This is fun, its a billion pixel photo from Mars and its got a lot of detail. The screenshots above show an alien skull. I have seen other skulls similar to this one, sorry, I lost count, but a lot. So I recognized it right away for what it is.
Also there was a screaming face (below) with a larger face not far from it. Neither is human but the smaller does have some resemblance to old Mayan carvings.
Below is a crude sculpted head sitting upright. Its easy to make out its mouth, chin, eyes, forehead.Below we see a sculpted object thats hard to make out, but it is clearly made by intelligent beings.
