Incredible!

The spheres at the Spirit site appear as dunes, but there
are several pics showing sizable rocks on top of the
these dunes.

And what the 'ell is this?

And does this pic show the spheres are eroding away and uncovering
a basalt rock?

It looks to me the spheres at the Spirit site are different, they seem
less uniformly
spherical and the broken pieces seem to be missing. They appear more like
the
spheres eroding out of the sedimentary rock at the Opportunity site.
So I would speculate the Spirit spheres are the fossilized version being
uncovered by erosion.

And in this pic the shapes appear to be determined by contact
with each other, especially in the upper left. Where a couple
are u-shaped around another.

I think this puts a big damper on the idea they formed in
the atmosphere as fallout, but more likely underwater.
The dunes at the Spirit site might be from ancient
wave action, not wind.

These are life forms, I'm more convinced every day.
