Notice how Gobekli Tepe's T Pillar #43 (top horizontal cross section) has creatures next to each container. And Curiosity Rover has these odd containers all over the place and seeming creatures being put into them.
I think on a basic level the answer is clear, they are (on Mars as well as Gobekli Tepe on earth) memorials dedicated to the loss of the Martian's creatures from when they were on Mars but mostly died off because of a catastrophe that ruined the Martian surface and led the Martian civilization to make cities and go underground in order to survive in extreme ancient times! There really is a theme of Martians being haunted by not having their creatures even currently with them, thus making incredible outside floor sculptures, again in remembrance of their beloved creature-animals etc.
Just on a basic level think about it, why are animal creatures etc. displayed SO often on so many Gobekli Tepe T Pillars? Simply because they lost them and they dnever returned. Their anguish must of been so strong especially after it happened when the destruction was so devastating and creature life wiped out on the Martian surface!
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!
