This website is based upon work supported by the National Science Foundation under Grant No. 9987499 with James Hanken (Director, Museum of Comparative Zoology, Harvard University), Charles R. Marshall (Curator, Department of Invertebrate Paleontology, Harvard University) , and Stephen J. Gould (Curator, Department of Invertebrate Paleontology, Harvard University) as Principal Investigators and Frederick J. Collier (Curatorial Associate, Department of Invertebrate Paleontology, Harvard University) as Grant Project Coordinator.

Carlton E. Brett (Professor, Department of Geology, University of Cincinnati) for his work editing geology content and for allowing us to use his photographs.

James C. Brower (Professor Emeritus, Department of Earth Sciences, Syracuse University) for writing the Trenton Echinodermata introduction, writing species descriptions for the crinoids and cystoids, and reviewing webpage content.

Kathleen Histon (Paleontologist, Department of Paleontology, Geological Survey of Austria) for identifying Trenton nautiloid specimens.

Anna Holden (Faculty Assistant, Department of Invertebrate Paleontology, Harvard University) for her help scanning slides and editing photos in Adobe


Fred H. C. Hotchkiss for sharing his expertise on fossil Asterozoa and writing species descriptions.

Charles E. Mitchell (Professor and Department Chair, Deparment of Geology, State University of New York at Buffalo) for donating Trenton graptolite specimens to the MCZ, his help with identification and description of graptolites, and reviewing webpage content.

Department of Organismic and Evolutionary Biology staff and administration for their help with various items pertaining to grant project activities.

John Pojeta Jr. (Paleontologist Emeritus, U.S. Geological Survey and Research Associate, U. S. National Museum of Natural History, Smithsonian Institution) for suggesting bivalve references, identifying Trenton bivalve specimens, and reviewing webpage content.

Peter Wagner (Assistant Curator, Fossil Invertebrates, Department of Geology, Field Museum) for identifying Trenton gastropod specimens.

Thomas E. Whiteley for donating a large and diverse collection to the Museum of Comparative Zoology, and for allowing use of his library of photographs. This website would have been much more arduous to complete without Tom’s generous sharing of his knowledge of the Trenton area geology, including acting as field guide.
