I certainly see the dendritic nature of the rock but I am wondering if there are rocks found on Earth that look he same. Most of the examples of that sort of thing are more 2D patterns.

Just some images of what I am talking about: https://duckduckgo.com/?q=dindrite+rock&t=ffab&ia=images&iax...

could be formed by something like a stromatilite(s), which are presumed to be the most ancient life forms to 1 leave macro fosils, and 2 are an existing species today or just some blobby rock's in any case, it's one more reason to go to mars, other than of course we dont realy have anywhere else to go, and with 9 billion people side eyeing each other, were going

This is what I was looking for.
