Here is an excellent example of an unusual trilobite. This is a Subasaphus platyurus from the Ordovician of Russia. It is easy to see the differences between this type and the more common Russian Asaphids - this type has long genal spines, for example. This trilobite is extremely 3-dimensional and wonderfully articulated. The bug is quite prone and exhibits very fine detail. The sweeping genal spines are beautifully displayed, and the large eyes are easily seen. The thick-shelled exoskeleton has great natural color - it is a dark caramel with natural highlights. The trilobite is well showcased on the LARGE, buff-colored block of sculpted limestone. This is a very displayable specimen of a highly collectible trilobite.
