  1. Calvert Cliffs Vert-Terrestrial Mammal?

    Hi all, Something different for today. I discovered this vertebra in the surf at Matoaka Cabins roughly 2 years ago. For those of you that don’t know, the rocks here are Miocene in age and preserve a nearshore marine environment. Cetacean remains are common, but other mammals (esp terrestrial) are not. Originally I thought it was a turtle vert, but now I’ve realized that it’s mammalian and possibly terrestrial in origin. It passed the burn test, by the way. My thought is that it is from a small mammal’s tail, as it closely resembles other mammalian caudal vertebrae. I’ve included a diagram of the vertebrae of Phenacodus, which show marked similarity. It’s not from Phenacodus, though as the deposits are far too young. Does anyone have any ideas on a better or more specific id? I’m not well versed in Cenozoic mammals. Thanks in advance.
  2. Hi everyone, these days I was thinking about sabertoothed animals (I know I'm a bit crazy). I was thinking about the difference in the canine of different animals, I know the difference in the sabertooth of machairodontinae, smilodontinae and metailurinae. I also know that thylacosmilus has triangular shaped canines. But what about barbourofelids and nimravids, are there difference that permits to distinguish their canines with felids sabertooth? Thank you to anyone who can enlight me
  3. I found some bone fragments up in some ogallala formation in Kansas. I also found this complete tooth I was hoping someone could identify for me.
  4. Miocene horse tooth from calvert cliffs?

    I found this land mammal tooth at Flag ponds on Calvert cliffs. It got me really excited when I found a mammal tooth, But I have no idea what it is. I was thinking Camel or horse because that is what it resembles. If anyone can help me get a positive ID on this that would be great!
  5. Hello everyone, I want to tell you my first experience with Microfossil. (I can't stop anymore, it's a drug). Anyway, last months I worked in the paleontology museum of my university. My role was pretty much to be a factotum but in particular I had to rediscover all the fossils that are in the deposits and in the basement. I can't describe you the tons and tons of unknown material there is. We already found many interesting and never described pieces. Anyway, back to our story, in the deposits there where dozens of bags full of fossiliferous sediments from Cava dell'erba in souther Italy a lower pleistocene/pliocene site known better for the macrofossils (Pirro Nord fauna). The bags need all to be sifted cleaned and studied, looking also for human remains. Three of these bags were unfortunately broken and all the sediment was mixed making it completely useless for any study (the sediment come from carsic fissures so the level and the position is very important). So the museum director told me that sediment was going to be thrown away, or if I wanted I could bring it at home. I clearly took it with me, I washed sifted and collected and here are my preliminary results. The photo represents all the teeth and mandible I found there are insectivors rodents amphibian, there is also a canine (from what it can come from? It's the second from right in the second row) I still have a bag to study and tons of bones to identify, I'm gonna ask you some help very soon
  6. Post Oak Creek 12-10-20

    I went back to a new spot on POC and found the typical array of broken shark teeth, a few Ptychodus teeth, and some interesting items I'm not really sure about. Anyone have an idea of what the item in pictures 6-8 are? What about 9-11 maybe coprolite or a fossilized crustacean? The item in pictures 12-14 appears to be a tooth but with no enamel I didn't think it was a shark tip. It could also just be a piece of bone or something. Sorry for the poor picture quality of that one but I will take better ones of it later. Im pretty sure picture 15 is a rudist and lastly the item in pictures 16-18 I think is just a coincidentally formed rock. The rest of the pictures are of some cool items like the shark or fish verts, the small fossilized crab claw, a broken piece of sawfish rostrum, and a few cool pieces of matrix with inclusions. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18.
  7. Tibia identification

    This is a cave find I can't place. I think its a partial tibia, but from what family? The identification of this bone could help me with the time-line of the cave. Thanks
  8. Teeth Pleistocene

    Two teeth here. I think both are from the beach in Jacksonville Florida. Although, the first might have been from a phosphate mine. I can’t remember. They look like they might be canines?
  9. Crazy Beast From Madagascar

    Dr Krause does it again. Another mammal from the Cretaceous of Madagascar. Named the "crazy beast" in hybrid Malagasy and Greek. Also named after a colleague who passed away. Weird reading about people you've worked with and met. My wife did unrelated research with Dr. Hu too. Don't get fooled by the picture at the top of the page, it is from a gallery of extinct creatures https://www.cnn.com/2020/12/18/world/crazy-beast-fossil-mammal-scn-trnd/index.html
  10. Mammal Tooth

    Interesting mammal tooth found scanning a Monmouth County NJ stream today. Can anyone help identify? Old or new? Cretaceous stream
  11. White River Teeth and Astragali

    All from Nebraska. I thought the last astragalus was Mesohippus at first, but it seems much flatter than the other Mesohippus ones I have. Any and all help is much appreciated.
  12. Found this odd 9" long jaw-like fossilized bone in a small creek within the Yorktown formation in Virginia between the York River and I-64. It is atypical of the Baleen Whale and Ice Age mammal bones I have found in the same area. Any help with identifying this specimen would be appreciated.
  13. Skull ID

    Hello, new to the forum and looking for some help with this skull cap I found. It was found on the Kansas River in central Kansas after heavy rains. I included one picture exactly where I found it and a few pictures of it now after it's dried in my garage. It's approximately 3' wide and very heavy. I have an idea what it might be but would like to hear some opinions. Thank you for any assistance.
  14. Finds from Thorness Bay

    Hi My wife and I found these three fossils yesterday at Thorness Bay on the Isle of Wight. They were beach finds rather than in situ but the rocks there are Bembridge Limestone and the Bembridge Marls of Eocene age (and pre Grande Coupure so older than 34ma). I think that A and B are mammal calcaneum but am not sure of species (or even if it is possible to identify to that level from the bones I have) - Any suggestions to help with identification or sources I could use to identify would be very much appreciated. Item 3 is a mammal jaw, I think a left mandible, I am pretty sure that it is from a Plagiolophus (major as it is quite large) but again would appreciate confirmation or knowledge of a good source for ID's as what I have access too is quite limited for identification purposes. Thanks in advance Martyn
  15. Claw Core and Hoof Core?

