This broad tooth mako (or broad tooth white shark) is near the max size for its species. It is a massive tooth, that at first glance when found, made me think it was a meg. But just for a moment. Most C. hastalis found are 2" or less. Whether you call this Carcharodon or Cosmopolitodus it is a desirable tooth and is currently thought to be the ancestor of the Great White Shark; Carcharodon carcharias.
