Description: A well-inflated example of a dramatic member of the Harpetida, this is Scotoharpes spasskii. The creamy Calcite exoskeleton is complemented by the white limestone matrix. The Harpetida is the newest Order of trilobites, only recently having been erected. This one displays the fine pitted cephalic ring (the cephalon itself is 35 by 32 mm) diagnostic of many members. The trilobite has been prepared with the edges of the winglike genals nearly free of matrix, with only a small amount of matrix left as a protective shield.

This trilobite is exceedling rare, with about one per year complete specimens discovered; usually, only the cephalon is found. Few members of this taxon are ever offered, and even less seen in such a dramatic pose.
