I was scouring images and something jumped right out at Me from the Image of Rocknest.
The item mentioned is about center from left to right, and a third of the way up from the bottom.
Image is PIA16453_sol64_from_Rocknest_WB-full.
Link below. ATS won't let Me upload the full image. Too large?
Then here is the item cropped and circled.
What do Ya's think? Animal? Rock? Looks like a horses head to Me... Maybe light and shadow playing tricks? I do see a dark rock under the jaw of the
'animal' and one above it's forehead, but that's not what I included in My assessment...
