An incredibly prepared, GEM QUALITY Erbenochile erbeni trilobite, the "Big Eyes" trilobite. An April Fossil of the Month. German preparation. A very ornate design with thorax spines and incredible "tower" compound eyes! The massive eyes provided 360 degree visual coverage and allowed this trilobite to see behind itself over the thorax. Excellent shell and spine preservation. Large size. A very rare species! An Early Devonian (410 mya) trilobite from the Jbel Gara el Zguilma area, Atlas Mts., Morocco. Definitely one of my favorites! Authenticity guaranteed.  This is a very special spiny trilobite. Note - specimen weights 1.6 lbs. International orders may require supplemental postage. Please inquire.
