Strange shark

I found a video on a strange shark:

Helicoprion is the name of that shark.  At first, I thought it was a fake, you know like a well done photo montage.  There are a lot of people with too much free time on their hand.  In this case, it is true and nature have a true twisted sense of humor.  Too bad this shark is a prehistorical creature.  If he would exist today, it would make an huge sensation with every handyman person.  I may be messed up but now, I can't stop thinking of "Handy" by Weird Al Yankovic (https://www.youtube.com/watch?v=eXiwYUCe_bY)   I would see the helicoprion well as Weird Al tablesaw!  It wouldn't be the first time having a gore scene in his video like in "You don't love me anymore" (https://www.youtube.com/watch?v=kWD5gdpt4Dw)

I wonder if the shark was successful in it's time.  Of course, he is no longer around, so the long term survival is not to be talk about.  I wonder what he could eat.  With his denture and jaw, I guess he could not eat big prey.  I don't find him that big but it is a photo, so I am not the perfect judge in that matter.  At least, this shark have a winning look.  Too bad he won't be talk about (at least mentionned) on Shark week, on the Discovery channel (http://www.discovery.com/tv-shows/shark-week/)
