It's not much to look at, but I finally got one! It wasn't in a concretion, so happening upon it was sheer luck.

Despite not really feeling up to hunting yesterday (I'm getting discouraged by my finds lately), I decided to go while the weather was still decent. And when you are not expecting to find much and/or set the bar pretty low, it makes it easy to exceed your expectations and have a pretty good trip. Here is what I brought home: First up are the odontocete fossils: My first ear bone ever: And a vert and related piece of bone that were sitting together under an uprooted tree: That's it for cetaceans, but that is pretty good for one trip for me. Other verts (not in good shape, though): Burrfish mouth plates (also not good condition): Ray mouth plate pieces and my biggest tail barb so far: Random osteoderms and bone pieces (I keep less than half of the bones I find): Various steinkerns, which I try to limit now as well, but the spiraling ones are cool: Gator tooth that was still partially in matrix: Fish jaw with teeth (maybe...let me know if you recognize it): Crab claw, I think: What I believe is my first piece of petrified wood here (again, feel free to correct me): And, of course, shark teeth: My best Great White so far: My first Angel shark tooth (shoulder and tip of crown are broken): A cool looking tooth - posterior sand tiger I believe: And the rest of the teeth (including a couple broken threshers, a barracuda, a sawfish/sawskate, etc.), which I won't show individually: As always, I wish my body could have handled a few more hours of hunting, but between little rain (no new wash-out), low creek water levels, rising heat, and health limitations, I think it turned out to be a pretty good haul. And no speeding ticket this trip! Thanks for reading!

I had a pretty good day of hunting yesterday and am planning to do a trip report, but I need help IDing one item first. When I first picked it up, I thought it was a odontocete tooth. Once I got home and cleaned it up, it looked like parts of it were peeling and there was white underneath. I have tried to peel it more, I have tried the flame test to see if it would melt or smell, but nothing seems to affect it. Any idea if this could be an odontocete or other tooth, or if it's man-made? Found in the Summerville area in a black-water river offshoot, where everything gets a black covering, but it doesn't normally peel like this. Have previously found odontocete teeth in the exact spot where I found this one. 16mm total length, "crown" is about 2mm thick. Thank you!

This is a merycoidodontid jaw fragment from the Oligocene of South Dakota, but it hasn't been identified to genus/species level. The specimen is 24.5mm long and 32mm across. Thanks in advance for any proposed IDs Othniel Just to clarify you may have seen a fossil ID thread with similar pictures to this, also started by myself. However, as suggested by FossilDude19, I will be splitting them up so as to not restrict answers. If anyone could explain how I get rid of the old thread, that would be much appreciated as well.

I found two fossilized jaw segments yesterday that I need help IDing, please. I believe the first is either barracuda or wahoo, but I've done a little research and am still not sure how to tell them apart. My guess is wahoo, based on the tooth thickness increasing as it gets closer to the root, but some descriptions I've seen of wahoo teeth describe them as "needle-like", which these are not. Jaw section is 50mm long. Tooth goes from about 1 mm thick at the point to about 5mm at the base. Found in an area that is heavily Oligocene but with a small amount of Miocene (coming from an overlying Pleistocene lag deposit). Jaw #2 I believe is cetacean... something like an echoventator. I previously found a similar one in the same creek, but the spacing between those teeth were greater (both have the double-root teeth). This creek is also Oligocene with some Miocene from overlying lag deposits. 62mm long and 32mm tall. Wet to show the double-root tooth sockets better: New jaw on left, other from same location on right: I hate to @ people if I don't have to but, from reading old posts, I think @Al Dente and @MarcoSr can probably ID wahoo vs. barracuda. Thanks so much!

Marine snails of the Lincoln Creek Formation
Neanderthal Shaman posted a topic in Member Collections
Hey all, Been absent from the forum for a while, life's been busy. I thought it would be fun to show off some of the deep sea marine gastropods I've found from 2 Lincoln Creek Formation exposures. Top: Whitneyella lincolnensis x 2, Priscofusus chehalisensis Middle : Turricula washingtonensis x 5, moon snail x 4 (either Natica sp. or Polinices sp., hard for me to tell) Bottom: Exilia lincolnensis x 3, moon snails x 2

I have seen a lot of isurus retroflexus, but this one looks more barrel shaped where the enamel meets the root.

Hello this is my second post on the forum I might be going on fossil dig this summer at my heritage guest ranch in Nebraska badlands and I was wondering what carnivores I can potentially find, and what are some of the most common finds in the carnivore and herbivore group? Also, anything else I need to know before doing this fossil hunt?

Anyone have an ID for these Lincoln Creek Formation Gastropods?
Neanderthal Shaman posted a topic in Fossil ID
Normally I would use the Burke's paleontology database to ID these, but they have informed me that it may be months before they can get their database system back up and running again. Lincoln Creek Formation, Grays Harbor County WA, oligocene. Largest one measures around 2 cm.

