Nocturnal dinosaurs, again: the strength of discriminant analysis in quantitative paleobiology
More on nocturnal dinosaurs, or, importantly, on our quantitative approach to infer ecology and behavior in fossil vertebrates. Hall et al.’s technical comment provided us with the opportunity to further explain the strength of our approach. Schmitz, L. & R. … Continue reading
