This is a very nice multiple plate of trilobites from the Cambrian of Utah. There is a nice, complete example of Elrathia kingi on the slab. The detailed Elrathia is nicely articulated - the specimen has the free cheeks intact. The black bug is very sharp in appearance and contrasts beautifully with the grey matrix. The trilobites are well showcased on the large, squared plate of shale. And, best of all, this wonderful specimen has a pair of Peronopsis agnostids preserved on the plate! This is a very nice multiple plate of two different trilobites from the Wheeler Formation.
