Dear Emily, I strongly believe that intrusive bones should be excluded from the main table, though, if there is any possibility that they have a cultural origin, they can be shown separately. And, of course, they should be omitted from calculations. I have said so in print! Good to eat and good to think with: classifying animals from complex sites. In Animal Bones, Human Societies. ed. P. Rowley-Conwy (2000).Oxford, Oxbow: 179-189.

Both versions appear in published zooarch reports. The second question is what to do with bones of intrusive species in NISP tables? In Britain and Ireland these are typically rabbit bones and again there seems to be different approaches in the literature to including/excluding counts in tables. Thanks in advance.
