The age of the find is remarkable, but what makes this even more rare is the fact that the entire skeleton appears to be more or less intact: head, vertebrae, flippers, and all.
As Discovery News notes, "Our genus, Homo, wasn't even around 3 million years ago, so this wasn't some sort of super prehistoric zoo. The site then, during the Pliocene, was under water."
Construction at the site will continue.
