Shadows, contours, light angle. Nothing to see here except another rock. Another example of the human "eye" looking for familiar patterns.

It's not a good image, having been enlarged; from what I see it has some shell-like features, wavy edge to the left, and parallel lines running front to back, however, I don't see enough consistency in the surfaces, and it looks like it is a solid material, not thin and fragile like a typical Terran shell; it looks too robust to be a petrified shell, and the base doesn't appear to match. I recall the first impressions of the Face on Mars, and the subsequent second photo taken at a different time, so that the shadows revealed the pareidolia mistakes viewed in the first. A second photo from another angle would be helpful; maybe you can snap one on a visit.

Not eye, said the blind man.

Send a Rover for a close-up, but do so knowing it a was of time and resources.

Amazing! You've discovered a rock

It is a rock.
Seriously

About the only place that ain’t got rocks is stars. To find ones that look like other stuff is no surprise at all.
