I've got this piece of Oligocene amber from Montana which has a very odd hole running straight through it. I at first though that this could be from where the resin seeped out around a twig of its tree and the twig eventually rotted away, leaving this hole. Do you think that could be the cause? The hole was filled with dirt before I cleaned it.

A few odds and ends I picked up on Sunday from Twin Beach, Washington. The Burke Museum Paleontology Database is still down (PLEASE BURKE, GET IT BACK ONLINE!!!), so I can't really ID the snails right now, but one of them is clearly a moon snail, and if I had to hazard a guess, the big one is maybe some sort of spindle snail? Prepping it was very easy and zen. And of course a Callianopsis clallamensis ghost shrimp that the beach is so well known for. Till' next time!

Found ex-situ, so I have included both Oligocene formation possibilities (Chandler Bridge Formation and Ashley Formation). References: Cicimurri, D. J., & Knight, J. L. (2009).

Hello all, I have some teeth that have accumulated from some past trips that I haven't been able to find an ID for. I appreciate any input people might have. First, there is this fish tooth from the Moodys Branch Formation (Eocene) of Mississippi. As difficult as bony fish teeth are I thought I'd see if anyone could ID this one since it is quite a nice tooth. Closest thing I've found is Eutrichiurides but it isn't as compressed as figured plates. Attempting to show the double carinae. The following teeth are from the Byram Formation (Oligocene, Rupelian) of Mississippi. I figured Carcharias on this one.

In North Florida, we looked for Blue Agatized Coral and found some in a stream. At home we cut and polished them. We put together a video showing the whole process: https://youtu.be/aae9XqJPMCU best wishes, Lloyd

Micro matrix for trade- Old Church and Hallencourt
fossilsonwheels posted a topic in Member-to-Member Fossil Trades
I have small amounts of micro matrix that I’d be willing to trade. My preference would be to trade both to one person for ease of shipping. Old Church Formation, Oligocene Virginia I had separated some matrix before searching any of it specifically to trade some and rethought it after I found a Pristiophorus rostral lol I decided to not search it though as the intent was to give somebody else a chance to have fun searching. It is very productive matrix. I can see a couple of shark teeth in there. Among the possible shark teeth are Notorynchus, Squatina, Carcharias, Alopias, Isurus, Galeocerdo, Galeorhinus, Sphyrna, Carcharhinus, Pachyscyllium, Hemipristis. You are also likely to find a few Batoid teeth like Dasyatis, Raja, and Myliobatid. I really enjoyed this matrix. It’s a pretty diverse Oligocene fauna with good density of shark material. I did a report here on my searches for reference. Hallencourt France, Cretaceous Tiny matrix, tiny and very sparse fossils. You’ll find some invertebrate material. You may find a few fish teeth. The shark fauna is really cool, pretty diverse BUT there isn’t a ton of teeth. You’ll find broken Anomotodon. You’re very likely to find tiny Chiloscyllium teeth. There is a publication on this fauna and other possibilities like Synechodus, Scyliorhinus, Carcharias, Heterodontus, Palaeotriakis exist but again it’s really sparse. There is also a report on my searches of this matrix. As far as I what I’d like to get in return, I’d say interesting shark and/or batoid teeth. Some of what I’d like is below but I’m open minded and it’s not physically a lot of matrix Pristiophorus Heterodontus Squaliformes Catshark teeth, particularly Cretaceous and Miocene teeth Micro matrix that has shark teeth. I don’t need STH, Calvert, Post Oak Creek, Aquia, Atco, Cookiecutter Creek, Peace River,

Our friend @sharkdoctor sent us some micro matrix from the Old Church Formation in Virginia. This is our second batch and the first was fairly sparse but we did find some cool stuff. I haven’t searched much of this matrix but it’s already produced some nice teeth and has a better density too. There isnt, to my knowledge, any descriptions of Old Church material so my ID’s are just best guess. First pic- a beautiful little Galeorhinus tooth. Second pic- a really awesome Sphyrna tooth, maybe S. media. Third pic- a colorful Galeocerdo, I’d guess G. aduncas. I will update this I go.

