Hi everyone, my son found a very cool fossil today which I think is a fish but wondered what others think? thanks Brad

Very young fish (27mm) in which the scales have not yet ossified. Juvenile specimens of Diplomystus dentatus can easily be mistaken for juvenile specimens of Notogoneus osculus. But juvenile Notagoneus can be easily recognized by the larger skull and the position of the anal fin, which is set far back. For comparison a specimen of a juvenile Diplomystus dentatus preserved on the same slab: Taxonomy from Fossilworks.org. Revised generic diagnosis from Grande and Grande 2008, p. 10. "†Notogoneus differs from all other genera in the family Gonorynchidae by the fol

A few weekends ago, driving to A&M for a gymnastics meet (I'll be transferring there this fall!), I noticed a very familiar looking bridge from this forum, and the sign confirmed that barely 20 minutes away from the heart of campus is the famous Whiskey Bridge. I had no idea, so this was a very pleasant surprise. On the drive back, I decided to hit the bridge bright and early. Found a few cool inverts that are easy enough to ID with the good guides for them, but the sharks of whiskey bridge seem to be poorly written up. In fact, I couldn't find any good guides that compiled mo

The assistant curator of paleontology at the Virginia Museum of Natural History is researching squamates, which includes snakes, from the Eocene Nanjemoy Formation of Virginia. A couple of friends and I have given him recently a large number of snake vertebrae, mostly from the sea snakes Palaeophis casei and Palaeophis toliapicus, from the Nanjemoy Formation of Virginia, to support his research. We will donate the specimens needed for his research. He is definitely interested in my large Palaeophis sp. vertebra in the below pictures:- 6 replies

Eocene lignitized seeds/fruits from Virginia
MarcoSr posted a topic in Partners in Paleontology - Member Contributions to Science
I just sent the below Eocene lignitized seeds/fruits from Virginia to a paleo botanist at the Smithsonian Institution, who will use a new CT scanner that makes this material vastly more interpretable than before, to study them. Since these seeds/fruits are not mineralized like petrified wood they should have been stored in Glycerin with a bit of thymol, which is an anti fungal agent, rather than in gem jar cups. You can see the discoloration of some of the foam from deterioration of the seeds/fruits over the 15 to 20 years that most of them were stored. I hope that they are still useful. I -

Shark, Ray and Bony Fish Vertebrae
MarcoSr posted a topic in Partners in Paleontology - Member Contributions to Science
I have several thousand well preserved shark and ray vertebrae from the Eocene of Virginia. I also have many more thousands of bony fish vertebrae from the Eocene of Virginia. See the group pictures in this post. The paper plates are 9 inches in diameter for size reference. There is very little written on fossil shark and ray vertebrae that I can find in the literature and what is written is scattered throughout a good number of different papers. I have a unique, extensive assemblage of many different vertebrae types and forms which represent the fish species from the Eocene of- 24 replies

I was walking around an antique store here in Western NY this past weekend and found a ziplock bag of shells/coral for $7. The bag had a very nice Flame Helmet shell from the Caribbean, some pieces of recent beachworn coral, and this fossil wood section with polished end. Size 68mm x 40mm. The outer "bark" is chalcedony and the wood seems to me to be cypress or palm, possibly Eocene in age, I'm thinking US locality maybe Wyoming or ? I'm not an expert on petrified wood and will appreciate any help. Thanks

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. -
Went out to central Washington with some friends yesterday to check out some fossils spots and grab some agates (trip report forthcoming). Found this on Old Blewett Pass near Cle Elum. This is either from the Chuckanut Formation or the associated Swauk Formation, both Eocene. It was found among leaf and palm frond fossils. Any ideas?

