Ring depressions in cattle horncores as indicators of traction use - a cautionary note

In this short communication we call attention to the discovery of a ring depression (a circumferential constriction) in the horncore of a feral bull. This discovery casts doubt on the attribution of similar lesions in archaeological deposits as conclusive evidence of 'cord impressions' resulting from yoking or reining cattle for traction. Drawing upon evidence of horncore depressions in other species, we suggest that they reflect metabolic problems following horn development; additional research is required to test this hypothesis.
