Ecomorfología y evolución del aparato volador aviano: Implicaciones aerodinámicas en el vuelo de las aves basales
(Servicio de Publicaciones y Divulgación Científica, 2015)El descubrimiento de gran cantidad de fósiles de Aves de la era Mesozoica en los últimos años, está permitiendo un avance importante en el conocimiento de numerosos aspectos paleobiológicos de estas aves extintas y de los ... -
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 ... -
Geometric morphometrics shows differences and similarities in skull shape between the red and giant pandas.
Serrano Alarcón, Francisco José; Palmqvist-Barrena, Carlos Paul; Figueirido-Castillo, Francisco Borja (Wiley, 2011)
A morphometric analysis of the skull of the red or lesser panda, Aiulurus fulgens (Ailuridae), and the giant panda, Ailuropoda melanoleuca (Ursidae), was performed for evaluating the importance of natural selection and ... -
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 ... -
Morphological Disparity of the Humerus in Modern Birds
Serrano Alarcón, Francisco José; Costa-Pérez, Mireia; Navalón, Guillermo; Martín-Serra, Alberto (MDPI, 2020-05)
From a functional standpoint, the humerus is a key element in the skeleton of vertebrates as it is the forelimb's bone that connects with the pectoral girdle. In most birds, the humerus receives both the forces exerted by ... -
Multivariate analysis of neognath skeletal measurements: Implications for body mass estimation in Mesozoic birds
In this article, single and multiple regression functions based on osteological measurements were obtained from a large data set of extant flying birds for estimating the body mass of 42 Mesozoic specimens from stem taxa ... -
Shape at the cross-roads: Homoplasy and history in the evolution of the carnivoran skull towards herbivory
Serrano Alarcón, Francisco José; Figueirido-Castillo, Francisco Borja; Slater, Graham; Palmqvist-Barrena, Carlos Paul (Wiley, 2010-12)
Patterns of skull shape in Carnivora provide examples of parallel and convergent evolution for similar ecomorphological adaptations. However, although most researchers report on skull homoplasies among hypercarnivorous ...
