This is a very rare Asaphus trilobite. It is an Asaphus delphinus from Russia. This is the first nice one of these we have seen. It is easy to see the differences between this type and the more common Russian asaphids - especially in the cephalon. The trilobite has great natural color and detail. The bug is beautifully centered on the natural matrix block. This is a very collectible Russian trilobite.
