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 -
Pretty sure I found a shark tooth in Washington State today
Neanderthal Shaman posted a topic in Fossil ID
I was at Olequa Creek in Vader, Washington today. The creek has Cowlitz Formation exposures, but because of the rains causing high water, they're mostly inaccessible right now. However I did happen upon a little outcrop with this nice piece of clam sticking out. Burke Museum database has been down for months, so I don't know the species. I pulled it loose, and was a little dissapointed that it was fragmented. However when I flipped it over, I was surprised to see what looks like a shark tooth. I remember seeing some squaliformes in the Burke datab -
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

Hi...For some reason this scallop doesn't look like the typical Calvert Cliffs Chesapecten nefrons. Its small, black stained, and appears in MY eye to be taller than normal. I don't have a good nefrons to compare the length to width ratios but it just SEEMS different. (26.6mm widest x 29.16 tall not at a diagonal). It was found within the same grit as the efrons pieces, the shark vertibrae, the oyster shell etc. that we found. From the southern end of the exposure at the State Park tiny beach. Are C.efrons the only eocene scallops found there? Is it a morphological difference due to its assum

Recently, after going to my favorite fossil store, I aquired a Otodus Obliquus vertebrae. It came from a formation in Morocco, and is approximately 54 million years old, from the pliocene. Otodus is an extinct mackerel shark, related to the far larger O. Megalodon. The fossil is approximately 10.5 centimeters or 4.13 inches. I was wondering how large the shark would be relative to this vertebrae (assuming this was the largest vertebrae from the shark.)

crab with red flags?
Ezio Bonsignore posted a topic in Is It Real? How to Recognize Fossil Fabrications
Do you see any obvious red fkag with this one? It is described as Zanthopsis dufouri, 8×7×5 cm, Eocene (47.8-56 m/y), from the French region of Aude. It llooks very nice, but what both attracts and puzzles me it that it appears ti be "sitting" onto its matrix, like a jewel on a silk cushion. What do you thing? An excellent prep work, or...?

First tooth in question is from the Eocene Bashi Formation, Mississippi. Both Nebrius and Ginglymostoma are described in the formation. With this tooth, I think it’s Ginglymostoma but I figured it was better to post it and get some additional opinions. It’s around 5-6mm.

Is it real? Crocodile tooth, eocene, Morocco
Laleja posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone, I am very glad to have found this forum, as I have no knowledge at all about fossils. I got a fossil and wonder if it's real. The information I was given: It is meant to be a crocodile tooth from Morocco of the eocene. The person I got it from bought it 15 years ago from moroccan sellers in Germany. It was the first time they brought crocodile teeth with them (but other fossils before). Do you think it is real? To me it looks as if the crocodile went to the dentist's just a few weeks ago? If it's a real fossil I also would be v -
Hello everyone! I have been picking through microfossils from the Whiskey Bridge locality on the Brazos River in Texas. I used the hydrogen peroxide technique to separate the fossils from the glauconite matrix, and I have spent hours at the microscope, picking through the material to find the really tiny stuff. Here are a few batches that I've separated... My reason for posting this in the identification section, however, is that I have been running across a large number of echinoderm fragment

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)

In the last three and a half months I'd say I finally had the true college experience - always tired, hungry, and getting strangled by ochem 2 . But, my last final was yesterday, so time for a long overdue trip report. I'll go consecutively, with brief notes on the sights and interests encountered along the way, culminating with a prep update on the Plesiosaur I found over the summer with @Ptychodus04 and Joe. Unfortunately, the block containing the Coniasaur from the same trip hasn't been scanned yet. I'm also twiddling my thumbs for updates August/September:

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- 44 replies

Hey folks. Just got home from a rock and fossil show in Hamburg, where I bought 2 strange little teeth from southern France, Lutethian age, from the Aumelas region. They were labelled as crocodile teeth. But when I saw them I noticed they were very unlike usual croc teeth. The one in best condition has small fine (and quite sharp) serrations, the crown curves slightly to the distal side, and it is laterally compressed. Aumelas just so happens to be the same region, in which Iberosuchus remains have been found from Lutethian beds. The teeth of Ib

I know I dont post as often as I used to. Death of my middle son has a bit to do with that, but I'm starting to get back to life and not just go through the motions. After last xmas my oldest boy taught me how to Zoom and use an editing software program and I went head over heals with that and everything it entails. I've actually been enjoying prepping fossils again and making videos from that prep. Now, after some years, and with help from my youngest son I have finally cleaned up my garage and getting ready for some very large prep projects. and yes, all this prep will be turned into a

Found this around the top of bed D at barton on sea. I am in contact with a couple experts, however told like to see if anyone has any more information to offer to shed a bit more light. Crocodiles from this specific area are extremely rare but not unheard of, and so far the general consensus is that it could be crocodile predatory marks. The top and middle indent are both around 5-6mm in diameter, and the larger one is around 16-17mm.

Microfossil tooth & Other Questions about LaFarge Quarry in Harleyville, SC
dr00bie posted a topic in Fossil ID
I had the fortune of collecting at LaFarge quarry back over a decade ago. I didn't find a lot, but took home a 5 gallon bucket of material at the recommendation of another digger to go through for microfossils. Fast forward tp this weekend and I found the bucket of material. It has been drying for this long and is easy to break up. I am just getting started in the material and found a really neat tooth. At first it looked like a Great White tooth to me, but the root doesn't look right. I put under my microscope and found that the tooth appears more conical. The tooth is approximately 3mm in lo
