1.04" Upper Cambrian Orygmaspis Trilobite - BC

Here is an unusual and rarely offered Upper Cambrian trilobite, Orygmaspis contracta. It comes from the McKay Group in Southern British Columbia. This example is 1.04" inches in length.

Finding specimens of Orygmaspis with both cheeks and this nicely articulated is tough. It was painstakingly prepared using air abrasives under microscope, a task that was made extremely difficult due to it's tissue paper thin shell. Access to the collecting localities where these are found is fairly limited.
