Food shortages can leave diagnostic, and in the case of the dentition, irreversible changes in mineralized tissue that persist into historical and fossil records. Consequently, developmental defects of tooth enamel might be used to track ungulate pop

Although tooth fracture may have severe energetic and behavioural implications for carnivores, it occurs commonly, perhaps as a result of a high risk diet and lifestyle. To investigate the influence of intraguild competition and resource availability

The shape of the cranium varies widely among members of the order Carnivora, but the factors that drive the evolution of differences in shape remain unclear. Selection for increased bite force, bite speed or skull strength may all affect cranial morp

Sexual dimorphism in craniodental features is investigated in a sample of 45 carnivore species in relation to allometry, phylogeny, and behavioural ecology. Dimorphism is more pronounced in both upper and lower canine size and strength than in carnas

Although the great size and procumbency of the incisor teeth of many saber-toothed carnivorans have long been recognized, the potential functional significance of carnivoran incisor size and shape remains largely unexplored. Here, we explore upper in

Extinction of the woolly mammoth in Beringia has long been subject to research and speculation. Here we use a new geo-referenced database of radiocarbon-dated evidence to show that mammoths were abundant in the open-habitat of Marine Isotope Stage 3
