Thought this pic looked nice and almost like an old school oil painting. I like that the pillar of the railroad track appears as if it were a continuation of the natural bluff farther back. -
I found a very odd fossil at whiskey bridge over the weekend and was wondering if anybody had any knowledge on what it could be, picture attached isn't the very best but I'm too afraid the remove it from the bag protecting it right now due to fragility, planning on properly preparing it once i get some paraloid in. BUT the fossil is about 4-5 inches long and 2-3 inches across, it is very fragile towards the end of it but the stem seems to be more sturdy. sorry again for poor picture and lack of scale, just don't want to risk further damage to the fossil yet. My only current guesses are a large

From the album: Sharks
An early Lamnid (family that includes the modern great white and mako sharks) from Central Kazakhstan. Some consider this genus to be ancestral to Carcharodon or both Carcharodon and Isurus. The latter is a tempting hypothesis since molecular clock studies place the last common ancestor of the great white and makos in this time.-

This fish has been known for decades among collectors as "Argentina sphyraena" and has only recently been described as Surlykus longigracilis. It is the most abundant fish from the Eocene Fur Formation of Denmark. Etymology: Genus named in honor of professor emeritus Finn Surlyk, The species name is derived from the Latin words ‘longus’ (long) and ‘gracilis’ (slender) referring to the body shape. References: Schrøder, A.E. & Carnevale, G. (2023). The argentiniform Surlykus longigracilis gen. et sp. nov., the most abundant fish from the Eocene Fur Formation of Denmark. Bulle

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

Made a quick trip down to bracklesham bay last weekend, with a very low tide I was hoping the beds would be exposed but no such luck! it wasn’t great on the sharks teeth finds but a very rare fish tooth and bit of turtle shell made up for that (and the views were spectacular as usual)

Would you please help me to identify these coral species, from the Eocene strata of Egypt?

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 By

Came across this paper (actually a chapter from a larger work) that was published back in 2017. Was doing an internet search and my keywords proffered this as a search result. This paper covers a bit about the early geology of the landmass that became the state of Florida but contains a more in depth look at the climate and geology over the last 50 Ma. It is not a very long read and contains some interesting graphics. I'd recommend this as fundamental reading for any Florida resident interesting in geology and fossil hunting. A really nice concise background into the geology of our state that

Hello! it’s been a while since I’ve posted anything, but I read the reports of others quite often. I visited a new spot in Virginia, on the James river, which offered some unexpected teeth. I have found much more worn similar varieties on other rivers, but this seems to be in good shape and I thought it may help me understand a bit more about dating some of the formations I’m seeing in the banks of the rivers, maybe… I believe this is either an angustidens or auriculatus, and looking for any clues from the tooth itself which may positively ID the tooth to know the age of the deposi

Bitten coprolite and other coprolites
MarcoSr posted a topic in Partners in Paleontology - Member Contributions to Science
Dr. Stephen Godfrey, the Curator of Paleontology at the Calvert Marine Museum, has a special interest in bones and coprolites with bite marks. I recently found the below fish coprolite (20 mm length) with bite marks in the Eocene, Nanjemoy Formation of Virginia and donated it to the Calvert Marine Museum. Some bite marks are infilled with Pyrite. It is by far the nicest example of a fish coprolite with bite marks that I’ve seen from the Eocene, Nanjemoy Formation of Virginia (I’ve collected over 50,000 fish coprolites (shark, ray and bony fish) from the Nanjemoy Formation over the last 25- 14 replies

Fossil shark teeth from Ukraine - What formation?
bthemoose posted a topic in General Fossil Discussion
I acquired some Paleogene fossil shark teeth from a Ukrainian fossil hunter/collector and was wondering if anyone here might know what formations these may have come from. They were found on an island in the Dnieper River near/just south of Kyiv. The collector didn't know the specific formation and described them as coming from sand alluvium. From what I can tell, these appear to all be Eocene species, though not being familiar with the local geology, I can't rule out Paleocene for the Otodus obliquus tooth at least. Any ID corrections are of course welcome as well! Otodus obliquus- 3 replies

Hello! I found these two teeth while fossil hunting at Point A Dam in Andalusia, AL and noticed that at least one appeared to be more reptilian than shark. Sizes are ~1 cm each Though it was hard to get a decent image, this tooth is extremely flat. This tooth is very round, which led me to believe it may not be a shark’s tooth. Thank you for your time!

Crabs, Ammonites, Gastropods, and More! A Texas Invertebrate Sampler
EPIKLULSXDDDDD posted a topic in Fossil Hunting Trips
Over the month of December, I've gotten the opportunity to check out several sites across the state of Texas. In my fossil interests, I have to admit that I am certainly a bit vertebrate-centric, but that does not mean I will pass up the chance to marvel at a beautiful invertebrate specimen when given the chance. For better or worse, these past four mini hunts have not really delivered on the vertebrate end, but have made up the difference in terms of inverts. I've decided to combine these smaller hunts into one report. For those with invertebrate addictions, I hope this sampler of Texas fossi -
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 -
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:

Picture heavy and pretty darn wordy heavy as well. You have been warned. The photos are by both caterpillar and me. In 2013 my wife and I went to France for a fossiling holiday. There, we met some great folks (allo coco, herve, capt nemo), one of whom came to visit us for some fossiling in 2016. Known here on TFF as ‘caterpillar’, Dominique was here again at the end of Sept into Oct for a two week Wyoming fossiling extravaganza. I took some vacation from work and did some organizing and called a few folks… and off we went. (Ok, it took a little more organizing than that, but you ge- 34 replies

I’ve had this tiny 1mm shark tooth in my collection for 3 or 4 years and am no closer to knowing what it is than when I got it. The person I got it from had no idea either. I don’t believe it’s batoid, looks shark to me. Again its tiny, roughly 1mm. It stretched the limits on the micro eye it’s so small. It is from the Ampe Clay Pit, Egem. It has some odd asymmetry going on. I have thought perhaps it was an odd Catshark of some sort but I don’t know about that now. Could it be a weird Orectolobiformes of some sort ? I don’t like admitting when I’m clueless but I real
