Apparently the statue is not of Sobek, but of Taweret, the Egyptian Goddess of birth, rebirth and the northern sky. It's been confirmed by both ABC and JJ Abrams:

I still think it looks more like Sobek though.

ah, asano. My girlfriend and i were just having this discussion about which it looks like more. Nice.
