    A rare find

    Out today with a good friend. It seemed to be his day 5 Horse Teeth, a Bison Astragalus, and 3 decent Megs...On the 1st sieve, I found an incisor and an hour later a small predator astragalus. The rest of my day was mostly small shark teeth until the very end. We went to a spot where we had super success for a couple of years and coming back first time this season.. It has 6 or 8 feet of large fossil producing gravel, but 4 feet of sand had rolled over that gravel and added about 4 inches of new gravel on top of the stand but that gravel contained few fossils beside those small teeth... Here is the incisor... I think it is Llama, but very small. Could it be wild pig? and the Predator astragalus... Harry identified a very similar one as Raccoon 2 years back, and finally the star of my day, This is a Miocene fossil (7-14 mya) and Rare !! Only my 5th in 15 years . A great reward for my efforts today... A high quality tooth, barely erupted...

    Is this an astragalus to an rodent?

    Is this an astragalus to perhaps an insectivore, squirrel, or other type of rodent? Found in the Nebraska badlands – private ranch – early Oligocene, Brule Formation, Orella Member, about 20 feet above the Upper Purplish White (UPW) ash layer – a Harvester ant mound specimen. The bone (3 to 4 mm in length) has a rounded end which I never seen before on any astragulus. Two specimens photo’ed in this post. Any help in ID’ing this fossil would be greatly appreciated, Thank you.

    Odd shaped astragalus

    This one looks quite a bit different than the rest of my astragali. Any ideas what critter it came from? Found in North Central Nebraska. @Harry Pristis
  4. I had tossed all these together in my garage storage and just noticed, while I was looking for auction material, that they were not all Equus astragalus. Given their condition, can ID's for the bottom 3 be determined? I'm assuming Harry, @Harry Pristis, would be my best shot. I appreciate it!

    Peace River - multiple IDs needed

    So was out hunting yesterday - and I will definitely be making a trip report because I came away with a ridiculous number of amazing finds. But before that - I need ids! So to start off - 1) Found a massive astragalus. 2.5”/64mm. Matches Equus, but these astragalii I found a while ago were IDd as Equus and they are about half the size: One from yesterday: So is the new one Equus and my old ones are 3-toed? 2) Found a symphysis from some mammal. It’s still got the incisor roots, and an unerupted canine, but I can’t see the canine well enough to figure it out. Diagnostically though - it’s got part of the left mandible, showcasing the roots and sockets of the closest premolar (and one socket from the next) - and based on the distance I think it’s okay to eliminate herbivore (Or deer, horse, camel/llama, etc) due to knowing they have long snouts. So… carnivore? Any ideas what, if so? Measures 50mm/1.95” long and 30mm/1.2” wide. 3) Finally - pretty sure this is the tip of a Dire wolf canine, given root hole shape, the single carinae, lack of striations, etc - but I’d love confirmation or another ID. @Shellseeker @Harry Pristis @Brandy Cole Thanks all in advance!

    Tiny astragalus

    This is the smallest one of these I have ever seen. Any ideas of what critter it may have belonged to? Found in North Central Nebraska Measures 20mm X 12mm.
  7. Hey everyone! Found this astragalus this past weekend. Not sure if it’s deer or peccary, or if it’s too worn to tell for sure. Measures 38mmx19mm @Harry Pristis @Shellseeker
  8. Found this today - recognized it as an astragalus pretty quickly but couldn’t pinpoint what. I’ve narrowed it down to either Probiscidean or Sloth. It’s 3.2 inches/82mm in length. @Harry Pristis @Shellseeker either of you able to discern?

    Glyptodon Astragalus

    Identified by Richard Hulbert as a Glyptodon Astragalus. One of two, to his knowledge, that were found as of the time of collection of this specimen. Notable features include a shape comparable to the astragalus of the Giant Armadillo - Holmesina, with overall larger features to account for the greater size in G. floridanum. Reference: Simpson, George Gaylord. (1929). Pleistocene mammalian fauna of the Seminole Field, Pinellas County, Florida. Bulletin of the American Museum of Natural History 56: 561-599.

    Capybara, maybe sloth

    Last August, I found a broken bone. The unbroken part reminded me of a Rhino astragalus. I posted a Fossil_ID thread but not much feedback, The following week I did some internet searching for fossil astragali... and found this one for sale by @PrehistoricFlorida. I thought that I found an ID match !!! This Capybara astragalus has many characteristics of Rhino , also Cutting to the chase, a member PMed me on some of my Capybara finds Friday and I started searching the internet . I found another fossil on @prehistoricflorida 's website.. This time an Eremotherium fossil. Did you get a good look at this 3 inch Eremotherium medial phalanx, compared to my August find.... Could it be Sloth rather than Capybara? and by the way.... here is a look at the bones in a sloth claw... and the bone next to this claw (P. harlani ??) is also a Sloth medial phalanx !!!! Some times you have to take a circuitous route to a fossil ID... So what say you? Did I find Capybara or Eremotherium or something else?

