Mystery Cylindrical Fragment - Middle Tennessee


TenneseeFisherman

Recommended Posts

This fossil was from a creek bed in Franklin, Tennessee. I have no paleontology or geology background so the little information I can give was that the rock it was in was about the size of a small toaster, and I chiseled it out (it actually popped out from the vibration).

 

Imgur Photos:

The rock was a dark grey (I have attached a photo of a different rock from the same area). I also included a photo shining a very bright flashlight through the bottom. The more crystallized part is where it was attached to the corner of the rock.

The top picture is hard to identify. You should try capturing a higher definition picture.

Hey Michael. Thanks for taking a look. I took some photos with my DSLR and you can find them here: https://imgur.com/a/cqrjaBU 

 

I'm having problems photographing the internal structure because of lighting, but it looks like a mess of opaque, white crystal structures (mostly very fine).

Thanks for taking the time to post additional pictures. Not sure exactly what it is but its definitely neat. Keep on rocking.

It is always best to load pictures directly to the Forum. 

Links to 3rd party picture hosting sites almost always go defunct. 

Posting some of the edited photos here for posterity, and those who don't wish to travel to a different website to view them.

Looks like part of a crystallized geode to me, but not necessarily from a fossil. I also can't say which minerals are involved, although calcite, quartz or gypsum may be possibilities. There seems to be some iron involved in this as well.

Is it possible it's part of a crinoid stem? Or would there need to be some hint of segmentation on the surface?

I don't believe so. If it is, then it's an extremely huge one.

I’m with Lugwigia on this one. Looks geological to me and not biological (fossil) in origin.
