The Anatomical Record, EarlyView.Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

The Anatomical Record, EarlyView.Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated

The Anatomical Record, EarlyView.We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...
