    Here are the shots of the mandible and teeth. Alligator? Also curious as to how I can clean it without causing damage.
  3. Novice seeking ID help

    With help from my photographer wife I can provide the following MUCH better photos. Here is the individual tooth. Original photo showed bite surface. these are bottom and sides. If not Tapir, what could it be?

    A sketch idea after Escher’s Curl Up I’ll have to come back to when I have time.

    Tim - thank you for lightening the picture. looks much better. The picture is of the chewing surface the opposite side is the root (only 1/2). I will reshoot different angles of both items and repost to possibly help in the ID. Harry - Any idea if not Tapir?
  7. Fossil fish

    Hmm. I see. Got it.
  8. Novice seeking ID help

    Welcome to the Forum. The tooth doesn't appear to be from a tapir, but the image is too dark and unfocused to say with confidence what it is.
  9. Bob the Baby T-rex

    How very sad. I can only hope the buyer will do the right thing and make it available for study.
  10. Fossil fish

    Yeah, I know what you meant. Just thought I'd have some fun with semantics. You know, perception of reality IS the reality one perceives.
  11. Novice seeking ID help

    Welcome to the Forum. Well lit pictures of the mandible from all directions would be helpful. Also, an image of the chewing surface and other side of the tooth will help as well. First image, brightened and cropped.
  12. Fossil fish

    No. That's a bit convoluted. Haha. I am saying that Green River material is very abundant, and sold around the world. Any gift shop or specialty shop in Austria would more than likely sell these fish from the USA. Therefore, ... the likelyhood that this is from the Green River Formation in USA is pretty high.
  13. Fossil fish

    So what you're saying is that it didn't come from Austria even though it came from Austria, but it came from Green River because it's abundant in Austria?
  14. Florida laws- help!!

    Hi all, I am about to go on a hunting trip without a guide- my first! I’ve read a lot about the Florida laws for fossil hunting.. and I have some questions. I’ve read that any bridge on a road is a public access point to a river or creek- is that true? Also, is there a limit on shovel size? I’ve read that “hand shovels” are allowed but are regular shovels? And last, how do you know if the river or creek is on private land? I know you can’t dig on private property but are all creeks and rivers public but not the river/creek beds? Should I stay submerged at least until my knees? Thank you in advanced- sorry for the newbie stuff. But yes I know about getting the fossil permits for verts, no worries there
  15. Novice seeking ID help

    I am a novice fossil hunter seeking some confirmation on a couple of finds in the Peace River, FL this week. I believe the images in the attached photo are a Tapir tooth and Alligator jaw section with two teeth. I would appreciate help in confirming or properly identifying these finds. I am also interested in information on how I can clean the "Alligator" jaw/teeth to remove green algae without damaging the specimen. Thanks
  16. Savannah land based question

    Sounds good Jack.
  17. Unidentified crocodile bones from Holzmaden

    Hi Paul, thank you That would be absolutely awesome Do you have any pictures of similar (plesiosaur) bones?
  18. Kamp Ranch Texas Ptychodus Teeth

    fossilsonwheels, I think that Heteromorph's P. whipplei ID is probably correct for the first two. However, just to make certain, can you send a side view of the tooth from the side? There is another possible ID depending on crown height. If you could send measurements of the tooth width vs tooth height vs crown height, that might also be helpful.
  19. Giant Tortois Osteoderm?

    Oh man, I can't imagine how many of these I've tossed back.
  20. Help me identify this ground sloth...

    Your best bet would probably be to contact a vertebrate paleontologist or a zoologist who specializes in sloths.
  21. Help me identify this ground sloth...

    Thank you Mark for that correction, I'm glad you still knew what I meant to say
  22. McKittrick bird limb bones....but from what?

    Last bone, in matrix
  23. McKittrick bird limb bones....but from what?

    Here ya go, Scale in cm. Here are the three longbones. there are 3 photos: a full shot, and of both ends. This is side one
  24. Dear researchers, I was collecting these scales and bones of teleost fishes in flint erratic boulders of South Lithuania 1-4 years ago and I still do not know which fish families these several strange finds belong to. The other remains are identified and judging by that taxa I think the majority of these fossils are from recent families. The flint origin is deep sea or ocean so some strange taxons like fangtooth, lanternfish or other can be possible. If here is an ichthyologist who knows more about recent fish scales, I would be very happy to get an answer. The scales are 2.5- 9 mm length, pointy skull bones are from 5 mm to 1 cm length. Best Regards, Domas
  25. Giant Tortois Osteoderm?

    I'd accept Hulbert's diagnosis of sesamoid. Certainly, Chris is correct that a patella is a sesamoid; however, patellae are consistently shaped by the contiguous bones, thus they are diagnostic. Not so with other sesamoids (perhaps with the exception of some pisiforms). The other bone is definitely a giant tortoise osteoderm. Here is a description taken from Palaeo-Electronica (March 2010) which divides mammal bones into two types: 1. endochondral bones (which ossify directly from an embryonic cartilaginous precursor, often constrained by joints and articular surfaces). These would include all limb bones, for example, and, 2. intermembranous bones which are less constrained. Some intermembranous bones, such as the kneecap (patella), are almost always ossified in adult mammals (with minor exceptions). Other intermembranous bones, known as sesamoids, occur only in areas where a tendon passes over a joint, and ossify in irregular and unpredictable patterns. Humans have only one sesamoid, the pisiform in the carpus. Sooo... How can a collector identify a sesamoid or patella when he's sifting gravel or checking another collector's discard pile? Sesamoids (particularly pisiforms) and patellae have articular facets, often two facets, on what may be an otherwise undistinguished lump of bone. How can you identify them to species? ...You'll have to take 'em to the local museum where they may be able to help you. _________________________ Comparative Variability of Intermembranous and Endochondral Bones in Pleistocene Mammals Kristina R. Raymond and Donald R. Prothero Palaeo-Electronica (March 2010) "The topic of intermembranous and endochondral bone growth, size and variability is one that is not commonly touched upon, except briefly in passing, in paleontological literature. Generally, intermembranous bones are measured and discussed as only a slightly relevant topic in regards to larger studies of species or interspecific variation and sexual size dimorphism. "Intermembranous bones form directly from the connective tissue late in embryological development and after birth through intramembranous ossification. Some intermembranous bones, such as the kneecap (patella), are almost always ossified in adult mammals (with minor exceptions). “Other intermembranous bones, known as sesamoids, occur only in areas where a tendon passes over a joint, and ossify in irregular and unpredictable patterns (Vickaryous and Olson 2007). "The number and shape of intermembranous bones vary greatly within the Mammalia, and are highly taxon-dependent. Humans have the patella and only one sesamoid (the pisiform) in the carpus. “In many mammals, such bones include the patella and large sesamoids in the manus and pes. In ungulates, on the other hand, the only [relatively] large intermembranous element is the patella. The sesamoids in the manus or pes are small nodular ossifications in the digital flexor tendons, both at the metapodial-phalangeal joint and the distal interphalangeal joint; suids have as many as 13 sesamoids in the manus alone."