I’m making this post because I don’t think many TFF members are familiar with Pelagornithidae bony-toothed birds. I first became aware of bony-toothed birds a few years ago when the son of my friend Gary found a beautiful jaw of a bony-toothed bird in the Miocene of Maryland. However, I really wasn’t expecting to find any specimens in the Eocene of Virginia that I regularly collect. However, recently Gary, who I collect with on a regular basis, found a piece of a bony-toothed bird jaw in the Eocene of Virginia. My friend Mike then showed me a really nice specimen that he had also collected

Selling Real for Fake Fossils?
Lucid_Bot posted a topic in Is It Real? How to Recognize Fossil Fabrications
Everyone I've encountered on this site has been very helpful, so thank you. However, I'm in need of more help. For the last year I've been collecting real fossils in the field and selling some to pay for more exotic rocks. In a recent post I found that my Solnhofen shrimp is, if not totally, mostly fake. Now I'm quite suspicious of my entire purchased collection and was hoping you could help me identify fakes. The first two pictures are apparently Priscacara, Green River Formation, Eocene; the next two supposedly Asteroidea, Morocco, Ordovician; the last three supposedly Triassic, Arizona petr- 25 replies

My first fossil hunt post. Yesterday (May 29 2022), I went down to the Florissant Fossil Quarry in Florissant Colorado. Its about a 45 minute drive west of Colorado Springs. Its a very well know site partly because of the very well preserved fossils and relative abundance but also because of how easy it is. You pay a small fee and they give you the tools and you pick up shale and start splitting, that simple. You're guaranteed to find something if you try. If you are in the area I would definitely recommend stopping by, its just not really on the way to any popular stops. There is also th

I noticed this fossil in the limestone at the base of the great pyramid whilst on holiday. Reading online there are quite a few Nummulites in the rock of the pyramids themselves but not much information on larger finds and unlike the quarried and transported stone of the pyramids themselves this was seemingly part of the natural giza rock forming base around the structure. Im very much an amateur at this but out of pure interest I was wondering what you all may think of it?

Whiskey Bridge - Texas Eocene - A Day on the Brazos
JamieLynn posted a topic in Fossil Hunting Trips
A couple of hours drive from me is an amazing spot to collect Eocene material. It's on the banks of the Brazos River (more properly, the Brazos del Dio River-The Arms of God river! My parents wrote a book on it: Exploring the Brazos: From Beginning to End). I've been to the site a few times, and always find an amazing amount of lovely little shells and such. I had the greatest luck this time though, finding a large shark tooth! I wasn't even aware that you could find shark teeth out there. I had found a cuttlefish prong there on a previous trip which is still one of my all time favorite finds- 28 replies

Hi everybody! I've been in the process of trying to identify the types of mollusks I found on a recent scouting trip out to the Lincoln Creek Formation. I very much don't know what I'm doing regarding identification or preserving, so any tips will help! Regarding the bivalve, I'm wondering what I can tell with the ligaments. I feel I can safely say it's a taxodont, but I don't know where to go from there. I think that this fossil shows the imprint of the inside of the shell, and I think that the outside is well ribbed, but I think that from impressions left near this foss

These represent some of the earliest sharks from this genus, which is now quite successful and diverse today. -

Right up there with the Conasauga Shale further north, the Late Eocene Tivola Limestone is a formation that has become one of my absolute favorites to hunt over the course of my visits to the formation. 2 months ago I went there and got a good series of photos and as always good finds, but I neglected to actually post a proper field trip report. It was the first time in a good while that I had gone fossil hunting, something that I had been absolutely craving for a while in the midst of a sea of university exams that lied ahead in the coming month. When we arrived at the

Hi. This was found in a spot in the SF East Bay area, CA, right on the border between Eocene/Domingene and Lower Cretaceous sedimentary. Spiral-shaped gastropods and bivalves are dominant, but I found this oval one shown in the middle of the pic below. It's a familiar shape, maybe a Limpet? Any thoughts appreciated.

Today I found out why Whiskey Bridge deserves its reputation.
Jared C posted a topic in Fossil Hunting Trips
I drove to college station to meet up with my future roommate today, and on the way back made the obligatory stop by Whiskey Bridge. This was my second time there, and.... I'll just let this tooth speak for itself. It had me on my knees. Flawless. Striatolamia macrota Stone city formation (Middle Eocene) Another angle, as well as my other finds today:- 11 replies
