.8" Aulacopleura (Paraaulacopleura) Trilobite - Rare

This is the first example of this small, proetid trilobite which I've had, and it's far nicer than the few others I've seen. All the references to it I can find have labeled as Aulacopleura, though that genus is more known as being silurian in age. This specimen is nicely prepared, though the left cheek is slightly pushed under the trilobite.
