Abstract
While working with live specimens in the field, processing subjects with the least amount of stress or disruption possible is ideal. Field measurements are the basis of live-specimen field ecology. Alternatively, in zooarchaeology measurements of bone, skeletal and cranial features are done best without obstruction from living or non-living tissue, debris, or other objects embedded in or attached to bone because it complicates measuring techniques. This operating procedure marries zooarchaeological and field ecology morphometric approaches to enrich ecology and natural history-derived morphometric data sets for small mammals. We offer a harmless, quick, and close to accurate cranial measurement protocol that can be taken during natural history or ecological field collection activities. For ease of comparison across age, sex, species, and environment the three measurements proposed in this procedure are interparietal bone width (IPBW), palatal breadth (PB), and tooth row length (TRL). Combined, they provide a rough estimate of cranial size utilizing a geometric morphometric landmark approach.