another rare and very small pipefish, Doryramphus, from famous pit Frauenweiler near Wiesloch / Darmstadt / SW-Germany. Oligocene. Might be these fishes had been not so rare as it was told, but they are tiny (1 - 5 cm), slender and not easy to discover. This one is around 4 cm-

My daughter and I have just returned from the Isle of Wight, we hunted a couple of times around Yarmouth and Bouldnor where the beaches are full of Oligocene material. We found lots of pieces of croc, turtle and sturgeon as well as a small fish vert. We also found this which I think is the distal end of a mammal humerus. While I don’t think Pleistocene can be ruled out, the bone is heavy and feels fully mineralised. Tapping it with a spoon sounds like hitting rock as opposed to bone and it feels a lot more like rock than any of the ice age bones in our collection. I have read that as well as croc, turtle etc there were Oligocene mammals such as Tapir known in that area. Can anyone identify what the bone may have come from? Also, do I need to do anything to preserve it? Should I soak it to remove any salt and then coat with paraloid? Thanks for looking IMG_2370.MOV

With the start of 2023 I decided to take a break from my long running prep project and prepare out something smaller to start the year off. I collected several of these C. clallamensis shrimp nodules last January and in my previous experience they tend to prep well. This was one that I had split on the beach so I knew that there was a large-ish claw and hoped nodule contained the rest of the arm also. The nodule before prep Unfortunately this nodule didn't contain an arm but rather a bunch of fragmentary shell remains and one large disarticulated claw, but the claw tip glued back on nicely and I decided to have a play with shaping the matrix resulting in an interesting bowled out effect. In total the prep took about 3.5 hours with my Ken Mannion TT pen and I'm quite pleased with how much I managed to undercut the outside of the nodule without breaking it away. While not the best shrimp this was a fun prep to start off the year. Thanks for having a look

I was inspired by another WR post and thought I'd share what I was working on today. I had a small rock with a sliver of rostrum showing (white bone). Poked at it a bit with a microjack and it just kept going. All scope work so far. Was hoping for a cranium but no such luck. No nasals either. Now I'm trying to decide how it should display and how I was to expose the cheek teeth. Here it is sitting flat. And I'm thinking I will stand it on edge for display, like so. Will have to remove the matrix on top and prep out the cheek teeth to identify. My initial guess is Paradjidaumo though based on the short incisors and size.

Hello, I think I found my first serious fossil!! Up until now, I always found invertebrate and plant fossils like echinoids and giant oysters, but recently after fossil hunting last week at my favorite spot, the San Sebastián Limestone, I stumbled upon something absolutely incredible. I was rushing to get home cause it was getting dark and the river was getting pretty cold, but I tripped over this huge stone. I saw the shadow of something stuck and quickly put it in my backpack, swam and crossed the river and bought it home thinking it was some kind of fossilized wood. It is very, very heavy. However, after checking it closely, it looks like it's actually a bone! Those are extremely rare in the island and I've never seen one, so I'm hoping some bone experts can help me properly identify this fossil.

Hi all. I was was hoping to get help with this one from the community. It was found in-stream near an outcropping of Pittsburg Bluff in Clatsop County, Oregon, and downstream of some Astoria Formation, both marine sediments. I have found mollusks and arthropods in the same collecting area, usually in very hard concretions. To my knowledge no marine vertebrate fossils have been found within the Pittsburg Bluff Group so if it is vertebrate I'm thinking it came down from the Astoria Formation southwest of the area. It looks and feels like bone, and is extremely porous (tongue sticks). Or it may just be a pseudofossil. Either way, thank you for the help.

What I believe to be a carpus of the major chela of a ghost shrimp. Not an unusual find for me, but this was found near an exposure of Pittsburgh Bluff formation where previously I have only found them in Astoria formation.
