I am an amateur astronomer and archeologist.
While surfing through public access to the Mars rovers I came across what looks to be petrified remains.

These are unseen photos until I took the screen shots. I would love to get your expert eye on these photos.

Please take a look at what is attached and tell me if I am just looking at a bunch of rocks.

Yeah, just rocks... rocks and shadows... nothing more.
