A very rare, LARGE, Top Quality Edestus heinrichi shark tooth, from Herrin, Illinois. This is a Paleozoic shark that lived in swamps that our now underground coal deposits. Note - this tooth has a lot of pyrite and the tip is naturally rounded (polished)  which thought to be due to the vertical whipping motion used to slice prey.  Excellent 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 or a vertical whipping 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.
