Utaspis Marjumensis Trilobite - Negative

This is the negative impression of a fairly scarce trilobite from the Marjum Formation, Utaspis marjumensis. It's common to dig the site where these come from for days without finding a complete one with cheeks. This negative impression was found in the talus pile, and I spent an hour looking for the positive but it was long gone.
