Just out @ Palaeontology A new phylogeny of Stegosauria (Dinosauria, Ornithischia) Author(s) Thomas J. Raven, Susannah C. R. Maidment Abstract: The stegosaurs are some of the most easily recognizable dinosaurs, but are surprisingly rare as fossils. Consequently much remains unknown about their palaeobiology, and every new stegosaurian find contributes to our understanding of the evolution of the clade. Since the last attempt to examine the evolutionary relationships of Stegosauria, new

Just out @ PeerJ Title:  Specimen-level phylogenetics in paleontology using the Fossilized Birth-Death model with sampled ancestors Author(s): Andrea Cau Abstract: Bayesian phylogenetic methods integrating simultaneously morphological and stratigraphic information have been applied increasingly among paleontologists. Most of these studies have used Bayesian methods as an alternative to the widely-used parsimony analysis, to infer macroevolutionary patterns and relationships among species-level or higher taxa. Among recently introduced Bayesian methodologies, the Fossilized Birth-Death
