    Turtle scute?

    I found this rock on Ocean Beach in San Francisco. I have In the same area over the past few weeks recovered several fragments of Sand Dollar fossils probably about two million years old, according to a local geology/oceanology professor who recognized them right away. I am wondering if this rock might be a turtle scute as I have seen similar looking samples online that were Holocene turtle scutes. The sand dollars were the first fossils I’ve ever found outside of fossilized clams so I have no problem if this is just a rock. Many thanks in advance for the expert guidance and help.
  2. Can anyone help me with the following fossils? (what species etc.). Made a selection of a bigger compilation (most important fossils are shown). Kind regards
  3. Can anyone help me to determine the fossils on the pictures? They are all found were bone fragments from Pleistocene and/or Holocene material has been found. Could the teeth belong to Bos primigenius (Bojanus, 1827)? I think they belong to the above mentioned art. I also found some horse teeth at some locations. The brownish coloured teeth are from Zeeland. The black teeth are from Limburg (found in water/creeks). They are black and/or brown and fossil (not recent material judging by the colour and erosion).

    Thoughts on cave bones?

    Hi all I have been looking through some of my cave finds and want your thoughts on two specimens that look much older than the other bones. All these bones where found in one cave that could have possibly been inhabited by humans as recently as 370 years ago, before colonialism. I have found some ostrich egg fragments as well as sea shells in the upper soil layer, this might be an indication of human activity, I have also found evidence that the site was occupied by scavengers and predators like the lynx and leopard at some points. The site is approximately 1.5km from the nearest coast an

    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

    Is this a fossil?

    I have here a polar bear tooth from St. Lawrence, Alaska. I was told it was fossilized, Pleistocene to be precise. The seller had other similar teeth available on offer, in darker shades, claiming they were all fossilized and simply preserved in different ways. Ultimately, I chose this one. As far as the literature goes, it has been argued that the polar bear does go back to the late Pleistocene: Ingólfsson, Ólafur; Wiig, Øystein (2009). "Late Pleistocene fossil find in Svalbard: the oldest remains of a polar bear (Ursus maritimus Phipps, 1744) ever discovered". Polar R

    Partial Jaw Bovid, Cervid?

    Found on a river gravel bar in southern MN.
  10. I know bone fragment ID's are usually left at just that "bone fragments," but I've seen some pretty amazing ID's here lately and this is my favorite little puzzle. It was found on Edisto beach which harbors Pleistocene mammals mixed with Miocene and Holocene aquatic creatures. More info on the location (including a list of mammals) can be found here: https://markgelbart.wordpress.com/2010/05/25/the-edisto-beach-fossil-site/ It's completely hollow and has what appears to be healed over bite marks. Even if it can't be ID'd, if anyone can confirm or deny if the markings are really bit

    Pleistocene-Holocene Frags

    I know this is quite a long shot but the pores/foramen are just KILLING ME, the shape is so familiar, but I just CANNOT drag it out of my brain. Location: Southern California, Mojave Desert. Quaternary alluvium/older alluvium (depth 8 ft) in an area where mammoths and camelids have been found (3 miles northwest, 5 feet below surface). Pleistocene dry lakes lie just to the east. The bones are at least somewhat mineralized, but obviously have a pretty high level of preservation. Pictured are two separate bones with very distinct shapes/pores/etc. No bones have anything particularly d
  13. Ahoi dear forum members. While reading a little bit about rudists some of the structures in picture of a broken Hippurites and the shape of Lapeirusia crateriformis reminded me remotely of a still unidentified beachfind from my last big holiday. That doesn´t say much, as apparently rudist could look like anything they wanted, but still I wonder what the fragment I found may be. Found it in the pacific driftline, broken like you see it. There are some barnacles, some serpulids, maybe a little bivalve also, but I wonder what the enclosing structure is. Any ideas? Aloha,

    Fossil Pelican horns?

    Hello again, I just read that the American white pelican ( Pelecanus erythrorhynchos ) grows a kind of horn during mating season that is shed when the eggs are laid. Has anyone ever heard of one of those being found fossil, or subfossil? I know that keratin is rarely preserved, I am just curious. Best Regards, J

    Barbados Fossils

  18. Hello folks, I wanted to share some photos of one of the mangrove lobsters (Thalassina) I finished prepping. It's from Darwin, Northern Territory, Australia from the Holocene-Pleistocene error. The matrix on this lobster was the hardest I've ever worked with.
  19. Found this partial tooth a few years ago in some Holo-Pleistocene marine sediments on Oahu, Hawaii. There is also the chance that it is more recent, as there had been some dredging in the area, though I haven't seen any evidence at this location. Approximately half of this tooth is missing. What remains is half of the crown and one root lobe. It is 17 mm in maximum dimension. My guess is carnassial. Seal? Canid? Appreciate any and all input.

    Possible ancient bison bones

    These bones were found just above Cretaceous gravel layer at a local DFW creek today. One the leg bones measures almost 17 to 18 inches in length. Leg bone width on this one is around 3 to 4 inches. I also found vertebra bone of bison as well. They look juvenile. These are probably either adult steppe bison bones or juvenile bones. Earlier this month, at a another creek, I also found steppe bison dorsal vertebra with rib bones within similar layer. Your opinion helps.

    Vertebra id

    Besides of the tooth and several other bones I also found some this vertebra: I am really not sure if its a mammal vert or something. Is it even fossil? I have my doubts.... Its from the area of Ijmuiden (Netherlands), so its probably from the Holocene. Can anybody help on the id? Again perhaps @LordTrilobite or @Harry Pristis ?

    Maybe ancient mammal bone

    In addition to the possible orthocone fossil I found in the same creek, I found this mammal bone. I live about ten miles as the crow flies from Big Bone Lick State Park in Kentucky. I live on a cattle farm (have had horses on the farm before as well spanning at least 50 years). This bone struck me as looking quite old due to the coloration and the slight erosion on it. With me living on a cattle farm, I’m leaning towards it being some sort of bovid bone, but want to know your all’s opinion. Thanks!
