This is an absolutely incredible collector quality auriculatus shark tooth from the Suwannee River in north Florida. This specimen has impressive size at 2.77". It is a less common lower jaw example. The enamel and root are both naturally highly polished from thousands of years on the river bottom. The enamel coloration ranges from green at the tip all the way to black where the enamel meets the root. Really sexy dagger shaped specimen. Very high quality and showy specimen.
