The research described here was funded by research grants from the National Science Foundation, the Wenner-Gren Foundation for Anthropological Research and a J.S. Guggenheim Foundation Fellowship. Among colleagues who made this research possible and fruitful were C. Leroy-Prost, M. Perpère, H. de Lumley, D. Vialou, H. Delporte, J.-P. Mohen, R. Castanet, A. Roussot, M. Oliva, J. Hahn, M.Otte, D. Cahen, E. Way, L. Breitborde, J. Ketcham, G. Cole, M.-H. Marino, D. Buisson, O. Soffer and A. Rodriguez. I especially wish to thank my Russian colleagues N. Praslov, N. Bader, L. Mikhailova and A. Senitsin for their warm reception and generous assistance.
Experiments were conducted at NYU under my supervision, and with the participation of Magen O'Farrell, Anibal Rodriguez and Joanne McLean (in the early stages). Their help and observations are greatly appreciated. Jacques Pelegrin generously fabricated and provided to us a quantity of early Aurignacian tools that were essential to this research. Replicative experiments would have been impossible without generous gifts of raw ivory from the US Fish and Wilflife Service (Special Investigator Sam LiBrandi) and the Paleontology Department of the American Museum of Natural History. Heidi Knecht aided me in the SEM analysis and photography of Aurignacian beads.
