Out of stock

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.

The Edestus heinrichi or Edestus minor, the Coal shark or scissor shark tooth, are two rare Pennsylvanian age sharks found in an underground coal mines in Illinois. Edestus heinrichi tooth exhibits a unique broad symmetrical triangular crown with huge serrations. Whereas, the Edestus minor tooth exhibits a more narrow asymmetrical 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" which are placed vertically at the center line of the upper and lower jaws. A whorl could include 5-10 or more crowns. A very strange arrangement of teeth which would be used to slice prey. These teeth are well preserved. These teeth are from the Anna Shale Fm. (Carbondale Group) - approx. 300 million years in age. It is always difficult locating these rare teeth. No repair or restoration to any of these teeth!
