ACKNOWLEDGEMENTS I am grateful to P. Gingerich, G. Gunnell, and J. Bloch for the opportunity to lead the study and description of UM 87990. P. Gingerich and W. Sanders facilitated and oversaw the production and provision of high quality casts of this specimen. A. Walker and T. Ryan provided HRxCT scans of this specimen and others at the Center for Quantitative Imaging, Pennsylvania State University. S. Judex and C. Rubin provided HRxCT scans at the Center for Biotechnology of the Department of Biomedical Engineering at Stony Brook University. M. Godinot, P. Tassy and C. Sagne of MNHN, and M. Pellouin provided access to important comparative specimens of Plesiadapis tricuspidens and Platychoerops. This research was enhanced by discussions with J. Bloch, P. Gingerich, M. Godinot, J. Perry, M. Silcox, R. Secord and many other researchers. D. Krause, M. O’Leary, J. Fleagle, W. Jungers, and P. Gingerich read and enhanced previous manuscripts. It was made possible by funding from a National Science Foundation grant to P. Gingerich and G. Gunnell (BCS-0129601), a National Science Foundation grant to D. Krause and J. Bloch (EAR-0308902), and a National Science Foundation Graduate Research Fellowship, an Evolving Earth Foundation grant, a National Science Foundation Doctoral Dissertation Improvement Grant (BCS- 0622544), and an American Society of Mammalogists grant to D. Boyer. 210
