Greenops Devonian Trilobite from New York

Description: Elegant example of a member of the Order Phacopida, Subfamily Asteropyginae with dramatic genal and pygidial spines. The Asteropyginae have recently undergone extensive revision, with several members of the genus now placed in the recently-erected genera Bellacartwrightia and Kennacryphaeus. Most are usually found as disarticulated specimens, but this one is quite complete, with fine eye facets and pustules on all parts of the exoskeleton. This is an exceptional prone and highly 3-D example of the type, well-positioned on its matrix base.
