SCARCE Asaphus expansus Trilobite from Norway

Description: A well-inflated example of a scarce Asaphid, this is Asaphus expansus,. The name is derived from its relatively broad thorax. It appeared early in the evolution of the Asaphidae, giving rise to the line of some 30 different Asaphids. This one is quite 3-D in appearance and nearly prone. The rich ebony color is a stark contrast to the café au lait coloration for those from Russia which are far more often seen. Interestingly enough, all the trilobites from this region display this same rich color, making for a dramatic display.
