Middle Cambrian Wheeler Shale

Millard County, Utah

Two early echinoderms preserved along the same bedding plane from the middle Cambrian Wheeler Shale, western Millard County, Utah, a number of miles east of the eastern border of White Pine County, Nevada. Both have been assigned to the genus-species Gogia spiralis. Photograph courtesy an anonymous individual. I edited and processed the image through photoshop.
