Hello, Found an online sale of an indet. Raptor claw, see the link below. edit: it is something that somebody else has for sale and I decided not to purchase it. Found it unfair to have it listed here as potential fake without any clear answer. Therefore I deleted the photo’s, best answer is a link to similar fossils, so thats the informative value of this post.

Hello fellow forum members, some time ago I acquired what I thought of as a theropod ilium from the kem kem . it just crossed my mind that it could be another kind of archosaur alltogether, maybe a crocodylomorph? What do you think? At the moment i can not take more pictures of it easily, but maybe one is enough? Thanks and regards, J

This bone was sold to me a while ago and was described as coming from Deinonychus antirrhopus. A little while later, it was simply put as a chunkasaur due to having no evidence of it being theropod. I recently found that there was a hole running straight through the bone that had been filled in by matrix during fossilization. All of the bone skin is also present asside from the broken ends. I think it may be time to reconsider this specimen. Edit: I couldn't figure out how to link the previous post I made on this.

Found this little guy in the surface float near Glendive, Mt, hell creek formation. I thought it might be a theropod phalange, but a buddy thinks it's champsosaurus. Any thoughts?

Hi all. This bone fragment is advertised as a dinosaurian rib fragment. It is over 4 inches long. Is it possible to say something more about this fragment? Is it indeed dinosaurian, and if so, did it belong to a theropod or a sauropod? And is it a rib? I did a quick online search but could not find a matching cross section myself. Thanks!

Hi all! This is a piece of fossilized bone from the Cloverly Formation of Montana. I thought that the structure of the trabecular bone looked very similar to that of theropod bones but needed a second, third, fourth, or how ever many more opinions. Thanks! (Theropod bone cross section for reference)

Hi all. I recently bought this interesting little tooth from @pachy-pleuro-whatnot-odon. When he first bought it, it was labeled as a Deltadromeus agilis premax tooth. What Deltadromeus' teeth look like, no one knows, but I see why someone would ID this as a premax theropod tooth because of its triangular base and the mesial carina that looks quite theropodian. But to my knowledge, theropod premax teeth have their two carinae located on/towards the distal side, and there is no carina on the midline of the mesial side. What do you think? Is this a premax theropod tooth? Is it even dinosaurian, or could it be something else entirely (perhaps a pterosaur or other reptile)?

Hello, I'm asking about the following bone end. It's said to be from the "Judith River Formation North of Havre, MT". Seller thinks it might be a bird bone since it's hollow but doesn't look like theropod, what do you think? @Troodon confirmed it's not dinosaur and might be turtle, is there enough to tell? And how would one make that distinction?

Hi everyone! I have my eye on a very interesting fossils from the Hell Creek of Powder River County Montana and both the seller and I am not really sure what this is. It appears to be a vertebra of sort with a large bump in the middle. It measures 5.75 x 3.25 x 2.85/2.2 inches for the centrums (14.6 x 8.255 x 7.24/5.588 cm). To me, it looks like two Struthi caudals that were fused together either from an injury or some sort of disease like cancer. It could also be one large pathological vertebra. Do dinosaurs have fused sacral vertebrae? If yes it could be that. Or it could be something else I didn't even think of. Any insight is greatly appreciated as always!

Hi everyone! I acquired this vertebrae a little while ago. I'm reasonably certain it's dinosaur and and would greatly appreciate some help narrowing down the ID. It's from the Hell Creek Formation of Powder River County, Montana. The piece is 5 cm tall, 4.7 cm wide, and 2.9 cm long. The centrums are 4.2 x 3.6 cm and 4.4 x 3.7 cm. The bone is really spongy which is best seen in pic 2, the pores are all 1 to 2 mm so I'm kinda leaning toward Theropod (if that has nothing to do with a Theropod ID please correct me). So what do you all think? Any feedback is greatly appreciated as always!

