Acanthoyge Belenopyge bassei Moroccan Trilobite with Exposed HypostomeDescription: This is a fine fossil of a trilobite from the Middle Devonian El Otfal Formation deposits near Jebel Issoumour this taxon is a member of the Order Lichida, Family Lichidae, and is infrequently available with this preservational level. Typically called Lobopyge, it is actually a member of the genus Acanthopyge and has recently been placed in the subgenus Belenopyge. It is well-positioned on its limestone matrix base, with the genal and pleural spines well-displayed against the light-colored matrix. With this one preserved in a contraflexed pose, the hypostome was readily exposed as seen here. It has a recently-assigned “cousin” in the Devonian deposits of Oklahoma, Acanthopyge consanguinea (Bug X) which can be seen in my offerings from the incomparable preparator Bob Carroll.
