Discover a gateway to world-class research and education

The Paleontology Repository is a public research facility developed to support and fulfill the mission of teaching, research and service of the Department of Earth and Environmental Sciences and the University of Iowa. This is an international research resource that houses type specimens and makes them accessible to the scientific community as proscribed by the International Code of Zoological Nomenclature. The collection is the property of the State of Iowa, held in trust for the public.

Explore ancient wonders

Gather research insights

Uncover hidden treasures

Every discovery tells a story.

At the heart of paleontology lies the quest to uncover the past. It's about piecing together fossilized evidence, analyzing ancient life, and understanding how the world and its creatures evolved over time.

By exploring these remnants, we gain insight into not just what existed, but why those life forms thrived and ultimately changed the course of history.
