Found at work. Ordovician to Devonian. It tapers so it’s not a crinoid stem

I was told this is pretty big for tentaculites.

I love this specimen. I though it might be Tentaculites at first, but I can find little reference to them in the Waldron Shale other than really old mentions of T. inornatus and T. niagarensis from the Rochester Shale of New York which is of about the same age and has many species that also occur in the Waldron. However, it may actually be a really weird bit of echinoderm stalk. It's very tiny and I'm not sure if it tapers or not as the matrix covers part of it and is stubbornly refusing to come off. It seems to be solid rather than hollow. Or ma

Devonian fishes and Tentaculites for trade
Svetlana posted a topic in Member Fossil Trades Bulletin Board
Hello everyone. I have new pieces of Devonian material - fishes and tiles with Brachiiopods and Tentaculites. Fishes not only Podolaspis - some of them are quite big and new for me; i will add their name liitle later, ok? They are found in the Ternopol region of Ukraine. I'm interested in everything - I invite you to private messages Have a nice day 1. fishes -
The only descriptions I can find of these are just that they are fossil shells and have "uncertain affinity", whatever this means. Is it simply not known what organisms they were, animal, plant or otherwise? Are there some speculations?

Hello together, I got this one as a gift, all the info I have is "rock with a nice pattern from the Sahara desert ". I am relatively sure its not a fossil, even more so after looking at the macro-fotos. Still it reminded me of tentaculites, and I wonder if there are fossils disguised by desert varnish, or if it is all pure geology. What do you think? Scale is metric, as you can tell by the ten/five small marks to a big one. Best regards, J

I knew already beforehand that this one would take me a dog's age to get it done, so I decided to keep an eye on the time. Sure enough, this took me the better part of 23 hours to get it completed. A hash plate full of lots of Tentaculites sp. from the Middle Devonian Givetian deposits at Hungry Hollow, Ontario. Thanks to Peter Lee for the photo.

Today I took a trip to a new outcrop of the Leighton Formation! My main interest in this new outcrop is to find the source of my original material. The first outcrop I visited actually turned out to be an erratic. When I first visited there in February the ground was completely frozen. I found a large piece of shale sticking out of the ground, which I proceeded to split, but the rock itself did not come out. This rock yielded about 50 pounds of material on the first trip. When I returned in June I excavated around the supposed outcrop, and found that it was in a fact

Good evening to all participants! I have accumulated a lot of local (from Ukraine) material - I decided to sort it out, and recurring fossils, or not of interest to me, offers you an exchange. Everything in the photos is one lot. Consists of: 1. Tile from Carboniferous period with fern print; 2. A fragment of the armor of a armored fish Podolaspis Lerichei of the Devonian period; 3. Tile with Silrian brachiopods and tentaculites; 4. Mollusk of Neogene; 5. A small fragment of a fossilized araucaria of the Carboniferous period with quartzite crystals; 6. 2 fragments of orthocer

How do you distinguish between tentaculites and orthoconic cephalopod fossils?

Wowowow I was very surprised to find all this amazing stuff today at my favourite river bank fossils spot of the Etobicoke creek. I managed to snag a whole lot of stuff today, some Orthoconic Nautiloids, Brachipods and what I believe to be the nicest tentaculite I've ever seen!!! The fossils are from the Georgian Bay Formation and they were found in the broken up "rock fields" next to the creek. This is going to be one of my longer posts, so I will have to split them up into section. The full haul, with the typical estwing 22 ounce rock pick (33 cm from bottom of the han

Tentaculites elongatus covered by a Fenestella crebipora from the New Scotland formation. -
The next few days are fall break for me, so I'm home from school. I decided to take the day today to explore two sites in Northern Illinois. The first is an outcrop of the Upper Ordovician Maquoketa Group in Kendall County, IL. I learned about this site from a recent trip report posted here, and found it after a little detective work. I was hoping to find Tentaculites oswegoensis, a small conical fossil of unknown affinities which is only found in this area. It only took me a few minutes before I found a few. I only stayed for 20 minutes or so, as Tentaculit

small orthoconic nautiloids versus tentaculites? What should I look for?
SteveE posted a topic in Fossil ID
Blair County, Pennsylvania (USA) Silurian... According to the map the likely guess is Clinton Formation, but my gut on site said "Wills Creek" Anyway, what do I have here? Small straight nautiloids or Tentaculites? How do you tell them apart? -
Here is a piece I saved on a recent excursion to the Devonian Cedar Valley Formation of Iowa. It looks like a thumbtack!!! I am guessing a tentaculites abutting an ostrocod, but would like other opinions. Thanks, Mike

I've received a couple nice Upper Ordovician additions to my collection courtesy of @JUAN EMMANUEL and I'm finally posting them now... (Thanks Juan!) First, is this Tentaculites or Cornulites? I wish I could get better pics. Manitoulin Fm, Hamilton, ON.
