Abstract

Korsi Dora Vertebrate Locality 1 (KSD-VP-1), located in the Woranso-Mille paleontological study area in Ethiopia, records one of the least-sampled temporal periods of Australopithecus and is one of the few to sample the earlier period of the known time range of Au. afarensis. It has yielded one of the most complete skeletons of Au. afarensis known thus far. In this paper, the taphonomy and paleoenvironment of KSD-VP-1 are explored through the collected faunal specimens. In addition to descriptive accounts of the surface modifications on the bones, data on several taphonomic factors were also collected and analyzed, the results of which suggest that the KSD-VP-1 faunal assemblage is autochthonous and that there was minimal transport and disturbance of bones. The focus of the paleoenvironmental analysis is the use of the presence and relative abundances of indicator taxa along with other lines of evidence, such as ruminant dietary adaptation and geology. The combined evidence suggests that the paleohabitat at KSD-VP-1 was likely medium to dense woodland with some open areas of grassland or shrubland distal to the locality.

Acknowledgments

I am grateful to Y. Haile-Selassie for inviting me to study the taphonomy and paleoecology of KSD-VP-1 and to the members of the Woranso-Mille Paleontological project who collected the fossil material analyzed in this study. I thank the Authority for Research and Conservation of Cultural Heritage and the National Museum of Ethiopia of the Ministry of Culture and Tourism for permission to study the fossil material under their care. The Afar Regional Government, its local administrative units, and the Afar people of the Mille District are thanked for facilitating and participating in the fieldwork that resulted in the recovery of the material discussed here. Thanks to S. Curran, K. Reed, and an anonymous reviewer for helpful comments. Field research was supported by Grants BCS-0234320, BCS-0542037, and BCS-0321893 from the National Science Foundation and by the Leakey Foundation, the Wenner-Gren Foundation, and the National Geographic Society. Laboratory research for this study was supported by the Leakey Foundation.
