  1. From the album fish

    Thanks Marguy!
  2. Echinoid "cores"

    Just thought I would post some pictures of these (Ryncholampas gouldii) echinoids that I cut/ground/sanded/polished into cross-sections to show the variety of the fossilization processes. The white one was found on the bank of the River in a limestone matrix. The other five were found in a different river bottom, all in close proximity to each other. Even though they all were in the same type of dark sediment/rock, they all have different combinations of materials/layers/etc. were all extremely dense and hard to cut/grind - like a granite/marble material. For anyone not familiar, one of the pictures shows the profile of a full intact specimen (a "before" picture). Another picture shows an "after" profile picture, showing how these were taken down to approximately 1/4 inch thickness. For what it's worth, the darker the material, the harder/more dense it is.
  3. Last weekend I went for a very short trip to the Carpathian Mountains, to find some Oligocene stuff. Every year it becomes more and more difficult to find nice complete specimens, because the locations are (unfortunately ) quite easily accessible and therefore there are plenty of fossil hunters (especially now during holidays). The first location is situated close to the place we commonly refer to as the Polish Texas :), called Bóbrka - it is the world's oldest (and still operating) oil mine. https://bobrka.pl/en/about-the-museum/ Nowadays it operates also as a museum, where you can see old drilling equipment and see the well up close The location is called Rogi:
  4. Unidentified Bones from White River Formation

    Hey everyone - I dug up two bones and put them together but can’t figure out what the bones are and what species they are from. I found it in the White River Formation and the first bone (first picture) is about 4 inches long, while the second bone (second picture) is about 6.5 inches long. I found the bones right next to each other. Does anyone have any idea what they are or if they possibly connect or are part of the same bone?
  5. Unidentified Oligocene... Something

    I found this in a Benton county crumbly fossil rich road cut that I'm fairly sure is Oligocene based upon the other fossils present. Other fossils are all aquatic and includes a lot of clams (Pitar) and a few snails (Siphonalia, Neverita) The fossil in question appears to have been a hollow tube that's been broken open, but I'm unsure if that's actually the case or if the end is simply folded in a way to give that illusion. I initially called it a bone in my excitement, but now I could see it as being plant matter of some kind. This is kind of a shot in the dark, as I'm unsure if it could even be identified based on such a vague fossil. Edit: It's about 2 inches or 5-6 centimeters
  6. Unknown Maxilla from Oligocene

    Hey everyone, I was digging in the White River Formation when I found this amazing maxilla of some creature. Through some questioning and conversations with various paleontologists, many people have different opinions of what this is. The responses I’ve had are all different, being Oreodont, Dire Wolf, or a species from the family of Brontotheriidae. The w shaped teeth might suggest Brontotheriidae... What are your guy’s opinions? The maxilla is about 6 inches long.
  7. Hi all, trying to get some id help with some teeth from the Brule Formation, Nebraska. Most i think are oreodont, mesohippus and similar. Unfortunately dentition is not my forte, so any assistance would be appreciated. Tried to take photos from three different angles to help. Set 1, 2-specimens Set 2, 3-specimens (lower 2 mesohippus maybe) Set 3, 2-specimens Set 4, 1-specimen Set 5, 1-specimen (mesohippus maybe?) Thanks for everyone's help again. MUCH appreciated, Paul
  8. White River fm. Mammal Teeth

    Hey everyone, I found these teeth in the White River fm of eastern Wyoming last summer and wanted to see what people on the forum thought they were. 1st is what I believe to be an oreodont tooth (possibly Merycoidodon). It's .8 cm wide and 1.5 cm from root to crown. 2nd I believe may be a Poebrotherium tooth but I'm unsure. It's about .5 cm wide and .9 cm long. 3rd may be from a Leptomeryx but I'm not sure. It's about .4 cm wide and .9 cm long.
  9. Nebraska

  10. From Badlands National Park

    Any idea what this might be? Or even what body part (skull?) We found this hiking in Badlands National Park in western South Dakota. We were hiking through bluffs made of Oligocene sediments that were rich in mammal fossils. Unfortunately no scale in the photo, but it was about 12 cm long and 10 cm wide.
  11. Fossil I.D

    Hello fellow TFF Members Does anyone have any idea what this might be? Found it, and another one very similar, in the Creede Formation of Creede, Colorado. Sorry that I did not put in a scale; it is approx. 3" in diameter. The center circle has radiating lines. From that circle there are several concentric rings. From what I have read, the site was a salty lake formed in the Creede Caldera. Most of the fossils are plants and the sediment is fine grained volcanic ash. Almost looks like a jellyfish to me. Any I.D. will be much appreciated. I am stumped. Thanks, ODK
  12. Oligocene

    Due to the smaller cusp, these would be Carcharocles Angustidens??
  13. Carcharocles

    This group of teeth should be from the Eocene period? Carcharocles Auriculatus I am guessing due to the size of the cusp?? Teeth are 1.4" and found in the Chandler bridge formation.
  14. Dermal denticles

    Originally from the Midwest, I've been hunting for fossils for about 50 years and found about two "fossilized sea shells". And this was not from a lack of trying! I moved to Summerville, SC about three years ago for a job that included lots of travel. Now that travel is finished and meeting new friends in the area, I have connected with some kids that stumbled onto something that I think is big! Had I grown up in Summerville, I probably would have change my career to paleontology instead of Electrical Engineering. I am amazed at the finds here in my home town. I have taken my wife and kids including their friends to a spot that allows them to find Shark teeth (at a minimum) within 2 minutes of arriving to an area. My dilemma, I would like to know what these type of "dermal denticles" are. For every 20 shark teeth I find, I find one of these. Please refer to the attached pics. Thanks Matt
  15. M&M Ranch in Nebraska

