An ultra rare, Top Quality EXTRA LARGE Edestus heinrichi shark whorl section with 4 big crowns, from Sparta, Illinois. An August Fossil of the Month. This is a Paleozoic shark that lived in swamps that our now underground coal deposits. Excellent preservation and serrations.

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. Four crown whorl sections are extremely rare!
