Naturally-occurring tooth wear, tooth fracture, and cranial injuries in large carnivores from Zambia. [PDF]
PeerJ, 2021 Determining the incidence and causes of craniodental damage in wild carnivores is often constrained by limited access to specimens with associated ecological data, such as prey type and abundance. We assessed dental condition and cranial injuries in lion,

Tooth fracture frequency in gray wolves reflects prey availability [PDF]
eLife, 2019 Exceptionally high rates of tooth fracture in large Pleistocene carnivorans imply intensified interspecific competition, given that tooth fracture rises with increased bone consumption, a behavior that likely occurs when prey are difficult to acquire. To
