Unverified but VERY interesting discovery.

The clincher just might be if they discover those mat-like structures are made of calcium carbonate or similar mineral that is difficult to explain without involving biology. I don't know if that rover can do such a chemical analysis to determine that.
If those structures are made from just sand and/or clay, they are probability made by just boring erosion.

At least here on Earth, that kind of pattern doesn't occur from just erosion.

I have only just noticed there I actually said

"they are probability made by just boring erosion."

not

"they are probably made by just boring erosion."

I didn't know probability is made by just boring erosion. Did you?

You could still use the same word, but 'in all probability made by just boring erosion'.
