Hello, Can somebody help me ID this pterosaur tooth? The seller says it was found in the Kem Kem basin in Morocco. The tooth is about 1 1/2 inches long.

From the album: WhodamanHD's Fossil collection.
Mosasaur tooth originally in sandstone matrix, I picked it out. Bought from a store in the northeast. I assume Moroccan, species unknown. The matrix had some other fossils in it in another photo. -
Rebbachisaurus tooth?
Seguidora-de-Isis posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello! Good Night to everyone who participates in my favorite Forum! I present to you the newest member of my collection... It was discovered in Kem Kem, Morocco. Very good condition, although there are natural cracks in the enamel these do not appear to have been glued or restored. But I do not think it's a Rebbachisaurus tooth... What do you think? Thank you all! -
A couple of days ago I bought a couple of dozen pieces of random Kem Kem material (I suppose you'd call it the junk that couldn't be sold individually). I know that Kem Kem is a bit mysterious, and that it can be difficult or impossible to identify random bits of bone even to the type of bone, let alone the specific animal. But what that said, that's exactly what I'm hoping someone can do I could identify quite a lot of the pieces, such as sawfish teeth, a piece of shark fin spine, and some fish verts. But most of it is just a mystery. Can anyone help with these bits? This first bone is hollow. Does this mean anything, in this context? The second has a characteristic shape, and I was wondering if that meant it could be narrowed down to the type of bone? The third is just a very robust bone. I don't know if anything can be gleamed from it. Finally, this looks like some sort of scale. Fish? Thanks very much in advance.

I'm trying to unravel a Kem Kem turtle mystery at the moment, but in the meantime, I have these two verts that I find myself unable to ID. Which is annoying, because I thought I'd be better able to do so, using the resources of this forum. The first, I suspect to be some kind of croc, but I don't know enough to be sure. I think it's all original - there are several repaired breaks, but I strongly suspect that they are all original bits. I have searched all over, but can't see anything that looks 100% like it, particularly in terms of the neural arch going straight up like that. Please can anyone ID it? It's 6 inches tall, 3.5 inches wide. The second one is pretty big, 6 inches long. I was hoping this would prove to be theropod, but there are no processes evident to help with ID. Thanks

Hi there, I bought this nice dinosaur bone from the Kem Kem basin in Morocco. Just wondering if a rough ID is possible? The seller said it looked like a rib bone but wasn't sure. Is it a theropod or crocodylomorph? It's had some repairs done to it; few gaps filled here and there. All suggestions are much appreciated. Thank you!

I've been going through some Kem Kem material and trying to identify some of it, which I know is difficult even for someone that knows what they're doing. I don't, at all, but I am reasonably confident on a few bits - I wondered if anyone would be kind enough to give their opinions on my tentative IDs? 1. First of all, and definitely very tentatively, I was hoping that this was pterosaur. Wishful thinking? It's hollow and splits off in two directions at the end. 2. Secondly, this tooth - I'm daring to dream that it might be... sauropod? It only has a tiny bit of enamel left on it, but I'm going by the heavily blunted shape. Knowing me, it's probably a very poor Spinosaurus. 3 - Fish jaw #1 - I'm not at all sure about this, but it has a row of little 'post holes' that I assumed might be for teeth. But I have no idea. Has all sorts of suggestive shapes and ridges. 4. Fish Jaw #2 - this must be a fish jaw, but can anyone suggest what type of fish? 5 - Mystery tooth - at first I thought this was a scrap of bone, but upon closer examination it is clearly a tooth. The shape seems odd to me, it's very triangular, but I have very little experience with teeth to be fair. One end is very, very slightly (a couple of mm) smaller than the other, but there is no visible curvature on any edge. It needs prepping since it's still covered in matrix on every side, but I was wondering if the triangular shape was suggestive of anything. You can just make out the row of serrations on the photo below, along the top, so it must be theropod. 6. A small limb bone from a theropod maybe? The bone is hollow and oval. Needs more prep really, when my workshop is back in action. 7. Crocodile scute. I know that this is some kind of armour, but where were these plates positioned? Down the back? And were they just below the skin? Took a lot of prep to get it this far! Sorry, I didn't set out to post so many bits. Any conformation/refutation/information appreciated. Paul

The newest addition to our dinosaur fossil collection from the Kem Kem Beds in Morocco, a rooted Spinosaurid tooth. It is 6 inches in length, and really shows the strength and size of this animal. There is some cool feed wear on the tip as well. This one is for my 7 year old son, and will be in his Easter basket on Sunday morning. Spinosaurus is is favorite dinosaur, and he's going to go bananas! Can't wait to see the look on his face! .

Tooth of a Pterosaur.