    Bone Valley Astragalus ID Needed

    Found this Astragalus today - and I can’t figure out if it’s Horse or Tapir. Seems too big to be a tridactyl horse astragalus, but the deposit I was digging in does NOT contain Equus - only tridactyl horse fossils have been found. Which leaves me thinking Tapir. @Harry Pristis @Shellseeker

    Astragali

    Out hunting yesterday... went by myself. Not always a wise choice. But I was a Boy Scout some eons ago. Always be prepared. Heavy rains in the area increased the flow rate. Going a little faster than I should have on the way back, caught a log 6 inches below the surface, flipped the kayak as neat as you please. Having experienced this before, everything was in the hatches or lashed down, paddle leashed, no hat ,no sunglasses. Had my sit_in kayak, so as I resurfaced , grabbed the side of the cockpit and my weight pulled it over upright... along with 10 or 15 gallons of water. The water was well over my head, so I grabbed the kayak leash and dog paddled toward the bank while the current moved me and kayak rapidly downstream. Took me 10 minutes to empty the cockpit with a siphon hose and small bucket, which I always keep in the forward hatch for exactly this situation. On top of that excitement, I had a really good hunting. Lots of fossils, nothing spectacular. So, I pick and choose what to ID first... I found what I believe to be 2 Astragali.... First up, one that I have found many times before , and using @Harry Pristis gallery and pictures, identify as a camelid. It is too small for Bison and not cow due to position of the medial tubercle.. If anyone has knowledge, I would like to know if this is Palaeolama mirifica or Hemiauchenia. or Next... and even though it is badly broken, I am excited by the potential.... I have seen this before but NOT at this location. To give you a sense of where I am going... Capybara has a somewhat similar Astragulas, and the closest comparison in my collection is a (much larger) Teleoceras Astragalus I found in the Peace River in 2014 (photo below). The more realistic part of me is thinking a modern wild pig which can get up to 400 pounds wandered into my hunting area.

    Bone from Venice Beach, FL

    Any ideas what this bone is? I found it on Casey Key, FL near Venice Beach. Looks modern. Thinking maybe an astragalus or epiphysis of a bone?

    Rhino - Equus astragalus compared A

    From the album: BONES

    Two perissodactyl astragali, illustrating similarities and differences. Menoceras cf. M. arikarense is a small, cursorial rhino from the Early Miocene of Florida. The Equus sp. astragalus is much more massive.

    Would this be bison astagalus?

    Found in the Peace River, I think it is bison astragalus or horse, not sure. Please comment. Thank you. 1E5CE109-5BA3-4F17-8C50-B920953CEE3D.heic CEDBC9CE-394A-4302-8548-FC939C5EC7F6.heic CEEE7181-8D5B-4CFA-AA1D-7B8F1F28DD84.heic AB8E0575-9298-4C5E-8539-B5E09A2DE1AF.heic
  18. Over the past few years, I have been collecting(purchasing) various bones of the giant armadillo, Holmesina septentrionalis from the internet. My goal is to eventually build an entire skeleton. Since I live in Colorado, purchasing bones is my only choice. Recently I purchased a left astragalus bone and decided to try and create a right astragalus with my 3d printer. Using my iPhone, I took about 50 pictures of the bone at various angles against a white background. Using Agisoft Metashape and Meshmixer software, I was able to create a 3d image of the bone. This took some trial and error. YouTube instructional videos were very helpful. The 3d image was then loaded into Cura software and printed on my Ender 3 Pro printer. See image of the final painted bone. On the left is the original bone, on the right is the new 3D printed bone.

    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.

    Rhino fossils?

    Im trying to identify these fossils. I'm thinking that they are from a rhino species. Can anybody confirm or recognise these as something else? I have no information on them, but I'm guessing they are local South African and could have been found on the west coast miocene-pleistocene deposits as it looks like specimens from that area.
  21. This was found on a Florida beach after a storm near Sebastian Florida. Pretty large bone in my estimation, but you can see the dimensions in the photos. About four inches long. I think it might be an astragalus, but I haven't able to match it with a particular animal. The grooves on the inside of the two lobes seem to be deep. (Just below inch three and four on each side of the center channel.) I didn't see anything like that on the various photos for the animals I found. Must be fairly large though. What do you think? Thanks much!

    Perissodactyl Astragalus

    Both of these astragali were found on the Brazos River southwest of Houston. The larger of the two clearly belongs to Equus, but the smaller one continues to stump me. I know by the shape that it definitely some sort of perissodactyl, and although it resembles the shape of the Equus astragalus it is much, much smaller. The taller of the two ridges (I'm not sure what their name actually is) on the proximal end of the bone has been worn down by water or time so that it seems almost level with the other. If it were still present, these two astragalus would probably be identical. It occurred to me last week while looking at it again that it might be from a three-toed horse since they were a lot smaller than the more modern species of horses that prevailed in the late Pleistocene. Is there any way to tell? Or is it just from a younger Equus individual? Thanks for the help!
  23. Found in SouthWestern Pennsylvania. I’ve been told this is probably an Elk Astragalus definitely Bovid. How can I rule out cattle? What are the measurements of an Elk Astragalus?

    Astragalus bone of unknown critter

    Hi all, Apologies if I ruffle feathers with my ignorance of how things work around here but I did check out the posting guidelines. An initial and sound ID of the type of bone was made by the "Fossil Guy", Paul Murdoch, but it would be nice to narrow it down a little more than that. I've attached an archive of photos of all angles of the bone. The specimen weighs 99 g, and has overall dimensions of 77 mm * 52 mm * 39 mm, and I can do a displacement test to get its true density and volume if that helps with the ID. The fossil (so far unverified IN PERSON but passes match and taste test; taking to the ROM in Toronto for ID next week) was found off the north coast of Prince Edward Island while snorkeling in August of this year. It looked like a chunk of electrical insulator half-buried in the sand, but when I dove down to retrieve it, I noticed that it didn't feel like any material I've ever handled before, so I took it back and let it dry. This was found in 50' proximity of 30' tall red sandstone cliffs, being eroded by the warming waters of the gulf of the St. Lawrence. Based on the red staining of the specimen, I suspect it's a part of a skeleton either distributed along the bottom of the ocean in the area or still in the side of the cliff. Any help in narrowing down the age and former owner of this bone would be much appreciated! I apologize for the zip file but it only contains images. Thanks! James fossilphotoswithscale.zip

    Astragalus

    Found a fairly large astragalus, which I suspect might be from the Giraffidae family... Any takers on a more accurate ID?
