Helicoprion has appeared in a number of documentaries and has been mentioned in a number of shows that do not really concern the intriguing shark. This short clip from Animal Planet's River Monsters is the best clip available online from any of the documentary mentions of Helicoprion. It is also the only clip online other than the Discovery Canada clip shared yesterday. As a bonus, one can see a photo of a 3D printed tooth whorl on the River Monsters website for the episode Prehistoric Terror here.
