I found this Ammonite a couple weeks ago and I wanted to prep it. I dont know how to prep the inner whorls and it seems kinda hard. Im Using a Dremel 290 (factory tip bc the Zoic tips doesn't arrive yet) Any opinion or tip will be good welcome!

Hello ! I got this fossil from my friend. It's from the Australian Museum. What species does this fossil belong to? I hope everyone be careful of abnormal weather. Thanks.

Hello everyone - I am getting into fossil collecting and recently had a trip to Charmouth, UK. I would like to try to ID some of the pyrite ammonite species I found there. I've written what I thought they might be based on information and photos I have found online but I am very much a beginner so I would like some help checking them. I've also included another pyrite fossil which I'm not sure what it is at the end. 35mm long paperclip for scale. Any help would be greatly appreciated! Thanks! 1: Both Promicroceras? 2: Not sure - maybe Echioceras? 3: Oxynoticeras? 4: Another Echioceras? 5: No idea - looks like a fragment of something conical with horizontal bands around it which can be sort of seen in the first image - mostly encased in pyrite.

I have 3-4 spots (duck creek, Grayson, Fort Worth formations) I haven’t yet revisited since it rained that are really close to my house. I’ve been to the same conlinoceras spot 3x and this was my last visit until we get heavy rain/erosion again. It didn’t disappoint! Funny how I can walk by the same spot 3x and find things I missed. Haha! I’ve seen ammonites missing chambers before, but this little one seems to have indentations that might have been there originally, like from bite marks or something. What do you think? Just my child-like imagination? the nice looking white calcite specimen missing part of itself is from another larger creek that my primary spot feeds into more upstream. Tarrant County TX.

hello, does anyone know what is this? I know it's from southern Germany or Austria mountain areas. Got it together with several ammonites and sea floor sediments parts. The possible fossil is around 9 cm long and 5 wide. Thank you

First one I want to confirm ID, it's still a work in progress, Calycoceras Tarrantense? The other one I just wanted to share, I haven't seen such unique preservation and view of the siphuncle and think it's facinating.

Beginners luck: one of the very first ammonites I found in March of this year is apparently quite rare, in fact, I’ve never found one since - Graysonites lozoi. I believe the Grayson Formation, where I found this, typically only has nautiloids, and some nice oysters. It’s not in great shape, and I haven’t even tried to remove any matrix, but it’s still an interesting ammonite that looks a bit different from the typical Mortoniceras ammonites I find. Location is Tarrant County, actually in Burleson where I live.

I want to thank @AncientEarth for the wonderful prep work on this specimen. I'll be excited to pick it up next month. Aaron does really good work and I will definitely use him again in the future.

So i found this Ammonite few months ago. I want to prep it but there is some factors that made me think its quite hard/impossible with the tools that I have right now The first thing is how sticky is the matrix (I dont know if you can see in the image) but the matrix is really sticky and thick in some places. The second thing is the size of the specimen, and its not even complete. Thats the principal thing that made me want to prep it, but I dont know if is possible I have the Dremel 290 with the Zoic tips

A new find in Tarrant County TX and a question…
Shaun-DFW Fossils posted a topic in Fossil Hunting Trips
I had to return some clothes to the shopping mall yesterday. Rather, I volunteered to return them with a spot in mind that is right next to the mall where I found some big boy ammonites, eopachydiscus upwards of 15-19inches. The rain uncovered a nice one that was in loose soil. For some reason, many of the ammonites in this creek are really worn down in the center. How do you all handle removing matrix if you’re concerned about leaving a hole in the middle? I’m thinking I can simply “file” down the matrix until it looks like it’s as far as I can go using some sort of air abrasive tool? This one is 15.5 inches and I like the symmetrical shape and visible ridges. Many eop. I find are smooth around the outside without the wavy appearance. Different species?

Hi Fossil Forum, Someone gave me these ammonite fossils that they claim were found in southern Ontario Canada in the early 1900’s. I looked around and the only ammonite fossils from Ontario I saw were small pyritized ones. They look real to me, as you can see structures (of aragonite?) that fakes don't normally have, but none of my other ammonites I own have this ridge down the middle that makes it look like it came out of a mold. Most seem to be of one species that's ridged but one is also smooth with no central ridge. Let me know what you guys think, genus wise, and if you think they are from Ontario. Thanks, Alicia

Seller says this Ammonite has a label saying it's from Topanga Canyon California. However the Topanga formation is Miocene and I am unsure if there are Mesozoic formations nearby. Seller couldn't give me a formation as it's from an old collection.

Well, today my Zoic tips arrive so i decide to continue the preparation of this Ammonite. Its not finished yet but im really happy with the resultas. the rock pop quickly and easily. The inner whorls are preserved, that's the best thing for me. Its my very first real preparation project, so im very excited of the next one. Any tips to keep going with this specimen, general tips or commentary will be well recived

I recieved these ammonites, along with many other items, from an old collection. I have no idea where they come from, although the previous owner was Dutch, so I'd expect them to be from somewhere in Europe. I also suspect that both pieces come from the same place, as they have the same shell imprint in their matrix. The collection also came with heavily pyritised nautilus fossils (some of which had pyrite disease) which may or may not come from the same location. Ammonite 1: I tried preparing this one, but the matrix contains too much pyrite.