Hey guys and gals, would love an opinion on this tooth I found online. I think I am seeing a repair to the tip, but other than that it almost looks TOO perfect to me. Thoughts? Especially @Troodon and @Susan from PA

About two weeks ago I bought this bunch of Kem Kem chunkosaur pieces in the hope that something interesting might be in there among the nondiscript bone fragments. There were some things that were identifiable. But this one piece completely baffled me when I looked at it more closely. I hadn't noticed it at first because it still had a bunch of matrix on it. But I soon saw some weird square shapes. These remind me of of the shapes some reptiles have under their scales on their skull. The bone piece already had a weird straight shape with a hollow in the middle. At first I assumed the hollow on the inside of the bone that was just exposed due to breakage. But I then cleaned it some more and a pattern emerged on the inside of the fold that I can only describe as a toothplate. I'm almost positive this must be some kind of jaw piece with a strange tooth plate. I know Kem Kem is still very much a mystery. But I've never seen anything quite this thoroughly bizarre before. Has anyone ever seen anything similar to this? Side with the "toothplate" visible as well as clear square shapes on the outside of the bone. It's still not completely clean, but the toothplate seems to extend futher into the fold. Flat outside edge. The square shapes end in half circles on this side. The other side of the edge also has similar patterns but on a different scale and not as clear. Other side with more subtle square shapes on a smaller scale. Both broken sides to show the cross section. It's also slightly asymmetrical.

Hi guys, I am really doubting about these two teeth. I bought them as pterosaur, but I really think the left one is an infant Spinosaur (it has corrugations on te tooth), the right one is anyway Pterosaur I think. What is you guess?
-
Nearly finished this item, it did not survive the journey well (not packed by me) and was in numerous pieces. Turned out ok though IMO once stabilised and re-joined. Can you see the gastrolith? Nigel

What is the "anceps" in Prognathodon anceps? Is that the species name? I'm having a hard time finding anything online to explain other than some dealers selling some teeth on various sites. Sorry for my ignorance and thanks!

Auction Spinosaurus Jaw
BadlandTraveller posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi Everyone, I've been shopping for a Spinosaurus Jaw for a little bit and saw this guy online. I did search previous posts on Spino jaw ID but I thought I'd open it up to the group as I was unable to determine if it was croc or spino. Thank you.thumb.jpg.84cd6a9666c21027af34bcbc42e1c532.jpg)

So I came across this vertebra on the internet. It's labeled as a large Spinosaurus vertebra. I don't think it's that due to it being very flat. But one thing caught my attention. One side seems to have a lot of air sacks. So my first thought was that it could possibly be a Sauropod vertebra. What do you guys think?

Looks somehow similar, but is not related to needlefish. Rhynchodercetis means "beaked throat whale" References: Martill, D., Ibrahim, N. Brito, P., Baider, L., Zhouri, S..

Comments on Dino Items in Auction
Troodon posted a topic in Is It Real? How to Recognize Fossil Fabrications
Proper identification of Dinosaur Material with European auctions is typical of what you find in Domestic one. Here are comments on a few items being offered since a number of our members are attracted by their offerings. Here is a beautiful rooted Tyrannosaur tooth being offered. The description suggest it might be a Tyrannosaurus rex but states it there is no label. The preservation looks like a Tarbosaurus from Mongolia, not T rex. The other observation I would make is that there appears to be significant restoration to the lower half of the root which is not stated. A number of T rex teeth being offered appear to look more like Nanotyrannus not T rex. Use caution on all teeth. All of the teeth offered as Albertosaurus should be labeled has Tyrannosaurid indet. e A Triceratops horridus ungual being offered looks more like the hadrosaur Edmontosaurus. Numerous lots of items being offered are Triceratops horridus should be better identified has either Triceratops sp. or Ceratopsian indet. Quite a bit Moroccan Kem Kem material being offered, caution with all of it. The larger teeth are accurate but smaller Abelisaurid teeth are misidentified has Deltadromeus or Rugops. This Deltadromeus raptor claw may not even be Dinosaurian difficult to make that call. Isolated toe bones are hard to ID to a species especially . This one may be has listed Spinosaurus but a better call would be Theropod indet. Just exercise caution and if there are items you are interested in feel free to post them here for our input.

Vertebral process of Sigilmassasaurus. This is likely a mid cervical vertebra. It also bears close resemblance to the Spinosaurus maroccanus holotype which I consider to be synonymous with Sigilmassasaurus brevicollis.

I've had this tiny piece of bone from the Kem Kem beds in Morocco for a while. And initially I hadn't looked at it in detail and kinda dismissed it as a random piece of fish. On a whim I re-examined this piece under the microscope and noticed it has an articular surface on it that has a weird shape. The shape is so weird, the only thing it reminds me of is the jaw joint on the quadrate. So could it be a piece of skull? And then I noticed it has spongy structure on the inside of the bone. So that reminds me of reptile bones. I've compared it to most of the known types of reptiles from Kem Kem. It does seem to vaguely resemble many of the quadrates of different animals but it's still quite distinct. The closest match I could find were the quadrates of turtles. But then I compared it to three known turtles from Kem Kem and those also don't seem to match exactly. Only the general shape seems similar. https://en.wikipedia.org/wiki/Kem_Kem_Beds I did find some good reference though. Two of the same genus but different species: http://digimorph.org/specimens/Galianemys_whitei/ http://digimorph.org/specimens/Hamadachelys_escuilliei/ Paper that includes two of the Kem Kem turtles: http://digitallibrary.amnh.org/handle/2246/5824 I can't seem to find a good match. Does anyone have any ideas? Ventral? Dorsal? Anterior? Anterodorsal? Posterior?
