Zooarchaeology What is Zooarchaeology? Recovery and Counting Comparative Collections Subsistence Strategies Seasonality What is Zooarchaeology? The Study of animal bones from archaeological sites. Studies can focus on subsistence, hunting strategies, environmental change, domestication of animals, and ceremonial use of animals. History of Zooarchaeology 50 years ago archaeologists had bones on their sites and they began asking zoologists to identify them. Some people became more and more interested and involved in these bones and began to specialize in it. Today most zooarchaeologists, such as myself, are trained as archaeologists and specialize in zoology. Have taken a lot of zoology classes. Including Malacolgy, Ichthyology, Avian Osteology, Vertebrate Osteology. Recovery and Counting Recovery of bones is subjected to bias depending on screen size and soil preservation. Counting bones is not like counting flakes, flakes are extremely predictable in how they break, whereas bones are not predictable. Several techniques can be used to count bones: NISP-Number of Identified Specimens, counts each bone fragment as a unit. MNI-Minimum Number of Individuals, first defined by T.E. White in 1953 to account for each animal as an individual unit. need to identify lefts and rights of bones from a given species. For MNI Given an assemblage (group of bones): How many individuals? 3 L proximal humeri (upper arm bones) 2 R proximal humeri 4 R distal femurs (upper leg bones) 2 L distal femurs Meat Utility Indices MNI can be used to calculate how much meat can be obtained from a given animal. 2 deer @ 100 lbs. of meat=200 lbs. 5 rabbits @ 5 lbs. of meat=25 lbs. Comparative Collections Cannot identify animal remans without having some comparative collection. modern skeleton for comparative purposes. must have a series of specimens in a particular species, representing different ages and sexes. Zoologists generally have collections of skulls and animal skins because they are interested in identifying and classifying modern species. Weights and measurements need to be recorded so that utility indices can be estimated. Preparation Maceration-in water Dermestid Beetles Bleach-Biz Simmering-cooking the meat off University of TN has a skeletal collection of over 12,000 specimens one of the best in the country. Subsistence Strategies The primary focus of zooarchaeology is to discover the subsistence techniques used by prehistoric and historic people. It is important to study behavior through animal remains because most of what humans do is involved with eating. celebrations-some foods have higher status than others. nutritional stress-what do people eat and do when times are lean? i.e. increase diet breadth habitat-a lot of what people eat (primarily prehistoric) is predicted and controlled by their environment. Other aspect of diet reflects human behavior: age and sex of animals season of site occupation cultural preferences Strategies Hunting and Gathering-wild animals Pastoralism-herding domestic animals Horticulture-wild and domestic animals Agriculture-wild and domestic animals How is seasonality documented? Presence/Absence Migratory birds Cold-blooded Reptiles/Amphibians Animal young Skeletal Change Antler Growth Tooth Growth Epiphyseal Fusion Incremental Growth Structures-Fish Bones most useful are otoliths and spines otoliths are calcareous “ear stones” in the inner ear associated with balance. Mammalian teeth cementum annuli laid down during the year. dark band slow growth, light band fast growth. Case Study: Oronsay Island, Scotland Wilkinson’s study of coalfish from Mesolithic sites on island (5300-4600 ya) Otoliths-sectioned and season of death documented. Found seasonal fishing at four sites Cnoc Sligeach-July to August Cnoc Coig-Sept-November Priory Midden-Winter to Early Spring Caisteal nan Gillean-Spring to Summer Probably movement of one group from site to site over the course of the year.
