An ultra rare, LARGE Top Quality Edestus heinrichi shark whorl with 7 big crowns, from Herrin, Illinois. An October Fossil of the Month. This is a Paleozoic shark that lived in swamps that our now underground coal deposits. Excellent preservation and serrations. This whorl is incredible teeth detail - the first 5 crowns are all natural and the the last two have some top repair. One of the finest whorls that I have had. 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. A very strange looking and unique acting shark. Shark recreation image is credited to Julio Lacerdo. These rare teeth are Pennsylvanian age from Illinois. Note - Two crown tips were professionally retored. Authenticity guaranteed. Seven plus crown whorl sections are ultra rare!  The BEST.
