A very rare, Top Quality Edestus heinrichi shark tooth with three crowns, from Herrin, Illinois. This is a Paleozoic shark that lived in swamp that our now underground coal deposits. Excellent preservation, serrations, and serration detail. Note - this tooth is on it's original Anna Shale Fm. matrix. 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. No repair or restoration. Authenticity guaranteed.
