Hi Everyone! This came from the Peace River of Florida, I'm torn between Casteroides and Neochoerus. Measurements: 18 mm tall 13 mm wide 10 mm thick thoughts?
-
Hi all, any ideas on this? Found on the south american atlantic coast line. Looks like some kind of lower maxilar from a rabbit-like animal from the pleistocene. Any additional info is greatly appreciated, Thanks a lot. James

I found this large bone at the Kansas river today. I believe it's permineralized phalanx and it is about 4 inches long. If anyone can help me out I'd be very appreciative. If you need more photos let me know. Thanks in advance (Apologies for not using centimeters, I couldn't find my tape measure so I used a yard stick. )

Hey Gang, Here's another I could use some help with. I had it in the turtle/tortoise remains pile to be researched as it was found with some turtle remains but looking at it now I think it actually is mammal. Gonna guess maybe a scapula and I was wondering if it might be from something like a dolphin as I have a similar but much larger one? Looks like the larger flat fan shaped area has all been eroded/broken off. Plio/Pleistocene? Florida. Approximately 50mm X 50mm at its widest--tough to measure due to its odd shape/3dimensions. Any help in validating the bone type and/or the critter is much appreciated! Thanks! Regards, Chris

Mammoths and other large animals survived in the north much longer than previously believed. New DNA research indicates that the climate, not humans, led to the demise of these large creatures, Norway Science, January, 2022 The open access paper is: Wang, Y., Pedersen, M.W., Alsos, I.G., De Sanctis, B., Racimo, F., Prohaska, A., Coissac, E., Owens, H.L., Merkel, M.K.F., Fernandez-Guerra, A. and Rouillard, A.,2021. Late Quaternary dynamics of Arctic biota from ancient environmental genomics. Nature, 600(7887), pp.86-92. It concludes that mammoths survived in continental northeast Siberia until 7,300 BP; North America until 8,600 BP; and the Taimyr Peninsula as late as 3,900 BP. Yours, Paul H.

Hi Folks, I've made two trips to the river in the last week and most of what I have found was the usual stuff. This mammal tooth is eluding me when it comes to ID. It's a little banged up, but I think enough of the crown is intact to facilitate an ID, but I can't find anything that looks close. Anyone know what critter this is? It does appear to be fossil and not recent. Thanks! MikeG PS - a proper trip report and more photos coming later.

Hey Gang, I saw Jack's recent thread about camelid bones and remembered I still had this little piece shelved. I've actually got 2 fragments that appear to me to be limb bone ends that have what I think are 3 articulating surfaces but I'm only intrigued by the 1st specimen at the moment. Its about 43mm long, 28.2mm wide and approximately 19.3 mm thick at its widest point on the end. The usual Florida Plio-Pleistocene? in probable age.. I've gone thru a number of joint/skeletal images and am wondering how many different kinds of bones can have 3 articulating surfaces? One surface on the end and the two smaller areas on the sides. Is there any easy answer to that? Carpals, Metacarpals, Tarsals or Metatarsals? Any help/insight/or ID is appreciated! Thanks Regards, Chris

Hi guys I have this pleistocene vertebra from Peterborough, uk and I was wondering if anyone could help to identify it, I was thinking bovid of some kind?

I recently acquired this rhino jaw advertised as a woolly rhino, yet ad said it was found in southeast asia, which would be inconsistent. Seller then said it might come from the Russian-Mongolian border. Can anyone tell the difference anatomically between a woolly rhino jaw and its southeastern asian contemporaries'? Age range stated as 20,000 to 40,000 years ago.

I went fossil hunting in the Peace River, western Florida a few days ago and found many fossils, mostly sharks teeth. Several I am not able to identify. If these pictures are not adequate I can add more. Wasn't sure if the last one was a fossil, but it's very dense like a dugong rib so I kept it. The first piece has three pictures, the second piece has three, the third has three and the fourth has two.

Found what looks to be a partial jaw with root fragments in Southeast Texas the other day. Looks like it would have had two smaller incisors in front with two much bigger teeth to the sides. Then a smaller peg tooth on each side. Boxes on the green mat are square inches. I've looked through all my books and at some different jaws online, but I can't find anything that seems to match the number of incisors and and size difference. Any ideas would be great.

