A fossilized shark tooth of a broadnose sevengill shark, or Notorynchus cepedianus from the Aurora, Beaufort County, North Carolina, United States. The teeth of these cow sharks can be found in both the Miocene aged Pungo River Formation and the Pliocene aged Yorktown Formation in this area. This species is still alive today and is the only surviving member of its genus. While the number of cusps could lean towards Hexanchus, the coarse serrations on the mesial edge suggest Notorynchus.

hi

Day by day,

Safe behind these windows and these parapets of stone,

Well you only need the light when it's burning low,

I get wings to fly,

Bravely bold Sir Robin.
