Here is an interesting European trilobite specimen. This is a nice double example of Placoparia tournemini from the Ordovician of Portugal. Multiple specimens of this trilobite are extremely unusual. The trilobites on this block are completely natural - no compositing has been done. Both trilobites are quite prone and nicely articulated. The bugs are inflated and preserve fine detail. The arthropods are slightly compressed, laterally, due to the metamorphism of the strata in which they are found. Many times, the trilobites from these layers are terribly distorted - not so with these. The fossils have good color and contrast. They are well positioned on the block of matrix. This is a fine multiple specimen of Placoparia from Portugal.