Hi everyone! I acquired this vertebra as part of a menagerie of kem kem fossils awhile ago and could use some help Identifying it, if that's even possible. I'm leaning toward Theropod indet. but croc wouldn't surprise me if only because I just assume everything Kem Kem is croc until prove otherwise. I don't think it's Spinosaur from comparing it to the pics of the holotype. Maybe someone will see something I don't which narrows the id down further. Digital caliper measurements are 75.51 mm tall, 61.6 and 63.5 mm wide centrums, and 43.84 mm long/thick (not sure which to use to describe this). Any insight is appreciated as always!

Hi everyone! I acquired this Vertebra a few months ago. It's from the Hell Creek of Powder River County, Montana. The seller listed it as Theropod and I was hoping to make sure. It measures 3 cm long, 2.6 cm tall, and 3.2/3.5 cm wide on the centrums. So what do you all think? Any feedback is greatly appreciated as always!

Hi all. This tooth (about 2 cm) is advertised as Rugops and I have seen some similar teeth online with the same id. I am pretty sure that that is not what this is as it does not look Abelisaurid at all, but I have no idea what it could be. Especially the distal edge seems pretty weird to me (like it is a double edge), although these pictures from the seller are not great. The mesial edge does seem to be serrated. Is this even a theropod tooth? Thanks!

Hi everyone! So first and foremost let me say, it's not a composite. Yes I know there is some sediment where the process meets the centrum, yes it is Moroccan, yes 99.9999999% of the time that automatically means funny business but I've looked at the area really carefully and the bone connects there (might try getting rid of some of that matrix at least on one side depending on what it's from). Anyway, I'm on the fence on this one. I was comparing it to a similar thread where a fellow asked about a caudal vertebra from the kem kem which turned out to be croc but was sold as Rebbachisaurus. In the thread some pics were posted of Titanosaur caudals and this looks really similar to that versus the examples of Crocodyliforms that where shown. But before I take that leap I would like a second opinion. The dimensions are 2.25 in. (6 cm) long, 1.85 in. (4.7 cm) tall, and .83 and .75 in. (2.1 and 1.9 cm) wide on its centrum. I also included the pic from that thread of Titanosaur caudal that was posted by Troodon.

Hi everyone! I've gotten ahold of some kem kem phalanges and while I think most are Theropod I still could really use a second opinion to make sure (and potentially a further id like Spinosaur). I say most because while I'm fairly certain the first three are Theropod the last one looks off to me. Kinda reminding me mammal phalanges from deer or something I've seen from Florida. Any insight is greatly appreciated as always!

Hi everyone! How do I differentiate cretaceous hollow bones from Morocco from being Pterosaur or something else like raptor or theropod? Here's a few hollow bones I'm working with right now, if e could provide some insight on differentiating them I'd really appreciate it. I think all but the one in the lower middle is Pterosaur since it has really thick bone walls.

Hi everyone! I've got another hell creek phalange I could use some help on. There's some damage on the front which exposes the inside showing it's hallow, so my first though was theropod, but I don't know for sure. dimensions are about 1.25 x .625 x .55 inches. Any feedback is greatly appreciated as always. Also Happy Thanksgiving!

Hi everyone! I recently acquired some hell creek dino phalanges and could use some help identifying them further if possible. This one was advertised as theropod and I'm thinking it might be Tyrannosaur since it seems to robust to be any of the little guys like the raptors or whatever Richardoestesia and Paronychodon are but I wanted to make sure. measurements are about 1.5 x 1 x 1 inches. Any feedback is appreciated as always!

Seller offer a group of vertebra . seller claim that these group belong to Theropod vertebra from Carter country Montana , hell creek formation . i personally think that it may belong to other reptile or even a croc ? but i am not sure . would like to hear opinion from the community first. thank you

Hi I recently got this tooth. It’s from Alberta Canada but that’s all the information I have on it. It’s 1.5 cm at the longest size with 28 serrations on that side.
