The Lannacus species of asaphid trilobite is a large trilobite from the Anti-Atlas Ordovician deposits in southern Morocco. If you asked us to find the finest example of a Lannacus trilobite, then this specimen would be a candidate. It is of MAXIMUM SIZE and even includes the COMPLETE concretion in which is was found, including the upper negative impression half. This incredible specimen has been completely prepared in our lab in Florida so we can attest to a full and accurate assessment of what work has been done to the specimen. The entire trilobite has been fully exposed with both halves of the large, original concretion included. The negative impression further demonstrates the authenticity and originality of the positive half of the concretion.
Quality examples of this trilobite have now become extremely scarce. The entire trilobite in this example, is fully articulated and exhibits the fullest possible, lifelike inflation along with wonderful detail and preservation. The orange coloring is a result of the naturally-occurring limonite pigment and has been sealed for protection. The eyes are both genuine and exhibit full, pronounced anatomical relief, VERY RARE! The outer surface of the concretion has NOT been colored or painted and has only been sealed to also preserve this beautiful natural coloring as well as to strengthen and stabilize any fractures in the concretion.
A large concretion trilobite that makes a fantastic display fossil for it's rarity, 100% COMPLETE, natural condition and impressive size.
