Edestus - Scissor Tooth Shark

The Edestus heinrichi or Edestus minor, the Coal shark or scissor tooth shark, are two of the very rare Pennsylvanian age shark species found in an underground coal mines in Illinois. Each tooth exhibits a unique broad triangular crown with large serrations. The roots are also quite unique as they appear as long arms with the crown at the end. The roots would stack and interlock to form a "tooth whorl" as per the photo above. 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. Authenticity guaranteed.
