Sharkray Cross Breed?

I was walking along the beach this morning doing photos for an assignment and nearly stood on this freakish thing. I thought it was a sting ray at first sight but a shark like tail continued from its head down. Im pretty sure its some sort of shark or bottom feeder by looking at it, but if anyone no what it is i would like to no as it was just up from Nobbys beach. Be still freaky if you saw it while you where out surfing or whatever.

thanks to gidd, its a shovel nose shark.
