Description
Helicoprion sharks are a bit mysterious. All that's known of them are their fossilized tooth whorls and a few other fragments of teeth. No one is entirely sure how the whorl would have been oriented in their mouths, or how it was used when they fed.

So all I included in here are the elements of the shark that are known, even if they are not placed correctly in an anatomical sense because that hasn't really been established just yet.

Colored pencil and ink on cardstock. 1 x 1" in size.
