Hey there, got a pickle for y’all. This one was given to me and it was said it was from Dakota sandstone in central Utah. Not sure if this means the Naturita Formation, very low Mancos Shale, or very high part of the Morrison formation. I was thinking it was a vertebra but with how deep the curve is I am wondering if it is a toe or extremity bone or some sort? added some closeups of it under a microscope, varied from 600x to 2000x magnification

From my previous trip to Ellsworth County, Kansas and it's located in Dakota formation, Cenomanian. It appeared as almost like vertebrae but I'm sure it's not verts. Is it by chance some form of ichnofossil? @jpc thinks it's concretionary. No disrespect to him, he's the only one who offered his opinion and I would like to know if anyone else have a different opinion.

Yesterday (Saturday, Aug. 22nd), I went fossil hunting in Ellsworth County, Kansas again for elusive Dakota Sandstone leaves and unfortunately it's mostly a bust, just like the previous trip. Despite that, I enjoyed the scenery and found some odd rocks and few fossils from new sites. A new site produced a few small plates containing woody and plant material fragments. I decided not to keep them. Closer views... Remember that interesting sandstone from the previous trip? I regretted for not taking it home so I took another opportunity and revisited the old site to get that rock! The back of this rock is quite smooth and flat, I think it would be great to have it hang up on the wall, but I'm actually not sure how I will display it. Looking at it is like reading a 3D map! It's the only object I brought home from this trip. It's peaceful out there and the views of the Smoky Hills never gets old. ...continued on the next post.

Like what title said: is it a tree limb, bamboo, reed, or is it even something geological? Dakota formation, also known as Dakota Sandstone. Dakota formation is known to produce variety of flora fossils, such as leaves and seeds. The patterns on these fossils strike me as 'flora-ish'; like these that seem be nodes and also 'bark-like' and fibrous textures. ...Continued on the next post.

I'm wondering if it's a fossilized burrow or some form of ichnofossil. Notice the depression from the opposite side of the burrow-like projection. Dakota Sandstone formation and Cenomanian in age.

I'm wondering if it's really the petrified woods. It's found in ironstone concretions from Dakota Sandstone (Cenomanian), and it strikes me as 'woody'. I'm interested in what others think. From different trip and different site few months ago, but same formation and age.

Today I had a good time with fossil hunting at the Dakota formation (early Cenomanian) sites and Greenhorn formation (Cenomanian-early Turonian) sites in Ellsworth county, Kansas. Typical view of the local countryside, but still beautiful! I keep finding these weird vertebrae-like rocks, clustered in this particular site and not other sites. I suspect it's not vertebrae but I still can't figure this out yet. These mysterious vertebrae-like rocks...reminds me of shark centrum and crinoid stems but I don't think it's them. This site is Dakota formation. I took these home just in case it is identified as fossils later. I think it's fossil vegetation of some sort. Maybe reed or horsetail? I found these jumbled at different locations but put it together and it fitted like a puzzle. I took it home and will be prepped. This is from Dakota formation. Inoceramus from Greenhorn formation. One of the best specimen of this genus I have found so far! Took this one home. Another Inoceramus, pretty good specimen! I also took this one home. Tiny fossil in the center. Greenhorn formation again. This tiny fossil, image enlarged and the ridges/grooves are visible. No idea what it was. I took this one home and will be put under the microscope for identification efforts. The storm was brewing at the distance as the cold front is heading south. It was lightning and I was at near the top of hill, the road would be impassable if wet, so it was time for me to go home! I will be posting some of those fossils on the Fossils ID section soon after it is cleaned up. Cheers!

Finding the fossilized leaves from Dakota formation (also known as Dakota Sandstone) has been one of my goals for a long time. Today I headed to Ellsworth County, Kansas, where the Dakota Sandstone are located and hunt for the fossilized leaves. Unfortunately it's mostly a bust, but I did find a couple possible wood fossils and a few interesting rocks. I didn't take anything home this time except some pictures and memories. Notice the trees following along the small stream. Interesting sandstone! Interesting ironstone concretion! ...Continued on the next post.

At first I thought it might be the cross-section of petrified trunk but upon a closer inspection, I doubt it's petrified woods. It is not silicified. I wonder if it's a concretion or Liesegang rings? I don't think I have seen something like this in person before. I couldn't get it extracted because it's embedded in the bedrock.

Is this even a fossil? Ichnofossil? I'm stumped by this weird pattern. I found this ironstone in my parents' gravel driveway. Gravels were recently obtained from the local sand pit company here in Salina, KS., so I'm pretty sure this stone was transported in the river from Kiowa or Dakota formation (Albian) before being deposited.

I'm guessing it's an iron concretion and not a fossil, but I would like to make sure. I have never seen anything like this shaped like a spikeball or flower, except in crystals. Fossil or not, I took it home because it's so interesting! Dakota formation and early Cenomainian. This formation are known for fossilized plants, leaf imprints, and petrified woods.
