2.27" Scarce Utaspis Marjumensis - Utah

 
This is an middle Cambrian trilobite from the Marjum Formation, Utaspis marjumensis. While molts are not difficult to find maybe only 1-2% of them have cheeks and many of these are poorly preserved. You can dig for days without finding a complete specimen.

This one is quite large at 2.27" inches long and has nice tight cheeks (rare). It was found on top of a limestone layer so it has more inflation than most specimens which are squished flat. This one was personally collected and prepared from a private lease in the House Range. There is no restoration on the specimen.
