Data from: Flight reconstruction of two European enantiornithines (Aves, Pygostylia) and the achievement of bounding flight in Early Cretaceous birdsFrancisco J. Serrano, Luis M. Chiappe, Paul Palmqvist, Borja Figueirido, Jesús Marugán-Lobón & José L. Sanz
Birds today follow different aerial strategies to deal with the high costs of flapping flight. Intermittent flight, through either flap-gliding or bounding, is commonly used among small birds as a strategy to optimize aerial efficiency. The broad morphological disparity of the different lineages of Mesozoic birds suggests that a range of aerial strategies could have evolved early in avian evolution. Based on biomechanics and aerodynamic theory, this study reconstructs the flying properties of two small...
Data from: Quantifying the dark data in museum fossil collections as palaeontology undergoes a second digital revolutionCharles R. Marshall, Seth Finnegan, Erica C. Clites, Patricia A. Holroyd, Nicole Bonuso, Crystal Cortez, Edward Davis, Gregory P. Dietl, Patrick S. Druckenmiller, Ron C. Eng, Christine Garcia, Kathryn Estes-Smargiassi, Austin Hendy, Kathy A. Hollis, Holly Little, Elizabeth A. Nesbitt, Peter Roopnarine, Leslie Skibinski, Jann Vendetti & Lisa D. White
Large-scale analysis of the fossil record requires aggregation of palaeontological data from individual fossil localities. Prior to computers these synoptic datasets were compiled by hand, a laborious undertaking that took years of effort and forced palaeontologists to make difficult choices about what types of data to tabulate. The advent of desktop computers ushered in palaeontology’s first digital revolution – online literature-based databases, such as the Paleobiology Database (PBDB). However, the published literature represents only a...
Data from: Genome-wide SNP markers breathe new life into phylogeography and species delimitation for the problematic short-necked turtles (Chelidae: Emydura) of eastern AustraliaArthur Georges, Bernd Gruber, Greg B. Pauly, Duanne White, Mark Adams, Matthew J. Young, Andzrej Kilian, Xiuwen Zhang, H. Bradley Shaffer, Peter J. Unmack & Andrzej Kilian
Understanding the evolutionary history of diversifying lineages and the delineation of evolutionarily significant units and species remain major challenges for evolutionary biology. Low cost representational sampling of the genome for single nucleotide polymorphisms (SNPs) shows great potential at the temporal scales that are typically the focus of species delimitation and phylogeography. We apply these markers to a case study of a freshwater turtle, Emydura macquarii, whose systematics has so far defied resolution, to bring to...
The Cretaceous–Palaeogene (K–Pg) mass extinction is linked to the rapid emergence of ecologically divergent higher taxa (for example, families and orders) across terrestrial vertebrates, but its impact on the diversification of marine vertebrates is less clear. Spiny-rayed fishes (Acanthomorpha) provide an ideal system for exploring the effects of the K–Pg on fish diversification, yet despite decades of morphological and molecular phylogenetic efforts, resolution of both early diverging lineages and enormously diverse subclades remains problematic. Recent...
Data from: The evolutionary relationship between beak shape, mechanical advantage, and feeding ecology in modern birdsGuillermo Navalón, Jen A. Bright, Jesús Marugán-Lobón & Emily J. Rayfield
Extensive research on avian adaptive radiations has led to a presumption that beak morphology predicts feeding ecology in birds. However, this ecomorphological relationship has only been quantified in a handful of avian lineages, where associations are of variable strength, and never at a broad macroevolutionary scale. Here, we used shape analysis and phylogenetic comparative methods to quantify the relationships between beak shape, mechanical advantage, and two measures of feeding ecology (feeding behaviour and semi-quantitative dietary...
