This is a very large US trilobite. It is a massive Trimerus delphinocephalus from Middleport, New York. This is one of the rarer types of trilobites from the Rochester Shale. This specimen is complete and is well over six inches long- very few types of trilobites found in the United States are this large. The specimen has nice coloration and very good detail. The thick shell exoskeleton is well-preserved. The bug is beautifully centered on the large, squared block, not on the edge of the plate like most. The fossil is also very inflated and 3-D for this type. This is a huge, displayable example of this uncommon species of trilobite.