This is probably a Mike question @MikeR but does anyone know which Pecten this is? Argopecten? Chesapecten? Just getting around to asking and trying to hopefully understand what the age is. Thinking Pliocene but wondering, if yes---upper/lower? Both valves attached. 19? ribs. Thanks! Regards, Chris

Hi all, A friend of mine found 3 of mammal bones on the beach washed ashore after the storm from last weeks - but I'm not too good in these. Might anyone help me out to ID this - if ever possible? Big thanks!
-
Really stumped with this one, but it has a pretty distinctive shape, so I'm hoping someone with more experience can pretty easily tell what it is. Found it in southeast Texas. --Brandy

Life is good. I go out tomorrow to the Peace River. I was also there Monday.. There were a few nice finds. I found 1/2 of a carnassial, maybe dire wolf. Seems like I found a mostly whole one in early February. Here is an interesting toe bone. Back 10 years ago , I found a Toe bone, identified as Jaguar 39 mm Medial phalanx by TFF experts. Note the recess to accomodate a retractable claw in the left of the 1st photo.. Then Monday, another toe bone, only 25.5 mm in the sieve. BIG smile. I think once again it is a Medial phalanx. So, is it a Feline Medial Plhalanx (from a smaller cat than Jaguar) OR Maybe a Medial Phalanx from Holmesina floridanus, another candidate from the Florida Pleistocene. Photos below from online. and most of all, what do you see in the photos to choose one over the other... Thanks for all comments and suggestions. Jack

I think I know what this is, but will hold off until other input is given..... found on the Brazos River in Texas, Pleistocene @Harry Pristis @Lorne Ledger @fossilus

Texas has a lot of Pleistocene bones present in the southeast portion of the state north through Dallas. From reading, they are found in a limestone gravel bed layer. Do these bones tend to be subfossils or bone that has undergone extensive mineralization? I’m curious, trying to find online if anyone has managed to extract ancient DNA from Texas bones. Much more likely from subfossils. Also, would anyone have a picture of what the Pleistocene limestone gravel bed layer in Texas looks like? Thanks!

Late Pleistocene Tahoka formation in west Texas?
fossil_lover_2277 posted a topic in Questions & Answers
I’m familiar with the Pleistocene Beaumont formation and some of the Pleistocene deposits around the Dallas area, but what about the Tahoka formation (I believe it’s near the Texas/New Mexico border)? This formation is late Pleistocene (~36,000 years) correct? Does anyone on here have experience searching for vertebrate fossils from this formation? What are the sediments like? How fossiliferous is it? -
Found what seems like a partial skull and possibly an ear bone. Southeast Texas. Never found anything like this before, but the darker smaller segment reminded me of ear bone threads I have seen. The size and general shape of the darker 'ear bone' sent me in the mammoth direction, but I'm not confident in it.
-
I found this in Southeast Texas. It seemed to resemble a big cat metapodial that @garyc found and posted on a past thread, but it has differences, so I could be barking up the wrong tree. Is it a metapodial or something else entirely? Any suggestions? Thanks.

Hi All, I found this while diving the Cooper River in South Carolina. It's most likely Pleistocene. Passes the burn test with no odor. Hopefully the morphology is unique enough that someone will recognize it. The big end has an articulation joint. Is this possibly a claw core? Or is it fish? (The bone structure seems fish-like to me)

Is this a modern pig tooth or a peccary tooth? I found it in Montgomery, Alabama, where Pleistocene fossils have been found.
-
Hi everyone! So, yeah. How does one tell the difference? It measures 2.28 inches straight line, .51 inches wide.

The river has been receding daily, and I found this sacrum two days ago laying in sandy gravel that had just been exposed. Mostly Pleistocene fossils here. Due to its size, I thought it may be from one of the larger herbivore mammals. But due to wear, it's a little hard for me to tell how tapered or straight the original structure was, which seems pretty diagnostic in differentiating between the species. Several examples I've seen look similar, but I'm having a hard time finding any with sizes listed, so I'm a little lost. Can anyone shed some more light on this? Thank you! --Brandy
