Could we get a ID so they can be labeled. Thanks! #fossil Jayson Kowinsky replied 1 year, 3 months ago The left tooth is an upper Great White (Charcharodon carcharias) tooth. It has a thin root and irregular serrations. The right one looks like a lower tooth. Its probably a Carcharodon hastalis. Its an extinct type of white shark.
