This rock caught my eye in a stream bed (SF East Bay area, CA, USA), so I took a couple pics and left it. Okay, my mind is blown how the curvatures of this match the femur head of various ancient beasts. Even the different sides seem to match, but it can't be right? Just a rock right? Do you think its worth going back to get some better pics? Thanks in advance. P.S. - Sorry no scale reference, it was maybe 6 inches across.

When hunting, I usually have numerous bones which I am unsure about identification. Depending on how much time I have , more of these bones get posted. I have 4 in the same location. I thought this might be a hoof core of a really huge animal. but the only possibilities seem to be Eremotherium and Gomphotheres. I know Mastodon does NOT have foot bones like this.... Maybe it in not a foot_bone... Here is something similar in size.... https://www.worthpoint.com/worthopedia/huge-mammoth-mastodon-fossil-toe-ankle-bone

Bonjour all fellow collectors, my aut gave this bone to me years ago. They are pleistocene / early holocene specimens collected in Po valley in the '70. Do you have any ideas about what they might be? Thanks to all of you.

The kids and I were recently on a sandbar in the Kansas river and came across some bones. I believe there are bison bones, though some may be more modern. the first is appears to be a vertebrae.

Hello, fellow Fossil Forum members. Last summer I found this bone fragment in Crystal Beach, Bolivar Peninsula, Texas. The fossils from the upper Texas coast are from the very late Pleistocene Beaumont formation. At first, I didn’t think anything of it, other than it just being a bone fragment. But now I’m thinking it might be a very worn down claw core from some animal. But I’m not sure, it could just be a plain old bone fragment. So let me know your thoughts on this specimen. Front view- Specimen measures 30 mm (1.2 inches) long side view back view- showin

A collector/dealer recently donated to our museum a small collection of Pleistocene vertebrate fossils (mostly mammalian) from Florida. Only a few items were labelled, and he could not recall any provenance for some of the material. Even though the material was poorly provenanced, it will make a welcome addition to our comparative collection of Pleistocene vertebrates. Can anyone help me with the provenance for the llama/camel (cf. Hemiauchenia) calcaneum in this phone-camera snapshot? I thought the attached oyster shells might help in narrowing down the possibilities.

Hi all, I found this fossil vertebra near the Zandmotor (Netherlands) last weekend. It's from the last Ice Age, late Pleistocene (around 40'000 years old). There is the possibility that it is middle Pleistocene (around 600'000 years old), but that possibility is very slim. So it's (most likely) a fossil vertebra from one of the typical megafaunal Ice Age critters that roamed Europe alongside the mammoths, woolly rhino's, etc. For now, I am thinking it could be from some deer species, but I am really not sure. What are your thoughts? Thanks i

Dad and I spent a day in a creek near Tambar Springs, NSW on Monday looking for Pleistocene fossils, and we found a few nice things. It isn't the most productive site, so not a bad haul considering our short time there. Some unidentified bone fragments: Macropus sp. calcaneum(?). Forgot to add a ruler, it is 8cm x 3.5cm

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.

Hello! Dad and I recently went on a fossil trip to Tambar Springs in western NSW Australia with the fossil club and another forum member. This is some of the stuff that I wanted to get IDed(?). Also sorry about the horrible pictures and if you need better ones to identify them I will try. I took pictures with a potato. These were in creeks on flood planes. The sediments they were in had been reworked or in gravel beds. The bones are Pleistocene but I'm not sure of an exact time. And as I said, they werent in their original formation so I don't know what formation they

Collected in a creek bed near Gunnedah, NSW, Australia. The sediments date back to the late Pleistocene about 52 000 years ago and contain fossils of the Australian megafauna: kangaroos, diprotodontids, marsupial lions, crocodiles, birds and various others. The bone is 75 mm long and as you can see is almost dead straight! There is a circular cross section with thick bone walls at one end and a generally circular cross section with thinner bone walls at the other end. I first thought some kind of bird limb bone, but the thick bone wall at one end didn't make sense. Now i am thinki
