Zilchovaspis Moroccan TrilobiteDescription: A elegant example of a member of the Order Phacopida, Family Dalmanitidae with many fine details present. While most frequently known in the trade as “Odontochile”, this one is actually Zilchovaspis. The most diagnostic features of this taxon are the parabolic cephalon and pygidial spine. Odontochile has a more circular cephalic outline, and a shorter, broadly-based pygidial spine. Both genera bear a strong resemblance to the contemporary genus Huntonia from the Devonian of Oklahoma. This one is on the high end of the size spectrum, well over half again as large as most more typically seen examples.
