Partial funding for this project came from the Geology Foundation of the Jackson School of Geosciences, UT-Austin. A. Woody, R. Malloy, and E. Hattori of the Nevada State Museum allowed access to the specimens reported here. M. Brown, D. Kaley, and other staff members of the Nevada State Museum were extremely helpful during visits to the Nevada State Museum. C. Bell and J. Mead were instrumental in the development of this research project. K. Claeson and J. Olori assisted with figures. S. Rowland, S. Wallace, R. Jass, anonymous reviewers, and my dissertation committee (C. Bell, T. Rowe, J. Mead, J. Sprinkle, and J. Kappelman) made helpful comments on early drafts.
