Volunteers in the Paleontology Department assist with many tasks associated with maintaining the extensive collection. This includes fossil preparation, numbering fossil invertebrates, micropicking for hidden treasures, organizing the collection, and entering records in the Department's database, and checking the collection for pest activity. If you are interested in this or other volunteer opportunities, please complete an  online application . The Director of Volunteers will contact you to schedule an interview or invite you to an orientation.
