• In the course of the investigation fossils were collected from the Lower and Middle Cambrian rocks in the area immediately north of Cadiz, California, and from the Lower Cambrian formations exposed at the west base of the Providence Mountains east of Kelso, about 30 miles north of Cadiz. These collections were studied by Dr. Colin Crickmay, University of Illinois, who has written the report on the paleontology.
