The Edestus heinrichi or Edestus mirus, the Coal shark, are very rare Pennsylvanian age shark found in an underground coal mine in Sparta, Illinois. The tooth exhibits a uniquebroad triangular crown with huge serrations. The roots are also quite unique as they appear as long arms with the crown at the end. The roots would interlock to form a "tooth whorl." 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. Norepair or restoration to any of these teeth!
