(T. Kammer). University of West Georgia students G. Kinison, T. Fanning, and E. Young assisted in coding crinoid specimens and were funded by the UWG Student Research Assistance Program (SRAP). The AEToL character suite was constructed with W. Ausich and improved by helpful input from and discussions with T. Kammer and S. Donovan. We thank the following for providing access to curated specimens: T. Adrian, University of Iowa; R. Burkhalter, Sam Nobel Oklahoma Museum of National History; S. Butts and J. Utrup, Yale Peabody Museum of Natural History; J. Cundiff, Harvard University Museum of Comparative Zoology; K. Hollis, U.S. National Museum of Natural History; B. Hunda, Cincinnati Museum Center. The ideas in this study were greatly improved by discussions with W. Ausich, C. Brett, and M. Hopkins. Constructive reviews by M. Foote, P. Wagner, and D. Wright greatly improved this study.
