1.45" Upper Cambrian Orygmaspis Trilobite - British Columbia
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 1.45" long which is good sized for the species in a well preserved.
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. This specimen is one of a small number I received in some trades with the claim holder.
