About Us

The Evolving Earth Foundation is a small Private Operating Foundation funded by private donors. As an operating foundation, we conduct our own research. Our focus is on the Tertiary paleobotany of western North America with interests in systematics, paleoecology and biogeography. All of us reside in the geologically active state of Washington.


Our Mission

The Evolving Earth Foundation is dedicated to an increased understanding and awareness of the geologic and biologic processes that shape our earth. To achieve our mission, we will provide resources to enhance education, maintain an information Internet community, and support research in the earth sciences and related fields.



Richard Dillhoff – Chairman
