Evolution and Biogeography of Burgess Shale Type Fossils

Our Purpose

The purpose of this web site is to provide an overview of the diverse Cambrian life that flourished in an ancient sea that covered what is now Utah over 500 million years ago.

Evidence of Utah's Cambrian life is revealed by an exceptionally well-preserved fossil record of soft-bodied life forms that rarely stand any chance of becoming fossils. The focus of this web site is to showcase these special fossils, as well as to describe their geological and evolutionary context.

Many of the fossils shown on this web site were collected by the Gunther Family of Utah, who were instrumental in bringing these fossils to light. University of Kansas Professor Emeritus Richard Robison, along with colleagues, was a pioneer in describing and documenting these amazing fossils.

"Golden outlines of people holding hands around the earth with the white letters NSF over it"The research presented on this web site was supported in part by the National Science Foundation (Grant EAR-0518976 to Bruce Lieberman, University of Kansas). The content of the site was developed by Jonathan Hendricks, who worked with Bruce as a post-doc on that award, and is now Director of Science Communication, Paleontological Research Institution. The site went live in 2008 and in 2022 was updated to this new format.
