Why Do Pennsylvanian Rock Formations Appear as Strips?

Click For Summary
The discussion centers around sharing and identifying rocks and fossils, particularly from the Pennsylvanian period. Participants share images and descriptions of various formations, including wood-like strips and fossils found in ancient riverbeds. There is curiosity about the nature of these formations, with suggestions that they resemble Calamites or could be related to weathering processes like tafoni. The conversation also touches on the discovery of unusual orange fossils and the potential for identifying them as crinoids or trace fossils. Members express excitement about fossil hunting and share personal experiences, including finding petrified bones and arrowheads. The importance of providing scale in photographs for better identification is emphasized, along with a general enthusiasm for geology and fossil exploration.

I'd say definitely a leaf.

Thank you.

I have some large petrified bones that came out of the side of the Kansas River bank. I believe they are from a bison; back bones, ribs, and thigh. I need to see if I can find them.

I have 4 days off work, (Thurs - Sun) so I will either a/ forget this thread completely, or b/ remember and post some pictures. Is it okay to post pictures of collections in this thread even though it is called "fossil and rock IDENTIFICATION"?

Obviously the answer was a/. Forgot this thread completely.

Here is my arrow head. I had leaned down to pick up a flake that I had spotted, then noticed a piece of glass sticking edgewise out of the dirt. I decided it was best to remove the glass and throw it away in a garbage can, so I flicked it out with my fingernail and instead found it to be THIS:

Oh wow!

The weather is getting cooler and that mountain of fossil rock is calling me. There's a little road that they put a gate across and a "no trespassing' sign, but there's no fence on either side of the gate, so I assume it's ok to just walk into the field where they're bulldozing the rocks into a mountain before they haul it away. I have no intention of going through the gate, that would be wrong. :smile: I just know there are some awesome fossils in those rocks.