I found a really interesting bone a week ago. Tonight I found a Research paper. Oligocene pancheloniid sea turtles from the vicinity of Charleston South Carolina U S A A Map of where these Sea Turtles were found: A photo picture of a right Humerous of a turtle named Carolinochelys wilsoni. It is approximately 16 cm in length, My find, basically a distal half of a Sea Turtle humerus is 8.2 cm. I am feeling good tonight. Sharing the joy. Morning coming quick. Going out hunting at 5:30 AM. Goodnight, Jack

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.

Hello everyone. I am after the ID of these solitary corals. Location: Eastern Bulgaria, Rhodope Mts, south of Kardzhali Age: Oligocene, did not manage to pinpoint the exact location on the geological map, due to poor quality map. As per a local expert, the horn-shaped coral is a Placosmiliopsis bilobatus and the age is Oligocene. The species is supposed to have polymorphy; some are roundish, while others form slightly the number 8. I found a topic on a Spanish forum but I fail to understand the key elements determining the species. Through the help of Google translate, I understood that I have to create cross sections (vertically? horizontally? I made both) but I do not understand what I should observe. (Spanish text in the end of this post) Additionally, as per minedat, the P. bilobatus is supposed to have gone extinct up to Priabonian. This is the reason I started searching since one fact is against the other. The horn-shaped coral is approx an inch in diameter and 1.25" height. The discoid coral has a diameter of 1.75" and 0.25" thick. Both were cleaned with toothbrush and KOH. @fifbrindacier said that @oyo and @HansTheLoser might be able to help on this topic. I would appreciate your opinion. Thank you! "Placosmiliopsis: columnella laminar profunda / Pattalophyllia: columnilla trabecular. Solo hay que cortarle a un cucurucho su rabito y pulirlo un poco (con una muela de afilar cuesta poco), para ver si tiene una columnilla en lámina continua o una columnilla también lineal pero por una amalgama de trabéculas.... como en las últimas fotos de los links que ha puesto Elotro... ....para mi que es Pattalophyllia." This what it is supposed to be Placosmiliopsis bilobatus. There are some noumoulites or other foraminifera on top of it. Horizontal section Vertical section The other type of coral, found at the same locality.

These two (partial) bones were collected two summers ago (2021) on private land in Weld County, Colorado. They’re from a super fossiliferous bit of exposure which, based on the Oreodont fauna, is likely to be part of the Poleslide Member, which dates to the early Oligocene. These bones have puzzled me since I collected them, and I had for quite a while hypothesized that they must be some sort of ungulate metatarsal. I decided to pull them out again tonight, and having more experience with osteology generally I have decided that these look decidedly avian - specifically, the proximal ends of a right tarsometatarsus. The White River Formation has a rather diverse formally described avifauna: Benton et al. (2015) lists six genera in five families along with several different morphologies of bird eggs in The White River Badlands: Geology and Paleontology, however only one family (the Bathornithidae) has more than one described genus. Bird fossils are well-documented from the WRF, and incidentally quite a few avian holotypes have been described from the White River Formation in Colorado, so perhaps the preservational bias favors them more in that general region. However, bird fossils are simply generally rare in the fossil record due to their delicate nature, so I thought I’d post on the forum before I make a (relatively) extraordinary claim. Now, these two bones aren’t in any way associated, but they’re the exact same sort of bone. They’re identical (with the exception of the shorter one being slightly larger) - same bone, same taxon (as far as I can tell, the shorter one has some weathering). This is what puts me off even more - what are the odds that not only did I come across bird fossils, but that I independently found the exact same end of the exact same bone from the exact same avian taxon in the same week? Tarsometatarsus bones do seem to be a fairly commonly preserved isolated element for fossil birds, many genera are described based of a single tarsometatarsus and the same summer I found these I happened to find an avian tarsometatarsus in the Hell Creek Formation. But it would still be odd. Here are the pictures: I should also add that these bones are in fact thin-walled and hollow, though getting the camera to focus on the broken ends is difficult. But that doesn’t automatically make them avian, bones are fairly frequently hollowed out by simple decay. Below is an image from Benton et al. (2015), with an illustration of the holotype tarsometatarsus of Badistornis aramus, an extinct relative of the living limpkin, for comparison: My bones actually compare quite well to this illustration, though there are differences so I wouldn’t assign them to this genus/species even if I could confirm that they are bird tarsometatarsi. I also don’t think that they’re Bathornithid bones, even though those are the most famous birds from this rock unit. Of the genera from the WRF only Bathornis has a known tarsometatarsus, and it’s both morphologically very different and much larger than my bones. I’ve also ruled out the Galliformes and Falconiformes (two bird orders with representatives in the WRF), again assuming these are avian bones. I think that it compares best with wading birds such as herons and, indeed, limpkins. But this is mostly informed speculation I admit. So does anyone have any thoughts? Is there a more obvious answer for what this bone could be, or does it truly have avian affinities in your opinion? Looking forward to hearing everyone’s thoughts. References: Benton, R. C., Terry, D. O., Evanoff, E. and McDonald, H. G. (2015). The White River Badlands: Geology and Paleontology. Indiana University Press.

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.

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,
