I had a quick look around didnt find anything like that. I have no
idea what your talking about. I'm bailing.

Well, if you're bailing, there must be water there, right?
That's simple logic. :-)
Seriously, I'm a amateur fossil collector, and even I thought this
formation looked a lot like a fossil:

The "blueberries" were found to be meteorite splash. Meteorite impacts
occur at such high velocity due to the thin atmosphere that the molten
rock generated by the impact gets thrown far and wide in the low gravity
and thin air, with the small droplets solidifying into spheres as they
free-fall back to the surface. The same technique was used in colonial
times to make round lead shot by pouring molten lead onto a perforated
grate at the top of a "Shot Tower" and having it solidify as it fell
through the air into a pool of water at the bottom of the tower.
Once recovered from the water the cooled shot was run over grates with
various sized holes in them, and sorted into uniform sizes by which
holes it fell through.
In much the same way, if you could run the rover all over the place and
measure the average size of the "blueberries" you found, you might be
able to figure out which particular crater their formation was
associated with, as different sized and weighted ones would travel
different distances from the formative crater in a series of concentric
rings.
