Here is a interesting  Utah Trilobite of the genus  Bolaspidella.
Most likely belongs also this specimen to Bolaspidella housensis. However is shows especially on the Cephalon some affinity to Bolaspidella sp. sensu L. Gunther & V. Gunther 1981. But also this specimen has the typical spines on the axial rings nicely.
 The species Bolaspidella housensis seem to have a high variability.
Besides the right eye is missing offers this trilobite a beautiful preservation.
