This is an extremely plate of Ordovician trilobites. It is a slab with two different species of trilobites on one rock. There are two Ceraurus globulatus and three Calyptaulax calicephalus, which is unusual from this formation. Most of the bugs are nicely outstretched and have great detail. The thick shell exoskeleton is almost totally intact, which is VERY unusual. This a unique fossil with many rare Ordovician trilobites represented.
This fossil was collected and obtained legally, and is also being sold legally.
