Native American Carved Stone?

[Wandermore91]

If this is erosion could someone please explain the intricacy and symmetry? I’ve shown this rock to a couple of people who both said it looked like it was carved, and possibly a representation of lightning or deer antlers. Either way, I found this rock at a site where I know they were present. I have grooved fishing weights from the same area. I believe this is some sort of rock art, if it didn’t serve a functional purpose. I am ready for the influx of “no artifact, natural rock” and “just erosion” but please consider other options here. The bottom of this stone looks like it may have an eroded look to it but the opposite side looks chipped away. Regardless both sides have a “spine” where the details seem to stem off from. If it is natural it is the most unusual product of nature I’ve probably ever seen. The rock is about a foot long and a few inches wide. Any input appreciated on this, looking for someone who knows rocks more than artifacts.. Thank you!

Sorry, but yes that was done by Mother Nature and erosion.

Mother nature can create some wild pieces. The first pic reminds me of the crinoid stems we have here.

Speaking of symetry and intricity think of a crystal and how easily Mother Nature form them.

imho what you see is material that is harder than the material surrounding it, and it erodes at a slower rate.

The rock itself appears to be sandstone. My guess is the higher sections are cemented by quartz grains, which resist weathering very well, and the lower portions are cemented together by a less resistant cementing mineral. So you end up with what quito is talking about, differential weathering....
