Age and season of pig slaughter at Late Neolithic Durrington Walls (Wiltshire, UK) as detected through a new system for recording tooth wear

The recording of tooth wear is essential for the investigation of age in zooarchaeological assemblages, but most tooth wear methodologies apply only to mandibular teeth, thereby neglecting potentially valuable maxillary data. The large sample of pig maxillary jaws and teeth recovered at Durrington Walls has provided the opportunity to design a new recording method for maxillary as well as mandibular jaws. Work on previously excavated animal bone material from Durrington Walls (Albarella and Payne, 2005) suggested the possibility of seasonal pig killing at the site, but the issue has not, until now, been explored in detail. This paper therefore has a dual purpose: to describe the new method for recording tooth wear on pig teeth; and to use the new information from both the mandibular and maxillary teeth to explore pig age at death and seasonality at Durrington Walls. The results provide evidence of differential deposition of pigs of different ages at Durrington Walls, with one midden context containing younger pigs brought to the site to provide meat for predominately winter-based feasting events, and other contexts containing remains of older pigs (mainly in their second year) deposited in both domestic and more public locales also predominantly in winter. The study highlights the usefulness of maxillary teeth for our understanding of past systems of pig exploitation as well as the desirability of recording their wear in animal bone assemblages.
