Nice pick up. I agree with your ID.

I've made a better image of the piece that better shows which part it is and also uploaded it to collections.

Nice, your bone along with isolated teeth continues to confirm that there is at least one small dromaeosaurid in the Kem Kem.  Great addition and like you said very rare.  Good eye spotting it.

Thanks, I have another metatarsal bone that looks very similar to that of Deinonychus and Velociraptor. But that one seems slightly larger than Velociraptor. So if I ID'd that metatarsal correctly there might also be some slightly larger raptors around.

I fully agree with your Id! It is not anyone who is able to identify an isolated and partial bone with such mastery, and you my friend succeeded in accomplishing this feat! Congratulations on the experience and great luck in this finding. I wonder what this dromaeosaurid will be called if it is described scientifically ... Kemkemraptor saharicus? I like to imagine the future ... Keep this with great affection my friend, because your discovery is impressive! :wub:

Great piece, @LordTrilobite. Being amateur and even worse, not having ANY experiences with raptor bone, my examination of the proximal end of the humerus displayed had me puzzled.

From the examples provided, it is hard for me to envision a "ball and socket" joint in the shoulder. Am I wrong? Or is it a joint with very poor development, typical of the species, or raptors in general. Next time I see raptors on display, I will check them out a little more carefully. One gets caught up looking at teeth, not scapula/ humerus articulation.

Well, as you can see in the Bambiraptor reference image, there is indeed not much of a ball on the end of the humerus. My guess is that much of the socket was filled with cartilage, but I really don't know.

Due to graphic driver updates I was unable to make new photogrammetry scans for a while. But I have a new laptop and photogrammetry does work on there. So with that I'm making a number of new scans of my fossils I have in the works. Among those I made a scan of this raptor humerus so I figured I'd post it here in the thread, as it does show some nice details that really can't be viewed properly from just the photos.

Hi, I just found and joined this site, but this topic came up when I Googled "raptor humerus."  The reason I did is because last year I bought a number of Kem Kem dromaeosaur specimens, totaling ten teeth, eleven limb bones (including two fairly complete humeri), and seven vertebrae of various sizes.  I'd be happy to share photos of these specimens and get members' feedback on these.

 

I have attached a photo of some of the limb bones.  The second and third from the right I believe to be humeri, and resemble your partial specimen closely.  I will be taking some high-quality photos with my Nikon if there is interest.

Isolated limb bones can be pretty difficult to identify. But it's certainly possible in some cases. Perhaps you should make a new thread in the ID sub forum. Those specimens look like they could be interesting. Though I don't think they can be identified from just this one photo.

I agree; I don't expect anyone to identify anything from just photo.  I have a Nikon DSLR and macro photography equipment, so I can take much better photos than the one I attached above.  But I'm new to this forum and don't really know my way around.  Also, I would love to know how to do 3D scans like the beautiful ones you did!

So if you want any fossils identified you can post them here:

And I make those 3D scans through the process of photogrammetry. It can be done completely with free software. It just takes a bit of knowhow. Here's a thread that includes an introduction:
