Ancient remains on Mars: Head of animal figure with horns and other strange anomalies

The latest image captured by Opportunity mars rover shows a rock formation that hides some remarkable objects.

Without doubt some of the objects are just rocks but there also objects where you can put a question mark how it ended up there.

Below I have marked the objects in the original image.


To see the first three objects, I have put the images upside down.

1. Large image upside down shows a head of an animal figure with horns, probably remains of an ancient statue. 


2. Large image upside down shows a rock that looks like a sinister head. 


3. Large image upside down shows a head and corpse of an animal like a deer/antelope. It looks like the animal died recently. 


4. Image shows a small statue of an animal figure. 


5. Image shows a face carved into a rock.
