    Florida Mammal Teeth

    Below are two Pleistocene mammal teeth from "river gravels" in Florida. I have to further information on their age or locality, unfortunately. The left was merely identified as a "mammal tooth", and I strongly suspect it is from Trichechus manatus, but I have very little experience with mammal dentition and as such thought it would be best to check with someone with greater expertise in the field first. The right tooth was identified as a "peccary tooth", but given the fact that a number of tayassuids were present in Pleistocene Florida I wondered if the tooth could be identified to a genus, or better yet a species level. I will now take the liberty of "@ing in" a few people: @Harry Pristis and @Shellseeker Thanks in advance for any proposed ID's Othniel
  2. A short post today, just wanted to upload this interesting Rhizocorallium (?) I found on my most recent fossil hunting trip! It’s still the dead of winter here in Saskatoon, but we had a warm snap recently and I was able to hike out to a local glacial silt exposure and found it. Hoping to return to this site soon and hopefully find more!
  3. EDIT: Likely just a weird concretion or weathered chunk of rock. 😬Thanks all for the clarification. Hi all - while looking for Cretaceous fossils, I found some interesting chunks of what I thought might be bone of some kind amongst the piles of white limestone. When I cleaned them up at home, they started to look more and more like a very worn mammoth molar and some other fragments. Can anyone confirm the ID or offer any other info/ideas? Thanks!

    Haile Quarry, March 3rd

    I added a couple of threads on Activities connected with FPS field trip to Hallie Quarries in the vicinity of Newberry, Florida. I have some photos of the Quarry to provide a sense of what it was like and some additional finds. The Quarry I visited is just one of many at this location. and the one I was in... huge. A wall in the distance, heavy movers to stay far away from, a "tiny" FPS member searching the low wall ahead. I am walking around this mountain of rock on my left , searching for fossils that may have fallen down the cliff face. I am very careful the few times I attempt to climb the cliff face reaching for a fossil just a little too far away... There can be great rewards... Gorgeous, and and there are lots of potential shell, and echinoids in this semi hard rock, I have a rock hammer and trowel. Can I possible get this out in one piece.. I have already broken others or found that they were already broken before my arrival. So I decided not, and just walked on with a photo and a memory. As I continued around the mountain, I came to this site , took a step forward, and quickly stepped back . A sinkhole about 4 feet across, and with a single glance inside I saw it was at least 25 feet deep. This one is not particularly large. The Quarry has lost a number of large earth movers in sinkholes. This is where I recall signing the waiver stating that I am totally responsible for any of the various dumb things I might do while hunting for fossils and hold the Quarry owners blameless for any/all damages to my body. Roger Portell was our guide and Advisor and we moved a couple of times to locations that might provide different fossils. The last stop was supposed to contained marine (shark teeth) and mammal fossils. As we stepped out of our vehicles, Roger showed us another sinkhole, advised us to be careful , and described recoveries of mammal bones and teeth from this area decades past. I was fortunate to find one of those teeth, described in this TFF thread. https://www.thefossilforum.com/topic/139986-love-the-surprises/#comment-1479029 It was laying on the ground 5 feet to the left of this sinkhole. Sometimes I am just blessed in the right place at the right time. Here are some other finds of the day, with what ever I currently know about them... 1) M. americanum , a Sea Biscuit, approximately 4 inches in width, encased in matrix. 2) What I refer to as Jingle shells, and a small Echinoid...On the Echinoid, I have to wash, brush , scrap off some of that concrete like matrix to figure out what it is.... 3) A couple of Oysters... there few shells free floating from the concrete like matrix like these. 4) More shells, this time in Matrix 5) Did I mention Endocasts ? All over the place.... Sometimes hard to differentiate from shells. 5a) This one reminds me of a cowrie.... but not like any modern or even fossil ones that I have seen... I had previously found exactly like this one in a bone valley creek.. Would like to Identify.. Hope you enjoyed the trip. Comments always appreciated.

    Concretion with Fossil inside

    I found this concretion with something inside, looks like half of a nodule with something bone alike. Found it while sifting for Miocene shark teeth in a clay quarry in the Antwerp region in Belgium. I think the gravel i'm sifting is Pleistocene with reworked Miocene as i've found pieces of Mammoth bark in it as well. This piece leaves me clueless tho.. The concretion measures 9cm x 5cm sorry about the poor quality pics, that's the best i can get out of my smartphone... Thx!
  6. Recently found this quite large and heavy (piece of) bone by the Schelde river shores in Antwerp, Belgium. Most pieces that wash up here are Mio/Pliocene but actually most Neogene layers are represented in the area as well as Pleistocene and more recent. I'm thinking whale because of the size, but honestly i don't have a clue. Measurements are 22cm x 10cm x 5cm thanks in advance! Dries

