Distinguishing agents of bone modification at paleoanthropological sites is at the root of much of the research directed at understanding early hominin exploitation of large animal resources and the effects those subsistence behaviors had on early hominin evolution.

The Virtual Goniometer: A new method for measuring angles on 3D models of fragmentary bone and lithics
