Large Elrathia marjumi Trilobite in field of disarticulated Gogia plates OUT OF STOCK

Uncommon Elrathia marjumi, measuring 3.6cm, nestled in a field of disarticulated plates from Gogia eocrinoids.  E. marjumi is the uncommon cousin to the more prolific Elrathia kingii, with a small spine bulging from each side of the first segment of the pygidium defining the species. They are also typically larger than other Elrathia species.  This specimen has a cranidia of another trilobite just above it, forming sort of a “high hat” aesthetic.  Excellent specimen!
