This is an exceptionally preserved undetermined Tyrannosaurid (NANOTYRANNUS) tooth “spitter”. The tooth is well worn at the tip indicating it was in his mouth for a long time and worn down over time before being broken off.

As Theropods eat, they break off the teeth as new ones are erupting through the jaw. The teeth are constantly growing. These small broken teeth without the roots are called “spitters”. They are broken from a live dinosaur. When a creature dies the teeth fall out with the roots, they are called “rooted teeth”. The break on this tooth is clearly visible, shows great detail and the tooth is a wonderful brown color. The worn tip of the tooth is exceptional indicating it was in the mouth for a long time before being broken.

This is a small Tyrannosaurid tooth from probably the Nanotyrannus. Measuring .37 inches in length with good enamel preservation. The serrations are in fine shape with slight wear to the tip of the tooth from feeding.

Teeth such as these are usually collected from ANT HILLS. The ant hills in these areas are very large, the paleontologists scoop the dirt and pebbles into sifting screens and sift to find the teeth, small mammal bones and other small fossils. The ants are really good paleontologists removing items in their way as they dig.
