Strat unit: Silica formation

Submitter notes: This believed to be the lateral plate of the third species of Phyllocarid from the Silica and shows a bit of the lateral ridge that is not present in other species of Phyllocarid from this formation. Due to the fragmented nature of the specimen however, this could also be part of one of the other species found in the Silica.
