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

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?

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.© Harry Pristis 2021

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

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 t

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.

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.

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!

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

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?

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 t

Hi everyone, I found what I think are a lumbar vertebra and an astragalus bone. I'm not sure how old they are, but they both seem pretty weathered and possibly mineralized. Both appear to be from bovids(?). These were found on a river sandbar around Ames, IA after recent spring flooding. Does anyone know how to distinguish bison from cattle bones? The vertebra is 35 cm wide, 10 cm long, and 8 cm tall. The astragalus is 7.4 cm long, 5.5 cm wide, and 4 cm deep.

Edit to add: more likely a phalange This was found in the river at the confluence of the Blue Earth and Minnesota River in South Central Minnesota on August 3, 2018. It appears to me to be an astragalus, the size of that of a white tailed deer, but the shape is not quite right. It matches none of the astragali found in Miles Gilbert's Mammalian Osteology. The "bump" at about the 4cm mark in two of the photos seems like a very distinctive feature, yet I cannot find an identification for this.

hello all, I found this astragalus bone from Miocene/ Pliocene Siwaliks. i am curious whether it is of camel or of bovid.

Horse Teeth 'Modern' horse teeth are very hypsodont (high-crowned) to deal with wear caused by eating gritty and/or fibrous foods like grasses. A mature horse may have as many as 44 teeth, which include: 12 incisors (6 upper and 6 lower) Canine teeth are usually absent in female horses but may be present in males. Cheek teeth (4 premolars and 3 molars per side) have very complex enamel patterns. The first premolars (upper and lower) in horses (sometimes called the 'wolf teeth') are vestigial and often absent. Upper cheek teeth (premolars and mol

Hi people! A friend of mine collected the astragalus of the photo from a fossiliferous site with Pleistocene mammals in southern Brazil. Although we have a large collection of fossils at the university, we couldn't identify it. We have already excluded horses, tapirs, ground sloths, sabertooth cats...could it be a bear or possibly a mastodont?
