Normal size normal dead life in Mars. I will show the rest of the picture later. I was in a hurry. (Picture tells more than that. Photoshop can see through sand and through dead animals, showing anyway each one of them, too. Don't ask me how, but a certain function of Photoshop sees through the upper parts of stone - well, i can answer anyway: light comes through it, and sand, clouds, etc. Of course limit comes somewhere.)
NASA KNOWS THE SIZE OF THESE... THEY MAY BE VERY BIG.... P.S. I may have put a wrong picture here. This is from the time, when I thought that the plump disc "in the air" is an unborn baby of an early charnia. It is not.
It is/was a mollusc. Very common mollusc in Mars, made bowls and tubs, lots of them, and very big too.
Truth, I believe, is something near that. Those look living or frozen gastropods, laying on white structure, that has forms of shoe-bottom. There are bowls too in Mars. Same or different creature/relative maybe, Im not sure.
This /\ part is a joke.