    My younger son Mel just led his first fossil trip of the year on our Oligocene M&M Ranch in Nebraska last week. My sons, Mel and Marco Jr., are starting to get back from their prepper some of the fossils that they found on our ranch in 2018. Not all fossils go to the prepper. Mel preps some of the specimens himself. Below is a picture of the specimens Mel found in 2018 that he will prep. Here are a few pictures of 2018 specimens just back from the prepper. Mel found another saber cat in 2018 that is in prep. Below are a saber cat skull found by Mel and saber cat skeleton found by Marco Jr. (the skeleton was still in prep in this picture and I can't find the finished picture right now) in previous years on the ranch. They have found seven or eight so far on the ranch. I'll probably be going out to the ranch a couple of times this year. However, I spend most of my time at the ranch taking matrix that contains micro squamate, bird, amphibian, and mammal specimens. I'm currently working with seven researchers on this micro material.

  16. My Giant Alopiid Collection

    Hello Everyone, I’m rather fond of Giant Alopiids, and I have taken to collecting them. I find it strange that such a wonderful, yet mysterious creature remains relatively unknown and scantly studied. I may have space in my high school schedule for an independent study senior year, and I’ve considered using it to make a poster or paper on their morphology, taxonomy, phylogeny and such for The Rostrum or something. However, I’ve heard tell that there is already a comprehensive paper on giant alopiids in the works. We’ll see if there will be anything left for me to discuss. Anyway, collecting them is a slow process as they are quite rare and I am quite cheap (I have yet to find one myself). I thought I’d make a thread to show off what I have thus far and to keep them cataloged for myself. Hopefully this page will grow as time goes on Dashes are around 1 inch apart. South Carolina Alopias grandis
  17. Bone ID request

    Good afternoon, I have now found a total of four bones with this same shape. Found in Jacksonville, NC at Onslow Beach. I posted one over a year ago that was too worn to identify. Since then I have found these three with two in much better shape. Any idea what this bone has come from in relation to location on body and hopefully what animal? Thank you
  18. Oreodont in situ - Nebraska Oligocene

  19. Are there any Seattle-area folks on here who have tried hunting for beach fossils around Alki Point? You can see the outcrop pretty well on satellite images and it's on the geological maps. This Blakeley formation is pretty crumbly, though, so I'm not sure whether any meaningful fossils would survive being washed out in the surf. Guess there's only one way to find out! Since we're coming up on the new moon, the low tides are nicely timed for a long lunch break, so I'll plan to check this out some time in the next few days and report back.
  20. Document Requests : Ediscetus

    Hi, I forgot to mention anyone has a copy of the following paper: Albright, L. B., III, A. E. Sanders, and J. H. Geisler. 2018. An unexpectedly derived odontocete from the Ashley Formation (upper Rupelian) of South Carolina, U.S.A. Journal of Vertebrate Paleontology. DOI: 10.1080/02724634.2018.1482555. Also, I wanted to see if anyone has scanned a copy of " Neogene Cetacea of the Lee Creek Phosphate Mine, North Carolina", because the publication in which this section is included carries a hefty price tag.
  21. Possible tooth-unknown species

    Good afternoon, on a recent trip to Onslow Beach located in Jacksonville, NC I found several interesting items. I will list each separately. I have researched each item and will provide my thoughts on identification. Please feel free to correct me and or provide greater guidance as I am a true beginner. My third item- I believe this item is a small tooth. The shape appears correct however, I have not seen one that looks like this specimen coming from this location. The specimen is very shiny- even when dry as seen in the attached photos. Any help you can provide is greatly appreciated.
  22. Possible Turtle Humerus Bone

    Good afternoon, on a recent trip to Onslow Beach located in Jacksonville, NC I found several interesting items. I will list each separately. I have researched each item and will provide my thoughts on identification. Please feel free to correct me and or provide greater guidance as I am a true beginner. My second item- I believe this item is a turtle humerus bone. The size, shape and slight twist appear to be correct however, I am not very confident in my ID do the species and bone type. Any help you can provide is greatly appreciated.
  23. Possible Mammoth Tooth Fragment

    Good afternoon, on a recent trip to Onslow Beach located in Jacksonville, NC I found several interesting items. I will list each separately. I have researched each item and will provide my thoughts on identification. Please feel free to correct me and or provide greater guidance as I am a true beginner. My first item- I believe this item is a small fragment of mammoth tooth. The ridging appears correct however the fragment I’d very thin/small so not very confident in my ID. Any help you can provide is greatly appreciated.
  24. I finally got around to working on some Oreodont stuff. Last year I stopped by a friends house and bought a bunch of White River material. (my friend is going to stop by this May and bring me a bunch more). I did some work on some Oreodont stuff 20 some years ago and figured it would be fun to work on some more. I will call this skull #1. I realized at once that some of the skull was missing. Not good. I had already opened up this one and took off a bunch of loose rock and then decided to take a photo. You can see the earthquake crack in the rock and this thing was litterally falling apart all over the place. In this picture ive removed all the materail on the right of the crack including upper and lower jaw pieces. I was quite nervous but it was also fun and exciting. At this point ive use up almost an intire 2 oz bottle of super glue to hold the top part of this all together and when I turned it over, very carefully, lots of rock just came off with no prodding or nothing. The good thing was that the upper part held together and you can easily see the lower part of the lower jaws. At this point it was time for a wiskey. Here I glued back on the missing lower teeth. This thing was so fractured and falling apart the nothing really fit like it was supposed to but did the best that i could. Those extra two pieces on the left hand side also need to be glued back together and then both glued back onto the skull. Ok, bottom pieces glued back on and now set aside to cure. Tomorrow is gunna be a fun day. RB
