Not too often I find myself back on the ID section lately, so I guess it's a good thing I've found something that stands out now In matrix, I found a crab claw at Whiskey Bridge (Eocene, Bartonian) in Texas. I did a brief search on the crabs of the area, but can't find anything I'm happy with that in particular shares the same rugosity as my specimen. Any thoughts welcome

Dear FossilForum members, I'm an aspirant fossil hunter and thought I'd reach out to you to possibly help identify this recent find (7 images attached, approx. 21cm x 7,5cm x 2cm), found in an Eocene layer (UK, Hampshire Coast)...flat, curved and ‘channels' running down the center of (concave) back (image 02)...could it be a rib? Any (comparative) insight you may provide would be much appreciated. Regards & thanks

Below are 10 crocodile teeth from the Ypresian age of the Moroccan Phosphates, none of which have been identified. I've numbered them to make it easier to keep track of them as they all look rather similar. Thanks in advance for any proposed IDs Othniel

Found this tooth in the vertebrate layer on my second Whisky Bridge (Lutetian, Eocene) hunt like 6 or so months ago. I just assumed it was a fish tooth, so I didn't put too much research into it at the time. Found it again while packing today and now I'm wondering what it is. I can't find any similar Eocene fish teeth in my Googling. Now that I have some marine croc teeth under my belt, I'm starting to wonder if this could be one even though I've never heard of croc material from the site. The tooth is about 9.5 mm tall and 1.5 mm in diameter on the base. It has deep striations that are densest and most uniform on the lingual side. The striations persist on the labial side, but are less dense and deep. It has a sigmoidal curvature labiolingually and two prominent cutting edges. Feel free to tag anyone who knows a thing or two about the site! @jkfoam @Jared C @erose @JohnJ Thanks!

Gastornis Eggshell
Othniel C. Marsh posted a topic in Is It Real? How to Recognize Fossil Fabrications
The item shown below is supposed to be a fragment of Gastornis eggshell, but the texture of the fragment does not look like that of any other fossil eggshell I have ever seen, avian or otherwise. Thanks in advance for any guidance Othniel -
Looking for agates and Eocene forests in central Washington
Neanderthal Shaman posted a topic in Fossil Hunting Trips
A friend of mine knows some great spots for rockhounding in central Washington near the town of Cle Elum, so we took a day to go check it out. We started by driving up Old Blewett Pass where he'd previously found some stuff representing an Eocene wetland about 50 million years ago. Sure enough, the outcrops on the pass yielded some neat finds. If you zoom in, you can see that it looks like this plant had some sort of leaf spot disease in life. More leaves, excuse the shininess of the paraloid. I think this is a horsetail. Palm frond impressions..thumb.jpg.6eaf9346dc496590e1471b3c84cc9cb9.jpg)

I work at a rock shop at the moment, and I found this labeled as a fossil insect but to me it looked liked a trilobite. My coworker said the rock is probably from the Eocene which would rule out trilobites. Any idea of what it could be exactly? I have no idea where it was found exactly

Hello everyone! I found this beautifully preserved imprint of a fish scale within the siltstone of the Cozy Dell Shale, Ventura County, CA. Middle Eocene. Wondering if there are any fish experts out here or how/if it is possible to narrow this down to any level of classification. thanks in advance!

Found in the Cozy Dell Shale. Ventura County, CA. I believe there are two specimens of Brachyura on the plate (micaceous siltstone). I can’t believe it, I screamed when I found it. We were mostly finding small fragments of legs up until this, and spent a good time searching for more with no luck. There were other shallow water fossils found in the same locality (bivalves, turrids, callista and brittlestars)

Last week in a thread by @WyomingRocks! about Whiskey Bridge, a Middle Eocene Claiborne Group site in Texas, @historianmichael asked about ostracods from there. I said I would post some pictures, so here I go. I brought home a bunch of matrix from the site a couple years ago and have broken much of it down and pulled out the larger fossils, but I had not really gone through the micro stuff until recently. I sieved it through a series of screens and found the ostracods primarily on the 60 mesh screen. I have only gone through a tiny amount of it, but wanted to answer his question as I tend to wander off in all fossil directions and who knows when I'll get back to Eocene Ostracods - haha. I picked over two dozen specimens from several different species out of less than 1/2 TBSP of matrix. I wonder what all is in the quart bag of it that I have!! Artusy in his thesis (see below) recognized 46 species of ostracods, I have a long way to go. A few years ago @jkfoamposted an ostracod or two from this location in this thread: http://www.thefossilforum.com/index.php?/topic/11079-the-arthropod-that-cant-get-any-respect/page/2/ There may be other posts on the forum as well, but Eocene ostracod threads are not a huge topic! I am not an ostracod expert by any stretch, so others that are more knowledgeable (like @Acryzona) can feel free to correct or update any of my ID's. The literature that I found dealing with ostracods from this site is limited and somewhat old, but that is what I have. I'm sure there are more recent publications on portions of the fauna, but I have not tried to wade through that. I primarily used: The Treatise on Invertebrate Paleontology Part Q (1961), a thesis by Raymond Artusy (1960) Ostracoda of the Stone City Beds at Stone City Bluff, Texas, Bulletin 114 of the Mississippi Geological Survey by William Moore (1970) The Jackson Eocene Ostracoda of Mississippi I know some of the pictures are not totally focused, but unfortunately at this magnification, there is a pretty limited depth range that is in focus until I learn how to do photo stacking. I hope you can get the idea of what they look like though, some of them are really intricate and wonderful looking. The last few pictures are really intricate specimens and I'm sure with some effort, I could get a more precise ID, but the differences are all in the details of the ornamentation and subtle shape differences and I haven't taken the time yet to master that. Enjoy!

Ancestors of Modern Horses Had Hooved Toes Instead of Single Hoof

I had went on a hike last year out in the badlands here in southwest Wyoming and stumbled across this turtle nestled up on a small peak. About a month ago, I took the same hike to retrieve what I had found ( horrible hike to pack a 50lb turtle on my back ha) and I was seeing if anybody might be able to tell me more about it by chance?

found in an Eocene formation of mostly chalk. the stones of the formation are chalk with a lot of sand and other grains. very fragile and I think its a bone. can any of you help me understand what bone is that and what animal did it came from? about 2 CM long.

Hello. I have been working on properly cataloguing my old fossil material and was wondering if anyone might have any ideas about the origin of these two fossils from Point A Dam near Andalusia, AL. I know they don’t have many descriptive features but figured I might try. Based on shape, I think 1 might be part of a ray mouth plate, lost on 2 completely. Also, my apologies about the image quality; hopefully getting a phone with a better camera soon. Thanks! 1: 2:

I received this piece without any data. Can anyone please confirm that this is from the Green River Formation in Wyoming, and maybe add more specific location/strat detail to that if it's possible to tell? Should I assume it is from the usual place in Kemmerer... and which layer? Or could it be from a different spot entirely? The ID of the fish would be appreciated too. Sorry about the crummy indoor pic... I tried to get the color balance close to reality.

Hello, I've been prepping this Diplomystus dentatus from the green river formation and I noticed something odd seemingly "inside" the ribs. At first I thought it was an extension of the pectoral fin, but it looks quite different and seems to be on the other side of the ribs. Any idea what this could be? Some sort of gut contents? PS. The fish is about 5 inches long
