Master List of UI Paleontology Repository Collectors

The UI Paleontology Repository holds over one million specimens, and the initial phase of the project included only the following collections: Trilobites, Pleistocene Mammals, Fish, and Echinoderms.

We continue to survey collections and add collector biographies with the help of UI student interns from the SEES and the Museum Studies Certificate Program. Thank you to all our contributors!
