The far shots of the skeleton look like they've been put in with an advanced editting program of some sort. Also, I can't find anything about it on sites like CNN and National Geographic.

It could be the Bloop (some sort of giant creature supposedly living at the ocean's deepest depth) or something, though.

EDIT: Looking around, there's a lot of stuff about giant this and giant that being discovered. There's bones of some biblical giant, the giant squid (the only one I've found on a respected news site), and some giant creature in the water of the Phillippines.
