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- showing different coloration on the interior another side view The bottom view- it has a black coloration. The bone fragments from this formation are often multicolored.

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. I was given a verbal location for this specimen (there was no label), but I am skeptical. Thank you!

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.

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 in advance, Max

What is this fossil tooth from Dakota? Found in the 1980's, the location is not know, perhaps from near Belle Fourche, Butte County, South Dakota, USA.

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 originated from. Fossils found there included all of the modern stuff found there today and things that are extinct or just extinct in that area. 1. Small insectivore jaw with most of its teeth. It is bizarre because one row of teeth are in the jaw but the other row of teeth isn't. I have no idea how they remained in order.

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 thinking kangaroo metatarsal but would like more opinions.

Need help to identify these bones I pulled out of a cliff, if anyone can help that would be great! I have more photos if needed. I'm thinking bison, or some type of mega fauna.

Hi everyone! I hope you all are spending the summer finding some really neat fossils. I am currently working on a commissioned illustration for FossilClaw, and am shooting to have a sketch up soon. However, we would like your opinion on the landscape and fauna... We are definite that there will be both woolly mammoth(s) and woolly rhino(s) in the scene, but we are not sure what other animals may have shared the same territory on a regular basis with these creatures. Initially, we were shooting to have a Cave bear in the scene, but given the different habitats (and altitudes) it has proven a challenge. What other animals would plausibly fit in the scene we are trying to depict? Megaloceros? Sabertooth? Bison? Wild Horses? Any other predators or interesting animals? The landscape will be steppes. Really appreciate your input!! -Lauren

From the album Aussie Megafauna
A megafauna jaw I repatriated from the US. Its labeled "Sthenurus sp." but I'm currently doing a little detective work to determine the validity of this and pinpoint the species.
