Beautiful Orygmaspis Trilobite With Hitch Hiker

Fresh out of my prep lab. Here is a rarely offered Upper Cambrian trilobite, Orygmaspis contracta. It comes from the McKay Group in Southern British Columbia. This example is 1.1 inches in length, and extremely well preserved and prepared. Most of them don't turn out this nice. There is also a juvenile specimen "riding" on it's right free cheek and a partial head of a third next to it. A really sweet specimen.

This is part of a small selection of trilobites from this location which I was able to obtain in a trade.
