Archaeofauna • Animal bones turn up in two major archaeological contexts: – At a kill or butchering site, bones may lie more or less the way they were when the hunters left, affected by carnivore scavenging, weathering, and other natural factors. – In camps and villages, we find bones where hunted animals were brought back or domesticated animals were butchered. Identifying Bones 1. Assign each specimen to an element (the anatomical part of the body). Is this bone a rib splinter, part of the pelvis, etc.) 2. Identify the specimens to taxon (kind of animal). Bison Skeleton Showing Major Elements Identifying Bones • number of identified specimens (NISP) The raw number of identified bones (specimens) per species; a largely outmoded way of comparing archaeological bone frequencies. • minimum number of individuals (MNI) The smallest number of individuals necessary to account for all identified bones.

Palynology • The analysis of ancient plant pollen and spores. • Long been useful to the study of prehistoric ecological adaptations by helping to reconstruct past environments. Palynology • Different plants produce pollen that look very different under a microscope. • The individual grains can be identified and tabulated until the analyst records a statistically significant number, say about 400 to 500 grains per slide. • The palynologist converts the counts to percentages and creates a pollen diagram that shows the shift in pollen frequencies between stratigraphic levels within a site.

Symbolic Meaning of Plants: The Upper Mantaro Valley Project • The Inka burned quishuar, the wood that appeared during Wanka III times, in large quantities at festivals and ritually burned human figures carved of quishuar as sacrifices to the divine ancestor of the Inka dynasty. • Trees were symbolically associated with water, as well as with women, clouds, winter, and the moon. • Wood had symbolic as well as economic roles, being used to cement social relations (it was important and rare).
