A model of digestive tooth corrosion in lizards: experimental tests and taphonomic implications

Abstract Corrosion patterns induced by gastric fluids on the skeleton of prey animals may depend on the nature of the corrosive agents (acid, enzymes) as well as on the composition of the hard parts and the soft tissues that surround them. We propose a framework for predicting and interpreting corro...
