From the Two Medicine Formation of Montana, USA, this is a VERY RARE fossil tooth of a Troodon formosus, a dromaeosaur-like theropod that is known only from its teeth and still have not been definitively classified by scientists due to lack of more substantial fossil remains. Nevertheless, the teeth are very unique in their pronounced serration denticles, often found in micro-sites. Fossil dinosaur teeth of this creature are not common on the market and this is a very rare chance to add a superb example to a collection. The name Troodon is derived from Greek to mean "wounding tooth". The large serrations most certainly would have been ideal for tearing fleshing and wounding its prey.
This tooth is a CHOICE grade specimen with excellent overall preservation. It possesses very dramatic serrations for which these teeth are known for. The shows only minor natural feeding wear. The enamel is a beautiful rich brown with CHOICE lustrous enamel preservation.
