I found something from our favorite auction site that looks very interesting, however I have my doubts if it is legitimate or allosaurus, and would like to hear someone else's input. Seller describes the item as a fused humerus and radius, but I am guessing they mean ulna and radius, of an Allosaurus, found in the morrison formation. Do anyone have information regarding whether these bones even fuse in theropods, or whether they even resemble the ulna/radius bones of Allosaurus? Thanks

This is a ulna fossil of Panthera leo spelaea from Heilongjiang Province of China,It comes from the late Pleistocene.The length of the ulna is 44.7 cm,and it's very well preserved.Panthera leo spelaea is really a giant of Panthera.

I've had this partial ulna in my collection for many year's, found in some Pleistocene river channel mud deposits in the UK. Labelled it up as Bison due to the amount of Bison material in the area. But after showing it to a collector of similar finds we have agreed that it's not Bison but could possibly be from a carnivore. Can anyone else see carnivore as well please. Can supply measurements and different photos if needed.

Found in iowa not sure what it goes to but its and ulna and its calicified

After posting ID questions on a couple of STH whale bones that were mostly unidentifiable, I decided I'd post images of the one whale fossil I have that seems like a slam dunk ulna (Aside from an easily ID'd ear bone.). It may be debatable as to which specific family category, but at least its location on the whale is pretty certain, right? Too bad it's a partial, but it's all I have. It looks a lot like one that is called Tiphyocetus temblorensis in an image from the California Academy of Sciences. Tiphyocetus Temblorensis Even the mottled coloring is similar. As I mentioned, this specimen is from Bakersfield, Shark Tooth Hill area specifically. While people may have seen a fair number of these, I thought it was cool enough to post an image or two of. And, people will be happy to know, I don't entertain any thoughts of its being part of a whale jaw. In fact, I'm over-jawed about having this one. Cheers.

Hi all, I found some interesting specimens from the Isle of Sheppey. Any ideas about what they could be? Probably around 50 million years old, Eocene. From the London Clay. My guesses are: Top: Initially thought it was a fish fang, but I'm starting to doubt it because the "tooth" seems to be the same material as the "jaw". Middle: Squalodon tooth? Bottom: A small animal's ulna? Thanks in advance. Jay

This is a recent find on a sandbar where I find land and sea fossils. Reminds me of a human fibula, but I really have no idea. I also found 3 turkey verts, sea turtle fragments and shark teeth on the same day. This looks like it will be easily identifiable, but can provide more info if needed. Thank you for any help you can give me. Holocene- Silver Bluff Back Barrier Complex: Georgia Coast near Savannah

I found this rather interesting piece on our favourite auction site. It's being sold as a croc vertebra. But it looks a lot like the ulna of an Abelisaurid from the Kem Kem beds. The resemblance with the ulna of Majungasaurus is pretty close. It's a little shorter, but the single bump on the one side seems to fit. While if it was a vertebra, it seems to lack a neural canal. Majungasaurus left ulna

looking trough some matrix I came across this little specimen. When it was complete it would have been 40 mm in length. Unsure of the orientation of the section of bone on left end and small section in middle is upside down, but due to this being very delicate, I am not going to play with it. The bone is hollow, thin walled and filled with calcite but the bone will chip easily so this is the only photo as specimen now in small case so as to not damage further. I am comfortable with this being bird as it matches the preservation of the other pieces found in the area. I assume it is an ulna due to the curve so it would be the only one known from this species. The other bird specimens from this local are assumed to be enantiornithine, but only time will tell for sure. Mike D'Arcy

I'm considering this bone which is being sold as the distal end of a Pteranodon ulna. I thought it would be really cool to have a piece of the king of the skies. My only problem is I'm not experienced enough to know for sure if this is Pteranodon. This was found from Kansas, but an exact name of the formation was not given. Help would be greatly appreciated!

I have been looking at this ulna bone from the kem kem, and wondering if a large isolated bone like this can be identified. It is about 26.5cm (10.4 inches) and looks like a chunk of one end in missing (which might make it harder to id). It seems to resemble this megaraptor ulna....

Found a ulna and tibia in a Florida river. We have a few guesses but we really can't place it. They were found next to a Mastodon. Please help

Last Monday, June 12th, was my first trip to the Calvert Cliffs, and while my haul is hardly breathtaking I was very happy with it since it was my first tooth-hunting trip ever (first pic). I did my best to try and i.d. the finds, but I'm probably off on some of them. In fact, looking at this again, I can see that the top middle one is probably the tooth of a Lemon Shark, not a Gray as I had labeled it a week ago. I didn't spend much time each time I stopped at a beach (I was kayaking from Brownie's Point), because I didn't know how much there was to see as I traveled south. Turns out, only that first run of cliffside beaches at low tide offered anything, but I spent most of the day paddling south past the rocky shore, wooden piers and private beaches. There were thunderstorms on Monday so I went yesterday, June 20th. This time I spent the entire time on those cliffside beaches at low tide. I'm pretty happy with what I found, though I'm sure it's pretty standard fare. As I was walking past one of the several landslides that spill out into the sea from the cliffs, I saw something sticking straight up out of one. It turned out to be half of a meg tooth (on the right, below)! I clawed around in the surrounding clay to see if the other half was anywhere to be found, but that search was as useless as I expected it to be. Looking down, I found what I think is a second partial meg tooth. I ended up finding a number of teeth visible on the surface of these landslides, but I didn't have any tools aside from a small hand trowel for scooping up stuff for sifting. I found some sort of bone in one of the landslides, and I *think* it's a partial cetacean ulna? Two other notable finds were what I think is a Shortfin Mako shark tooth and an Odontocete tooth- which, btw, I almost threw away. I didn't know what it was and it looked like something from a modern plant. It passed my completely silly squeeze test (it didn't fall apart like rotted plant matter), so I kept it. Well, now I know. So, are we allowed to dig around in those landslides? I know, aside from it being dangerous, that we're prohibited from touching the cliff face, but these landslides extend out from the cliff and most reach the waterline. Some of them seem pretty new, just based on vegetation -or absence thereof- on them. Anyway, I had a great day and I hope to return soon.

Hi! I just acquired this bone from a gravel pit in Germany. The guys who I got it from say its a Woolly Rhino ulna. I think this is probably what it is but want some of you guys to have a look. Thanx!

I posted this photos in my "Fossil Finds from the Peace River" thread in Member Collections. PrehistoricFlorida posted a reply in which he questioned the tentative ID I had for the piece, so I decided to repost it here & let all of you have a go at a solid ID on it. From my original post in Member Collections: "This one I didn't find myself. A rock shop near my job back in Florida had a "bone box" of broken fossil parts from the Peace River that a diver would sell in bulk to the owner. The owner would then resell the parts for $1 per piece. I saw this in the box & thought "That looks odd" & bought it. Looking through reference books, and talking to Tampa Bay Fossil Club members, we came to the tentative conclusion that it's the proximal end of the ulna of a sabertooth." A further comment I made on the piece was that the club members also said it was bigger than comparable sabertooth bones they had seen.
