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

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

Tentaculites Devonian Found in 2018 from Glenerie, NY -
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.

Brachiopod Fossil, with Tentaculites SITE LOCATION: West Virginia TIME PERIOD: Devonian Period (over 350 million years ago) Nicely detailed small Devonian brachiopod from West Virginia as well as several tentaculites impressions. Brachiopods, phylum Brachiopoda, are a group of lophotrochozoan animals that have hard "valves" on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Tentaculites is an extinct genus of conical fossils of uncertain affinity, class Tentaculita, although it is not the only member of the class. It is known from Lower -

Monday I was in Schoharie County up on the Helderberg Plateau southwest of Albany, NY. In a roadside exposure of the Manlius Formation I picked up several pieces of rock with numerous Tentaculites specimens. There were also small brachiopods and ostracods. The Manlius Formation either represents the bottom of the Helderberg Group- the lowest of the Lower Devonian or the highest formation in the Silurian in New York. Tentaculites were originally thought to be related to mollusks or worms, but now are considered more closely related to brachiopods and bryozoans.

I have recently been looking over rock hash plates from Newberry, Mich. I think the formation is Collingswood, at any rate, there are cone shaped fossils all over many of the plates I brought home, ranging from a max of 4 " to as small as 1/4 inch. I previously asked about these, and most respondants seem to suggest some kind of Tentaculites. I can see the crushed shell in most with the tell tail impression down the center indication they were once round, but I have still been tryinig to figure out if they really are tentaculites, or perhaps orthocone larva...At any rate, my point for today is

Have they ever found Permian Tentaculites?
Arizona Chris posted a topic in General Fossil Discussion
Are there any papers available or known that extend the time domain of Tentaculites past the Devonian into the Permian?
