This is a nice multiple plate of Jujuyaspis keideli from the Ordovician of Argentina. There are at least 4 positive trilobites on this slab that are essentially complete. There are also many partials and several negatives. The trilobites are naturally positioned all over the surface of the rock. There are also many partials on the back side of the plate! This is an unusual multiple specimen of Jujuyaspis from Argentina.
Note: Argentina has now banned the export of all fossils. We will strictly abide by and enforce this law - we will not acquire new fossils from Argentina. However, this fossil was collected and exported prior to this law, and can be sold legally.
