I wish there was a scale that quantifies the degree to which an article headline struggles to attract clicks at the expense of accuracy. Looking further, I find that the JPL source article (https://www.jpl.nasa.gov/images/pia26634-curiositys-chemcam-...) used a similar headline, perhaps a bit less click-baity.
I grant that the term "dendritic," which conveys the intended meaning without sensationalism, might be too technical for a wide audience. But "dendritic" doesn't suggest a living organism to the degree that "Shaped Like Coral" (from the JPL headline) does. And in retrospect the JPL headline begs to be turned into "... multi-billion-year-old 'coral' on Mars".
But I wait with bated breath for the next iteration, titled "Scientists Baffled By Coral Reef on Mars!"

Are there examples of non-life formations like this on Earth? What are they called (how can I see some)?
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.
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

The technical term is "dendritic." No suggestion of life. The next time you see a lithium-ion battery fire, you can impress your friends by saying, "Another dendritic disaster!"
> "Curiosity has found many rocks like this one, which were formed by ancient water combined with billions of years of sandblasting by the wind," NASA representatives wrote in the statement.
The technical term is "dendritic". It's sufficiently distant from nature to avoid suggesting a living organism.
