Spine-On-Spine Ceratarges & Austerops Trilobite Association

This is a WORLD CLASS trilobite association of an impeccably prepared Ceratarges and a large Austerops. The preparation is so good that even secondary spines on the spines of the Ceratarges are preserved, a feature almost always destroyed during preparation. There is no restoration, and matrix looks natural and mostly free of tool marks. You won't see preparation nicer than the work done on this specimen.
