Important Notice: Please look close and notice that there is an impression that of a very odd arm and head seemingly trying to show how rollers are being scattered and going every which way. But as in so many of these outside memorial floor sculptures, they seem composed of fish's that make up an odd head or arms that are made up of fishes with!
Hardly ever do you see heads that look like a human head. I really don't think that these odd heads that are in so many of these floor sculptures are what looks like Martians. But the extreme ancient catastrophe was so all encompassing that the fish-look seem to be a priority in Martian's form of expression in their outside memorial floor sculptures! So much so that below photo seems to show a very odd arm trying to hold on to a "roller" to make it stop. But in order for us to understand, I think they made a half circle to show the odd arm is trying to stop it from rolling more creatures to be flattened due to the planet ending catastrophe in extreme antiquity !
The analysis I use for the photos and imagery are not mean't to be exacting, only to get you closer to understanding that there is intelligent life on mars (martians). Many of the rocks you may think are rocks, are in fact highly designed sculptures, mechanical objects etc.
Nasa is trying to leak out anomalous imagery with out of course talking about it public! Though most images have been doctored, Nasa is trying to humbly and quietly nudge us along with out going too public about it vocally. Though it is work and painstaking effort to find objects in the images that have not been altered in some way!
