The statue is Taweret, confirmation from ABC.com recap:
"In an unknown room, we see a man dressed in white at a spinning wheel creating a tapestry with an intricate design containing Egyptian and Greek symbols. We cut to the man sitting on the beach cooking fish over a fire. It's morning, and on the horizon, out over the ocean, a large ship is sailing towards the island. Another man, this one dressed in black, walks over to the Man in White. The Man in Black asks why the Man in White brought the ship to the island -- is he still trying to prove the Man in Black wrong? The Man in Black says they come, fight, destroy, corrupt, and it always ends the same. The Man in White tells him it only ends once, and everything else is just... progress. The Man in Black says he wants to kill the Man in White, and one day he's going to find a loophole. The Man in White says he'll be right there. The Man in Black leaves and addresses the Man in White as Jacob. Yes, this is Jacob. The camera pulls back over the ocean, and we see they were sitting on the base of a giant stone foot. And next to the foot is another foot -- and both feet have four toes. And as the camera pulls back, we see what we've been waiting to see since we first glimpsed that four-toed foot over three years ago... the towering, majestic statue of the Egyptian goddess Taweret. And we clearly know we're a long time ago, so let's get the finale of season five started --"
"So, it's not Anubis, it's not Sobek. It's Tawaret. I know it doesn't look exactly like some of the hippo-like images that are out there, but as far the show and the story is concerned, the statue is Tawaret, the Egyptian Goddess of fertility.
