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.

A HUGE, TOP QUALITY Spinosaurus aegyptiacus tooth from the Kem-Kem region of Morocco. An October Fossil of the Month. High quality enamel with well preserved and pronounced grooves running up the crown. Little crown tip wear for a big tooth. A fantastic deep red patina - rare color for a Spino tooth, and the surface has a drusy crystalline appearance - very nice and very rare. Plus this is an extra thick BIG Spino tooth that would have been easily 1-1/2" thick at the base - see photo. One of the fattest Spino teeth that I have seen. No cracks. No repair and restoration. A very special, big collector's tooth from an extra large Spinosaurus - the 50 foot variety! Plus rare deep red color with a crystalline surface. An essentially PERFECT tooth. You do not see the top quality BIG Spino teeth very often. Authenticity guaranteed. Best of the BEST!
