Carnivore feeding behaviour is a valuable line of research of increasing value in taphonomic analyses. An interesting component of these studies lies in the differentiation of carnivore activity based on tooth marks left on bone. Among the methodological approaches available, a major protagonist in recent years has been the incorporation of hybrid geometric morphometric studies with artificially intelligent algorithms, reaching over 95% accuracy in some cases. In spite of this recent success, a number of methodological questions are still to be answered for wide scale application of these techniques into other applied fields of science. One of these questions lies in the possible variability induced by prey size on tooth mark morphologies. Here we compile data regarding these effects, using the Iberian wolf as a relevant case study in both contemporary and prehistoric European and North American ecology. The methodology employed opens new questions regarding carnivore tooth marks that should consider the effects of mastication biomechanics. While in most cases prey size is not a significant conditioning factor, caution is advised for future experimentation when considering small prey where some statistical noise may be present. Nevertheless, future experimentation into other carnivore case studies can be considered a valuable research goal.
