Richardson Unnamed / "Priday Black Bed"

This egg is a confusing and controversial one in many ways. I am told it comes from an area just south of and from a layer just under the Red Bed that has never been named or dug very much. Some people have used the name "Priday Black Bed" or "Black Bart" in association with this, but it is important to remember that this is not an official name. Discussion has not raised any alternative to that though. Basically, this is from one of the literally hundreds of pockets of eggs on the Richardson Ranch that have never really been catalogued. The name may have arisen due to the distinctly dark grey exterior of the eggs. In my specimen at least, it is a little darker than the Bed #1, for example.
