This is an exceptionally large and well preserved specimen. At 2" in length this is about as big as this species gets. The preparation uses a technique I've seen a few times before. The trilobite is in a deep well in the rock (about 1.6 cm) and has no crack repair, so how was it found? The answer is that this trilobite was found by splitting a rock. With luck you'd find a trilobite on one half of the split, in dorsal position. Instead the trilobite was on one half of the split rock, but in ventral position (upside down). So the preparator glued the other half of the split rock onto the ventral side and then prepared the trilobite from the other side, in dorsal position.
