My last time out hunting was 2 weeks ago, just before the deluge. Found some nice items including 2 small upper horse teeth, and then stopped at a hunting friend's home, where he sold me a number of fossils, including 4 additional small horse upper molars. 1st tooth I believe to be Merychippus from the Miocene of Florida. I found/donated one of these to Richard Hulbert, Florida Museum of Natural History 18 months ago. It looks like some HSBs --- Hunter_Schreger Bands are more easily discernible than on Equus teeth. Tooth #2.... One of my finds... a Nannippus I think... there were 4-5 species in Florida Tooth #3 Another Nannippus.... little bit larger... Look at that isolated circle on the left ... I wonder if that is diagnostic. Tooth # 4 is once again larger... might be Nannippus, but I am less sure.... Tooth #5 is not Nannippus,, which leaves lots of other Genus and lastly an interesting , different and slightly damaged tooth... Definitely need a thread to follow on this one... I have sent the Photos to Richard Hulbert, but with his semi_retirement, I would like to start depending on TFF expertise.... Usual suspects, @Harry Pristis, @fossillarry @siteseer @darrow Thanks for any and all insights and threads to follow... as Always I am after Genus, Species, Jaw position. All this starts with Genus.

Hi all! It has been a long time since i have made a post here, as i have not been out and about fossil hunting too much. Any ideas on this Fossil bone? Not looking for a specific species, genus would be great though. Miocene to early pliocene. Thanks

These two bones come from North Carolina, and the site they come from produces mostly Cretaceous Black Creek group material, but also some marine Pliocene and terrestrial Pleistocene material. Any help would be appreciated! The first is clearly a limb bone shaft, femur, tibia, something like that. Not sure if it's crocodilian, turtle, dinosaur, or terrestrial mammal though (I'm leaning towards terrestrial mammal). The second bone I'm thinking might be some type of hip bone, I was thinking possibly the ischium of some large croc, but I'm not sure. Could very easily be some random cetacean skull fragment. Edit: I think the second bone may be a crocodile coracoid. That large hole may be the coracoid foramen. Let me know what you think. Bone 1: Bone 2:

I’d like to see the Pliocene fossils from California that people have I’ll start off with some fossils I collected from the Purisima formation at Capitola Beach A vertebra with a shell on the back A heavily eroded whale vertebra with some associated (rib?) bones Some cool clam shells Edited to add: Here’s a clam shell I dug up from the Pinole Tuff formation when I was 7. It was the first fossil I ever found

Hi every! I got this one from an old Chinese medicine store, the owner said they came from Gansu province, China. After I prepared, it turn to be a mammal vertebrae bone but I don’t know exactly the species or at least the family or order. Could anyone help me to have a look about this one? Thank you guys!

Stopped in Chippokes State Park on my way to Norfolk VA. It is a historical plantation on the banks of the James River. Fossil collecting is legal and encouraged , however sections of the beach are divided by rip-rap, and other sections are prohibited because of cliff falls. I collected on the beach, and in walking in the near woods ( to avoid climbing over the rip-rap) came upon a small recent hill slide. The beach picture is from the Chippokes web site taken by Sean Hazzarts, the shell hash photo shows typical beach accumulation, and the green photo shows my woody hill. The other randomized pictures are my finds for the day. A ecphora, several Chesapectin jeffersonia, a drum fish mouth plate (I thought at first that it was a croc scute until I turned it over) . It is another place where I didn't find a megalodon though they are reported here. It is a nice place to visit in the summer, beach, water, fossils and family.

Out hunting yesterday... went by myself. Not always a wise choice. But I was a Boy Scout some eons ago. Always be prepared. Heavy rains in the area increased the flow rate. Going a little faster than I should have on the way back, caught a log 6 inches below the surface, flipped the kayak as neat as you please. Having experienced this before, everything was in the hatches or lashed down, paddle leashed, no hat ,no sunglasses. Had my sit_in kayak, so as I resurfaced , grabbed the side of the cockpit and my weight pulled it over upright... along with 10 or 15 gallons of water. The water was well over my head, so I grabbed the kayak leash and dog paddled toward the bank while the current moved me and kayak rapidly downstream. Took me 10 minutes to empty the cockpit with a siphon hose and small bucket, which I always keep in the forward hatch for exactly this situation. On top of that excitement, I had a really good hunting. Lots of fossils, nothing spectacular. So, I pick and choose what to ID first... I found what I believe to be 2 Astragali.... First up, one that I have found many times before , and using @Harry Pristis gallery and pictures, identify as a camelid. It is too small for Bison and not cow due to position of the medial tubercle.. If anyone has knowledge, I would like to know if this is Palaeolama mirifica or Hemiauchenia. or Next... and even though it is badly broken, I am excited by the potential.... I have seen this before but NOT at this location. To give you a sense of where I am going... Capybara has a somewhat similar Astragulas, and the closest comparison in my collection is a (much larger) Teleoceras Astragalus I found in the Peace River in 2014 (photo below). The more realistic part of me is thinking a modern wild pig which can get up to 400 pounds wandered into my hunting area.

“Parrotia” pristina (Ettingshausen 1851) Stur 1867 with feeding traces.
oilshale posted a fossil in Plants
Taxonomy from GBIF.org. There is a complex literature about this polymorphic species. Similar leaf shapes possess the recent genera Hamamelis L., Fothergilla L., and Parrotia C.A. Meyer, therefore the term "Parrotia" pristina (Ettingshausen) Stur is used. Quote from B. Adroit 2020, p. 4 regarding the feeding traces: ”Currently, the main reference to identify and classify the plant–insect interactions in the fossil record is the ‘Guide to Insect (and Other) Damage Types on Compressed Plant Fossils’. This guide subdivides herbivory traces on leaves into seven functional feeding groups (FFGs): hole feeding, margin feeding, skeletonization, surface feeding, mining, piercing and sucking and galling.” This type of feeding trace was assigned to the damage type DT297. Identified by Dr. B. Androit, Swedish Museum of Natural History. References: Stur, D. (1867).

Hi TFF, I've posted about this Pliocene baleen whale jaw section from Florida before, and its the gift that keeps on giving! Within the fossil there are 2 significant crystalized structures which I would love further clarity on. Are they the remanence of soft bodied organisms burrowing in the bone? Or are these structures mineral deposits similar to those found in shelled cephalopod fossils when water gets into the specimen? Or something completely different? The first specimen is 1.7/2cm in length. I would love to know your thoughts

Went out to Green Mill run not too long ago and found some fossils that I simply couldn't identify. I have my suspicions of what they could be, but would rather get some expertise identification. Any help is appreciated!

Taxonomy from GBIF.org. The recent Fundulus zebrinus was originally native to the following areas: Mississippi River and Gulf Coast watersheds from northern Missouri to central Wyoming and south to the Colorado River, Brazos River, Galveston Bay, and Rio Grande (mainly Pecos River) watersheds in Texas. Mostly on Great Plains. References: Koster W. J. (1969). Fishes of the Rita Blanca Lake deposits, pp. 135-139, pl. 23. In: Paleoecology of an early Pleistocene lake on the high plains of Texas. R. Y.

What is the geological age of the site where the megalodon was found in Indonesia?
Jerrychang posted a topic in General Fossil Discussion
Recently I bought some fossilized shark teeth from sukabumi, indonesia. There are plenty of bulls, dusky, lemons, big hemis and tigers and a lot of giant megalodon, but why are there so few great white shark teeth, and why hastalis almost never seen? Is it because hastalis are extinct at that time? And is it because the great white shark failed to compete with the megalodon in that place?
