An ultra rare, Top Quality Edestus heinrichi, a complete whorl with three crowns from Herrin, Illinois. A July Fossil of the Month. This is a Paleozoic shark that lived in swamp that our now underground coal deposits. Exceptional preservation, serrations, and serration detail. The Edestus shark would have an upper and lower tooth whorl that are vertically opposed. Research showed that they could use their opposing teeth in a scissor-like motion to cut prey. It is the first animal to cut vertically with linear tooth whorls. A very strange looking and unique acting shark. This whorl is incredibly massive at 6" long with three crowns. The whorl body is well perserved with an excellent bright line of pyrite below the crown enamel. The crowns are large at 1-5/8" wide and look fantastic. Note - One crown tip has a small professional repair (~1/8") which is very common for a whorl. Pennsylvanian age from Illinois. Authenticity guaranteed. The Edestus shark recreation image is credited to Julio Lacerdo. These Edestus whorls are extremely rare. This whorl comes with a custon steel stand and  makes a fantastic display piece. My lowest price ever for a complete whorl! 

I01        SIZE:  6" whorl  (1-5/8"+ crowns)  ;  Height is 4-1/8" on stand.