    Pleistocene Rock Marine Imprint

    On a recent visit to Key West, Florida I found this imprint in a rock along the shore. This was a piece of rip rap, so its original location is unknown but I believe most of the fill and rubble in the area was sourced fairly locally (South Florida). The bedrock at this location is the Pleistocene aged Miami Limestone, which is from the Wisconsinan to Sangamonian stages (<700,000 years) but even in all of southernmost Florida (say Miami and south) the oldest you get is Pliocene. So, while I don't know the exact age, I'm pretty confidant it is fairly young. The imprint is about 5cm wide by 9 cm long. Hard to tell in the picture perhaps, but it is probably 3-4 cm deep. In the picture on the left, you see the whole rock, including the other bivalve casts etc in there. Looks pretty typical for what I saw in the limestones of that area. The picture on the right is the impression enlarged. I did not bring it home with me, so this is the best I can do with pictures. My first impression was it looked like the impression of an ammonite septal wall, but of course it is much to young for that. Only other thing I can think of is the impression of the top of some type of coral, maybe a brain coral, but I'm struggling to visualize it as it looks too symmetrical for that. The detail is pretty neat. Anyone recognize this? @digit @hemipristis @Harry Pristis

    Equus Upper Jaw Teeth?

    This is an Iowa sand bar find. The (large) molars seem to be more rectangular than other more square equus teeth images I have seen. Also, there are only four teeth with one not yet emerged. I believe this indicates that this jaw is from a young animal with only having the deciduous "milk" teeth. Any help zeroing in on a specific species would be appreciated!

    Raptor Claw

    Peace River find. I think it is a Raptor claw. Would appreciate any other possibilities. Some questions: Can we tell left or right foot ? Which digit (Obviously not hooked)? What Raptor? and finally.. Is it modern? @Auspex
  10. Hi Everyone, I am completely new to the forum but have loved fossils since I was a kid holidaying on the Jurassic Coast in the UK. I was searching for potential fossil sites in the Netherlands and went to Zandmotor (Den Haag, Netherlands) hoping to discover a complete Mammouth Skull. Sadly this hasn't happened yet, but I found numerous interesting finds (which I photographed below). My girlfriend and I have managed to identify most of them however I am having trouble identifying the second picture of the (brown pointed pieces). I think they could be fossilised wood (they look wooden to me but then part of me thinks they could be bone - ribs perhaps). Of course, they could just be nothing at all. My Girlfriend's 9-year-old daughter now has to know what they are, so I thought I would ask some experts. I would love any input on this as this is not something I have encountered before. Any help would be gratefully received. Many thanks in advance Mickey
  11. Last month I posted an Id request for 3 molars, and two were identified as Peccary. Just to be clear, I personally did not find them, as I was requesting an id on behalf of others. The third tooth was left unidentified, and I was recommended by Shellseeker to contact a museum for help. If you would like to read the original post, and view photos, here it is: I eventually contacted the Denver Museum of Nature and Science, and David Krause of their Paleontology department sent me this: ''Hi 'Jaybot' –– No worries. Thanks for getting back to me and for confirmation about the scale bar. The fact that your scale bar was in centimeters helps to confirm Kristen's (cc'd here) tentative identification that your tooth is that of a Plio-Pleistocene mega-marmot, the genus name of which is Paenemarmota. The largest species is Paenamarmota barbouri (close to modern beaver size) and your specimen seems to be in that approximate size range, although precise measurement is warranted. After Kristen's tentative ID, I reached out to one of our Research Associates here, Greg McDonald, who is another expert on Plio-Pleistocene mammals, who, in fact, has recently published on Paenemarmota (see attached file). He tentatively confirmed Kristen's identification and further identified it as a right lower third molar.'' Here is the paper he attached in the email: McDonald et al. - Paenemarmota from NM - 2022.pdf This is very interesting to me, and I figure that y'all might enjoy this as well. I would never have guessed mega-marmot I'll tag everyone in the original post so they can find this: @jpc@Danielb@Balance@Shellseeker@dries85@CDiggs@Harry Pristis Have a great day!

    Pleistocene mammal ulna

    This bone has been tucked away for years. Just waiting for a rainy day to seek out an id. All I know is that it was found in SE Texas Pleistocene river gravel. Looks like an ulna. I can safely rule out bison and horse. Don’t think it’s deer. I’m kinda leaning toward carnivore, but really not sure.

    Dire Wolf or Gray Wolf Vertebrae?

