Martian Archeology?

[Ai52487963]

Maybe this isn't as feasible as I'm hoping, but if very big organisms existed on Mars at some point during its water-laden history, would it even be possible that we could find fossilized remains of some of these creatures? With the lack of geologic activity in "recent" Martian years to shake up the bones of some hypothetical creature, would the soil itself erode, say, a carbon-based skeleton over the course of a billion years?

That would be martian paleontology...

And yes, though I doubt scientists expect to find life evolved that far, fossilized microorganisms are a realistic possibility.
