Feeding the scavengers. Actualistic taphonomy in the Jordan Valley, Israel

This paper describes the results of a 3‐year project carried out in the Jordan Valley, Israel, in which the influence of specific local environmental conditions, such as scavenging, weathering and scattering of carcasses, were related to the rate of their bone survival. During the 3 year period, the taphonomy of 16 whole animal carcasses, deposited in a nature reserve and agricultural cultivated area were compared. The exact age, date of death and weight of all animals was known. Results of animal scavenging activities on the carcasses, such as disappearance of bones and damage, such as tooth marks, breakage, gnawing to the leftover bones, were recorded at the end of the initial, intensive scavenging period (Phase I), and at later dates. Bone scattering maps were drawn at the end of Phase I and 2.5 and 3 years later. Weathering of surviving bones at the sites is described. Results show that in the Jordan Valley Nature Reserve, scavenging is the most important taphonomic agent causing total disappearance of all bones of young dairy calves, and reducing amount of bones remaining of more mature animals to a minimum. These small number of leftover bones, after only 2–3 years are the only candidates for eventual burial and fossilization. The loss of most of the bones through scavenging in the nature reserve might cause serious bias to conclusions about subsistence behaviour of prehistoric man. This is a taphonomic actualistic analogue to eventual conditions in prehistoric times. Copyright © 2000 John Wiley & Sons, Ltd.