    Hello Folks! I have an Iowa river find. I am fairly certain this is a wolf vertebrae fossil. This was found in an area rich in Pleistocene Era fossils. What I do not know is how to distinguish between a Gray Wolf and Dire Wolf vertebrae. The Dire Wolf vertebrae should be a bit larger than a Gray Wolf vertebrae but I cannot find a source for actual dimensions. Thank for looking.
  14. I found this on the beach in Georgetown,South Carolina, USA. The beach is in the Waccamaw Geological formation & same area l found other Pleistocene megafauna fossils ( mammoth, bison & horse ). I believe it is a reptile skull with its lower jaw missing. It has symmetrical nostrils & 2 pinholes (photo 2) that pass thru and exit 50mm back itself. There is a raised ridge above the “nostrils” (photo 3) & it appears to have two broken eye sockets on each side (photo 4). Toward the front of the roof of its mouth it looks like 5 to 6 evenly spaced tooth sockets (photo 5). ( I have compared it to turtle skulls online but l can’t find anything similar) I will post more photos or measurements if needed) any input or ideas is welcome & greatly appreciated.

    SE Texas - Small tooth

    Size is 42 mm in length 20mm across chewing surface I found this little tooth today. Nice colors on it. It's not horse, bison, or cow. I think it's an artiodactyl.... camelid/llama? Pleistocene material found here.
  16. Started going through some of my older finds and thought I’d try to identify some of them. These are all found in Gainesville, Florida creeks. First one is just a chunk of bone, not sure if it’s even identifiable. My guess is part of a scapula because it’s somewhat flat and curved. Second is a small bone, maybe a carpal of some sort? And third, I’m thinking is a partial alligator tooth. I can see a small bit of enamel left on it, but the enamel seems to have some ridges on it which is confusing.

    Mammal teeth ID

    Hey, i got some mammal teeth ID vibe going thx to @citronkitten's post. I'm kinda in the dark about these two teeth. As they wash up on the Schelde river shores in Antwerp i'm not sure on their age tho. Both look like front teeth to me. 1. 2,9cm x 1,3cm x 0,8cm 2. 2,6cm x 0,8cm x 0,6cm Thx in advance!
  18. I found this on the beach in Georgetown,South Carolina, USA. The beach is in the Waccamaw Geological formation & same area l found other Pleistocene megafauna fossils ( mammoth, bison & horse ). This fossil has a toad skin like appearance with row of nodules dividing a semi flat surface & a 45degree angled rough surface. Any help with identifying it is welcome & appreciated.
  19. The following were found in Sarasota County, Florida (USA) on public land eroding out of berms. They appear to be plio/pleistocene. Using the forum and several books, I've ID'd the best that I can. I'm looking to confirm the ID's. Any and all assistance is appreciated. 1. Turritella acropora 2. Arca wagneriana 3. Eucrassatella speciosa 4. Terebra dislocata 5. Carditamera floridana or arata 6. Terebra aclinica 7. Cantharus multagulus 8. Anadara brasiliana 9. Strombus floridanus 10. Unknown Strombus
  20. I found this on the beach in Georgetown,South Carolina, USA. The beach is in the Waccamaw Geological formation & same area l found other Pleistocene megafauna ( mammoth & horse ). This tooth has smooth waved enamel sides, rough jagged crown & root with 4 holes. Any help with identifying it is welcome & appreciated.

    Mammal Bone on UK beach

    Hi Everyone, I went fossil hunting last weekend on the Norfolk coast, UK. A long walk up and down the beach of Happisburgh. Well known for its Ice Age mammal finds. I found a few different pieces, but this one in particular caught my eye. It's been rolled around in the surf somewhat, but I was hoping someone might be able to ID this for me? Because it does retain some shape still, it kind of looked like the end of a femur or tibia? But it does also resemble an ankle bone from a large animal, possibly Mammoth, Rhino or Bison? What do we think? Thanks in Advance, Jim.
  22. Found this tooth on the beach last week. I have found Pleistocene horse, bison & mammoth teeth on the same beach. Any info would be greatly appreciated Georgetown, South Carolina, USA.
  23. I found this grapefruit sized (possibly tooth) getting washed up in the surf in Georgetown, South Carolina, USA. I have found what I believe to be Pleistocene Horse & Bison teeth on the same beach. Any help identifying it would be greatly appreciated.
  24. Hello, All 🙂 Found this sitting on the riverbed while crossing a shallow section a month ago or so. Same spot I found a bovid cervical vert trip Before. Tossed it in the boat as a modern cow thoracic to identify “which one”. Saved it for a day when the temps cold and the water is up. That’s today, only problem is I can’t find a vertebra with a fork in it to save my life. Cow, horse, camel , oxen… no forked thoracic. Can bovids of different breeds have different vertebrae characteristics? Is this not a thoracic vert? Where too next?? its 7.5” long and 3” wide with the broken piece added back into the measurement. That’s 187mm ish long… Peace River , Florida modern thru Miocene Thanks for any insight or suggestions. Appreciate the feedback Jp

    Fossil teeth ID

    I am not a tooth person, hope someone can help identify which animals these are from. I suspect most are Bison, with some elk mixed in as well. All were found along a river eroding through glacial Lake Agassiz beach ridge. Disregard the two bison petrous bones, I am going to send those in to get dated. Thank you.
