From the album: My Echinoid Collection
Periarchus sp. Castle Hayne Formation Late Eocene (41-33 Ma) Holden Beach, Brunswick County, North Carolina, USA Self collected in September 2023 A highly unexpected but exciting find, I came across this chunk of Castle Hayne material while searching the beach for Cretaceous Hardouinia mortonis specimens. The tide and surf was particularly strong due to an offshore tropical cyclone, which made it difficult to find the Cretaceous echinoids, but was bringing in large stones and other things. As best as I can recall, this is the first Castle Hayne formation material I've seen on Holden Beach. The chunk is fairly hefty, and is at least 30.5 cm (12 inches) long. There are a number of Periarchus fragments in the material, and there is one other visible specimen that is only missing about ten percent of the test. I am unsure of the species due to the periproct being obscured. I have little doubt that there are probably more specimens in the center of the material. The chunk also has numerous bryzoan fossils. -
My girlfriend and I found this ray tooth plate the other day at the bridge, was wondering if anyone could get a positive ID on it? Below are 3 pictures one with a ruler for scale and 2 nice pictures of it on top of some petrified wood I found in town.

Hello all, this is my first post, and is an ID task. I found this on Braklesham beach, which has a few offshore Eocene clay deposits rich in shark teeth and Ray pallets, as well as turtle carapace. I'm not sure what this is, but it is very similar in size (1.5cm) and shape to squid beaks I have dissected in biology, and was wondering if it might be the beak of a cephalopod. I'm sorry for the poor photos, I'll try get some better ones with my camera. All the best, Tsav.

Hello! I just completed my second trip out to Point A Dam in River Falls, AL and found a couple of interesting things that I cannot seem to ID. Due to traveling, I only took a few pictures and had to use a coin for scale before moving to my next destination, so I apologize for the lack of quantity and quality of my photos. When I get time, I can take more images of the samples below upon request. Thank you! 1: I’m leaning toward Angel shark (?) 2: Legitimately do not have a clue… Maybe stingray related as it is long and cylindrical but it has confounded me. It does have a hole through the center that was difficult to image, presumably for soft tissue. 3: Once again, I don’t have a clue. The bottom of these pieces are smooth and concave below the central “peak.” 4: Miscellaneous pieces. Very well could be nothing but figured I may as well post them.

Took my brother out this Sunday to do some fossil hunting in Monmouth County, NJ. Rainy day, but it didnt stop us from spending a good 5 hours in the water. We started out at Big Brook, and spent most of our time there. Everything from the Belemnite down were my finds, which included a Crow Shark tooth (Squalicorax), a few Gobblin Shark teeth (Scapanorhynchus), several Enchodus teeth, a small section of Ratfish jaw (Ischyodus), couple crustacean claw pieces, a Mosasaur tooth fragment and an unidentified jaw fragment (brown piece, bottom right). Coin is 21mm. The items left and right of the coin were found in a different area in Monmouth, with deposits from the Eocene and Miocene. This was my first time here and I had a great hunt despite being there for only about an hour. Definitely need to go back and spend more time here. Big thanks to another collector for helping me with ID's. I believe the large teeth are Sand Shark (Carcharias). The teeth L & R of the coin are Tiger Shark (Galeocerdo) and the smaller tooth to the left Lemon Shark (Negaprion). Unsure of the small tooth to the right. The Sand Shark tooth to the left is my largest tooth find to date, despite missing the root, measuring in at almost 3cm. Gives me hope there is are complete examples that size in the same area. Thanks for looking, and feedback good/bad is always welcome!

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)

Hello All, I am a long time 'lurker' of this forum, and have been interested in fossils ever since I found my first shark tooth back in the 90s. I only recently got serious about the hobby in the last year and a half. And have spent a lot of time researching potential sites, and hunting (mostly with success). I generally hunt by canoe/kayak, and hunt in central VA and MD. Here are some of the display worthy teeth/fossils/indian pottery I have found in the last year and half. I am most proud of the Alopias, which was found in the same creek as the large warn Megalodon (5.25 inch). Goals moving forward Are to get into some new stuff, and currently need a couple more teeth such as an intact auriculatus, a GW, Parotodus B. etc.

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!
