Can't say if it is Martians processing creatures or if this is outside memorial floor sculptures displaying natures way of doing things related to Martian's creatures being destroyed by something terrible, overwhelming the Martians making it futile to put creatures into containers made of the creatures themselves! But over and over I see odd outside memorial floor sculptures as objects falling and in this photo seemingly an ocean's wave of creatures not being able to be contained there is SO much destruction. I think they are memorial sculptures in remembrance of the creatures the Martians once had. But the destruction that ruined the surface of Mars also seems to be the same one that killed off seemingly most of their creatures way back in the extreme ancient past ! Just a guess of course but seeing so many hundreds of similar odd sculptures I think I could be in the ball park of evidence seen by looking at Curiosity Rover images!
