylogeny of Mesozoic birds has increased significantly during recent decades, yet our understanding of their flight competence remains poor. Wing loading (WL) and aspect ratio ... -
Laser-stimulated fluorescence refines flight modeling of the early cretaceous bird sapeornis.
(American Museum of Natural History, 2020-08-21)Unseen and difficult-to-see soft tissues of fossil birds revealed by laser-stimulated fluorescence (LSF) shed light on their functional morphology. Here we study a well-preserved specimen of the early pygostylian Sapeornis ... -
The effect of long-term atmospheric changes on the macroevolution of birds.
Serrano, Francisco José; Chiappe, Luis M.; Palmqvist-Barrena, Carlos Paul; Figueirido-Castillo, Francisco Borja; Long, John; Sanz, José Luis[et al.] (Elsevier, 2019)
Atmospheric conditions are critical for a range of biological functions—locomotion among others—and long-term changes in these conditions have been identified as causal for different macroevolutionary patterns. Here we ...
