INVESTIGATING THE ORIGINS OF ARCHAEOLOGICAL PRONGHORN BONEBEDS IN SOUTHWEST WYOMING JackN. Fenner It is often unclear whether an archaeological animal bonebed was formed by a mass kill of individuals from a single prey population or through the accumulation of a number of separate kills which occurred over a long time period or at multi ple locations. The isotope ratio variation within animals from an archaeological bonebed can be used to investigate this question by comparing the isotope ratio variation within an archaeological assemblage to the variation within modern pop ulations. If the archaeological variation exceeds that expected within a single population, then an accumulation is indi cated. Otherwise, a single mass kill or a series of kills from a single population over a fairly short timeperiod ismore likely. This technique is demonstrated using carbon, oxygen, and strontium isotope ratios to characterize the amount of variation within pronghorn tooth enamel from six archaeological sites in southwestern Wyoming. The results indicate that theAustin Wash and Trappers Point sites are the result of an accumulation of pronghorn from multiple populations, while the Fire hole Basin, Gailiun, and Boars Tusk sites do not show evidence of accumulation and therefore may be the result of mass kills. The Eden-Farson site formation characteristics are currently indeterminate. A menudo es dificil determinar si un dep?sito arqueol?gico de restos ?seos de animal seform? a traves de la muerte en masa de individuos de una ?nica poblaci?n de presas, o a traves de la acumulaci?n de un n?mero de muertes por separado que tuvieron lugar durante un periodo de tiempo prolongado o en multiples lugares. Es posible utilizar la variaci?n de relaciones isot?picas en los animales de un dep?sito arqueol?gico de huesos para investigar dicha cuesti?n. La variaci?n de relaciones isot?picas de un contexto arqueol?gico es comparada con la variaci?n en de poblaci?n moderna y, si la variaci?n arque ol?gica supera aquella que se espera dentro de una ?nica poblaci?n, se indica una acumulaci?n. De otra manera, es mas prob able una ?nica muerte en masa o una serie de muertes de una ?nica poblaci?n a lo largo de un periodo de tiempo relativamente corto. Dicha tecnica queda demostrada mediante el uso de relaciones isot?picas de carbono, oxigeno y estroncio para car acterizar la magnitud de la variaci?n en el esmalte de dientes de antttopes americanos proveniente de seis yacimientos arque ol?gicos del sudoeste de Wyoming. Los resultados indican que los yacimientos de Austin Wash y Trappers Point son el resultado de una acumulaci?n de antilocapras americanas de diversas poblaciones, mientras que los yacimientos de Firehole Basin, Gailiun y Boars Tusk no presentan evidencia de acumulaci?n y por lo tanto pueden ser el resultado de muertes en masa ?ni cas. Las caracteristicas de la formacion del yacimiento de Eden-Farson a?n no han sido determinadas.