    Happy Thanksgiving to everyone! I really appreciate this forum and the people willing to take the time and effort to answer everyone's questions and help people learn. I found these two fragments on the Brazos River in sandy gravel and low water near Brookshire, Texas. Mostly Pleistocene era here with some Cretaceous shells also I think. FRAGMENT ONE: CLAW CORE? The photos I'd seen of claw cores made me think this could be one, but since it's not very well defined, I've been wondering if it's even animal related at all. The most similar example I could find was a turtle claw core documented by @Harry Pristis , as seen here: Am I way off base? The flat smooth side and holes made me think it was vascular tissue, but I've wondered if it might be reef or even some type of mineral instead. FRAGMENT TWO: SMALL HOOF CORE? This looks like a very small hoof fragment with a rounded top and very flat bottom. The exterior looks worn on the toe-tip area and broken off toward the top. I had trouble finding anything that looked similar online. It does seem very small compared to several other hoof core examples I've seen. The closest thing I could find that looked a little similar was this camel hoof core fragment documented by @worthy 55 As usual, any help would be appreciated, and thanks to anyone who takes a look. --Brandy
  16. Hi all!! These were found along the Venice, FL beaches this past week (along with other items that like dozens of shark teeth, a sand dollar, lots of shells, etc). My extreme novice research says the common epochs here are Plio and Pleistocene (but spans early Miocene through Pleistocene epochs from what I have read), with the main formations being undifferentiated shellbeds, Caloosahatchee formation, Tamiami formation, and Fort Thompson Formation (although I've seen geo material reference others as well like the Peace River Formation, which I know is popular on TFF, but unsure whether it actually encompasses Venice Beach area). From reading the forums, it seems that Venice is already well known by members, so I suppose I am mostly writing out this info above you so all can correct me if I am wrong! Could anyone else identify any of these? I have a few guesses, but that is about it. Set A really interested me because of what looks like fossils within in them - maybe I am just seeing things though *I didn't put much focus on the shark teeth (this was just a group of the teeth found on 1 of the days). I am really interested to learn how to identify other items!
  17. Hi there I've always wanted a sabertooth skull, and for the past year i see many coming the same seller among other fossils from our favorite auction site. They never really explain how much of the skull, eggs, pssitacosaurus, is authentic and not responded to messages. Do you recommend these products? Thanks!
  18. Virginia mammal tooth

    Hello! i recently found a small, broken mammal molar. The occlusal surface is worn flat partially, this maybe difficult to see from the photos, it seems small to be an older pig, but pig was my first guess. If that is correct I guess it would most likely not be a “fossil”, although it seems to have some qualities consistent with mineralization. Is it conceivably human, about the same size and in better shape than some of mine! Very curious find for me and probably obvious for some members. thanks for your time!
  19. Chunkothere? South Texas

    Found on Padre Island Pleistocene watering hole was nearby 6000 - 8000 years ago. What kind of bone? Hopefully not a chunkothere
  20. Small pleistocene jaw from what?

    Hi all, found this partial jaw a couple of weeks ago and I'm a little lost on what animal species this could have belonged to. If it is a terrestrial mammal it would be pleistocene in age, if it's a cetatean it could be miocene-pliocene in age. I am leaning towards terrestrial origin though. Anybody recognise this jaw fragment?
  21. No Social Distancing in The Cretaceous: New study finds earliest evidence of mammal social behavior https://www.washington.edu/news/2020/11/02/mammal-social-behavior-cretaceous/?utm_source=sendinblue&utm_campaign=1132020&utm_medium=email
  22. A few things I’m not sure on

    All found on the beach in Jacksonville Beach FL like twenty years ago. Area known to produce Pleistocene mammals. 1. Thinking sloth phalanx. Note proximal epiphysis is missing/unfused. If it is sloth, does anyone known what kind? Is it medial? 2. Guess is bison first lower premolar 3. Equus sesamoids? Any help is appreciated.
  23. Found this unusual tooth at GMR

    I found this unusual little guy in my screen at GMR. I don't think it is fossilized, but I was hoping someone out there recognized the tooth. My guess is racoon, badger or something like that. Thanks.
  24. ID please on this mammal tooth

    Hi all I have been looking at old boxes of fossils to find some goodies for my Secret Santa and I found this tooth. Label says, found 1988 , near Stratford upon Avon. from the period of the Devensian Glaciation. I think it is a bos tooth but an ID from the forum would be really great. Thanks for your help. have a nice weekend. Bobby
  25. Partial lower jaw from a mammal

    Hello there, I recently acquired this fossil, which seemed to me a partial lower jaw from a mammal. Can anyone help identify this particular fossil? Also, this mammal appeared to have an impacted third molar just like humans!!
