Data from: Probabilistic methods surpass parsimony when assessing clade support in phylogenetic analyses of discrete morphological data

Joseph E. O'Reilly, Mark N. Puttick, Davide Pisani & Philip C. J. Donoghue
Fossil taxa are critical to inferences of historical diversity and the origins of modern biodiversity, but realizing their evolutionary significance is contingent on restoring fossil species to their correct position within the tree of life. For most fossil species, morphology is the only source of data for phylogenetic inference; this has traditionally been analysed using parsimony, the predominance of which is currently challenged by the development of probabilistic models that achieve greater phylogenetic accuracy. Here,...

Data from: Impact of the Late Triassic mass extinction on functional diversity and composition of marine ecosystems

Alexander M. Dunhill, William J. Foster, James Sciberras & Richard J. Twitchett
Mass extinctions have profoundly influenced the history of life, not only through the death of species but also through changes in ecosystem function and structure. Importantly, these events allow us the opportunity to study ecological dynamics under levels of environmental stress for which there are no recent analogues. Here, we examine the impact and selectivity of the Late Triassic mass extinction event on the functional diversity and functional composition of the global marine ecosystem, and...

Data from: Pulmonary anatomy and a case of unilateral aplasia in a common snapping turtle (Chelydra serpentina): developmental perspectives on cryptodiran lungs

Emma R. Schachner, Jayc C. Sedlmayr, Renée Schott, Tyler R. Lyson, R. Kent Sanders & Markus Lambertz
The common snapping turtle (Chelydra serpentina) is a well studied and broadly distributed member of Testudines; however, very little is known concerning developmental anomalies and soft tissue pathologies of turtles and other reptiles. Here, we present an unusual case of unilateral pulmonary aplasia, asymmetrical carapacial kyphosis, and mild scoliosis in a live adult C. serpentina. The detailed three-dimensional (3D) anatomy of the respiratory system in both the pathological and normal adult C. serpentina, and a...

Data from: Evolutionary origins of teeth in jawed vertebrates: conflicting data from acanthothoracid dental plates (‘Placodermi’)

Moya Meredith Smith, Brett Clark, Daniel Goujet & Zerina Johanson
Placoderms (Devonian fossil fishes) are resolved phylogenetically to the base of jawed vertebrates and provide important evidence for evolutionary origins of teeth, particularly with respect to the Arthrodira. The arthrodires represent a derived group of placoderms; the dentition of other more primitive placoderms such as the acanthothoracids is less well known. Articulated acanthothoracid dental plates are rare; x-ray computed tomography of a single, unique specimen, along with 3D segmentation of bone, oral denticles and vascular...

Data from: Relative size predicts competitive outcome through 2 million years

Lee Hsiang Liow, Emanuela Di Martino, Malgorzata Krzeminska, Mali Ramsfjell, Seabourne Rust, Paul D. Taylor & Kjetil L. Voje
Competition is an important biotic interaction that influences survival and reproduction. While competition on ecological timescales has received great attention, little is known about competition on evolutionary timescales. Do competitive abilities change over hundreds of thousands to millions of years? Can we predict competitive outcomes using phenotypic traits? How much do traits that confer competitive advantage and competitive outcomes change? Here we show, using communities of encrusting marine bryozoans spanning more than 2 million years,...

Data from: The oldest erect cheilostome bryozoan: Jablonskipora gen. nov. from the upper Albian of south-west England

Silviu O. Martha & Paul D. Taylor
Although dominant at the present day, the bryozoan order Cheilostomata did not appear until the Late Jurassic. For over 55 million years after their first appearance, cheilostomes remained low in diversity and disparity, exclusively encrusting and scant in the fossil record. During the late Albian, however, cheilostomes began an explosive diversification coinciding with the appearance of several key novelties. In this paper, we describe a new monospecific cheilostome genus, Jablonskipora gen. nov. (type species Jablonskipora...
