    Estimating bite force in extinct dinosaurs using phylogenetically predicted physiological cross-sectional areas of jaw adductor muscles by Manabu Sakamoto

    Published 2022-07-01
    “…I present a Bayesian phylogenetic predictive modelling (PPM) framework that allows the prediction of muscle parameters (physiological cross-sectional area, APhys) in extinct archosaurs from skull width (WSk) and phylogeny. This approach is robust to phylogenetic uncertainty and highly versatile given its ability to base predictions on simple, readily available predictor variables. …”

    Peculiar macrophagous adaptations in a new Cretaceous pliosaurid by Valentin Fischer, Maxim S. Arkhangelsky, Ilya M. Stenshin, Gleb N. Uspensky, Nikolay G. Zverkov, Roger B. J. Benson

    Published 2015-01-01
    “…Maximum-likelihood ancestral state reconstruction suggests early brachauchenines retained trihedral teeth from their ancestors, but modified this feature in a unique way, convergent with macrophagous archosaurs or sphenacodontoids. Our findings indicate that Early Cretaceous marine reptile teeth with serrated carinae cannot be unequivocally assigned to metriorhynchoid crocodylomorphs. …”
