In addition to his notable field skills, Will Downs was a fine preparator and often called upon to prepare difficult specimens including the Z143 rhinoceros teeth of this report, which were encased in matrix. Will also found the rhino tooth from Z147. My gratitude to J. Hooker of the Department of Palaeontology, Natural History Museum, London, who graciously provided access and insight to specimens under his care from Bugti Hills. The comments of P.-O. Antoine and L. Flynn were insightful and improved this manuscript. For logistical support of fieldwork at Zinda Pir Dome, my thanks go to the Pakistan Museum of Natural History, Islamabad. This research was supported by National Geographic Grant 6402-99 and a grant from the DePaul University Research Council.
