Hello all Yesterday, I could add a few more items to my ever expanding Kem Kem collection. I am very excited with these pieces, but some of them I have a lot of questions by. 1) This weird lungfish toothplate. Currently there are 3 species of lungfish known from the Kem Kem beds. The first and most common species is Neoceratodus africanus, of which the toothplates are described as 'Toothplates with deeply incised ridges'. The second species is Ceratodus humei, described as 'small toothplates with low ornamentation and only four low ridges' Third species is Arganodus tiguidensis, described as 'small toothplates with a characteristic radiating pattern of ridges' I have the first two species, and have only rarely seen Arganodus popping up in the Kem Kem beds. But now I got this tooth: This tooth doesn't match any of the descriptions of the three regular species of lungfish. The only match I could find was Lupaceratodus useviaensis, a extinct lungfish species from the Cretaceous Galula formation in Tanzania. My tooth is a lot bigger however, standing at 4.5 cm and having 8 ridges instead of the 6 of the Tanzanian specimen. So what could this one be? I'm thinking it's most likely a new species or a species new to the location. I would be happy to hear the opinions of the people on here. 2: Double barbed Onchopristis barbs A while ago I made a topic regarding one of these barbs. The general consensus then was that it was a rare pathology, but now I have multiple specimens with double barbs all found at the same location. They are all in better quality then my first specimen and with the exception of some small repairs, no work has been done on them. Would you all still think this is a pathology? How large is the chance that multiple of these would be found in the same spot? All of these are in the normal size range of Onchopristis barbs. Link to previous topic: 3) This is probably a piece of chunkosaurus. Not sure if it's still in any way recognizable. It was sold as Coelacanth skull bone, but I'm more interested in the weird patterns on the bone. I've been searching a long time for traces of invertebrates from the Kem Kem beds (they don't really fossilize unfortunatly) and I think this time I might have found some. Could these tracks (marked in red) be tunnels of some kind of burrowing creature? If anyone recognizes the weird texture on this piece of bone that would be really helpfull.

Hello all I recently bought a tooth from the Kem Kem beds that clearly belongs to the genus Onchopristis. The weird thing about the tooth is that it has two hooks instead of just one. I know the species Onchopristis dunkeli has two (or more) hooks, but I don't find any official rapports metioning them in the Kem Kem beds. The tooth has yet to arrive, but I already wanted to ask the question. What do you think? Is there a chance O. dunkeli occurs in the Kem Kem beds or would it just be a pathological example. I have been searching a long time for a specimen like this. The tooth has not yet arrived so sorry, no photo's yet. @LordTrilobite, @Haravex Greetings Thijs

Spinosaurid tooth acetone soak: worth the risk...
BirdsAreDinosaurs posted a topic in Fossil Preparation
...or just a very bad idea? This is a partial Spinosaurid tooth. The other side of the tooth is completely missing. Areas of the tooth are covered with what I believe is glue mixed with sand or matrix. I really don't like the look of this Moroccon method to "improve" teeth. I already tried to rub the glue/sand mixture off with a acetone covered rag and the tooth looks a bit better than before (although the tip fell off and I had to reattach it with some superglue). Now I am thinking about soaking the tooth in acetone to remove all this glue/ sand mixture and then put it back together with just glue. Could this result in the whole tooth falling apart, as it might be consolidated with glue? What would you do, giving the fact that the tooth was very inexpensive but I still do not like the idea of destroying it? Thanks!

Authentic Spinosaurus claw?
Mrhenky3 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone, I came across this Spinosaurus claw. I was wondering if this claw is genuine. It looks to me like it consist of multiple fragments added together. Thanks in advance. Location: Kem Kem beds Size: 13 cm

Another rooted spino tooth
Nanotyrannus35 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I found this spinosaurus tooth online. It seems to have a mostly complete root. However, it does look like it has been repaired, and there might be some restoration, but I can't tell. Thanks for any help. The tooth also appears to have some striations along the carina.

Another Kem Kem tooth (17 mm). Pretty sure it is Abelisaurid, but it does have some noticable differences with my other Abelisaurid teeth. It is less compressed and one side of the tooth (the lingual?) is pretty flat, while the other side is not. Am I right to assume these are probably just positional differences? Could this be a more anterior tooth? Thanks!
-
Hi all! I received this tooth (5 cm) in my mailbox today. My best guess is an anterior Carcharodontosaurid tooth, but I am not entirely sure. It is pretty fat and the distal carina is displaced. What do you think? Thanks!
-
I'm thinking of buying this tooth. It was listed as "raptor, but looks like theropod indet. to me. Or, it might be one of those teeth that actually are dromaeosaur. What do you guys think? It's about a half inch or 1.2 cm.

Hey, So I was just reading about radioactivity in fossils and I'm paranoid. I just got a smallish (8 inches, by 6 inches matrix) from the Moroccan phosphate beds. How likely is it to be dangerous? And how best should I store it?
-
Wondering if this is a Sauropod partial scapula from the Kem Kem. It is 28cm long and by the looks of it, I do believe it is from a scapula but not sure if it is indeed from a Sauropod or a crocodyliform. Thanks.

Strange Spinosaurus fossil.
ConnorR posted a topic in Is It Real? How to Recognize Fossil Fabrications
First off, this is my first time posting on the forum. So hello everyone! I just got my hands on some Spinosaurus fossils, allegedly from the Kem Kem beds. Both are from a seller in Arizona. One of them is a hand claw, as seen below. I'm not 100% sure that it's from a Spinosaurus, so I hope someone can tell me. But it seems very real. The other specimen, though, has some bizarre properties. I thought it might be fake. But after doing some tests on my own, I'm only more confused. These are the vertebrae that I bought. The first thing you'll notice is that they appear crushed, flattened and distorted. In the last photo, you can see some tool marks on the back of the second vertebra. But I noticed some strange things. Firstly, it makes a hollow-ish sound when tapped. Not the matrix, just the bone. Secondly, the bone has a faint odor that's hard to describe. I did a scratch test with a small pick to see what was up, and it's VERY soft. It's somewhere between 2 and 3 on the Mohs scale. I can't scratch it with my fingernails, but I can scratch it with limestone, producing a fine white powder. I scratched a little deeper to see if the smell was because of paint, but found that it's the same deeper down. The matrix is also fairly soft. I can scrape it easily with a steel tool. Confused, I did an acid test with vinegar to see if maybe it's carbonate or something. It didn't react, but I found that the bone absorbs liquids very slowly, even though it's not porous to the naked eye. And by slow, I mean it takes 20-30 seconds to absorb a drop of liquid. Another strange thing is the coloration. It's mostly white, with orange in some parts. But in the following image, you can see that some of the cracks have a reddish color. Now notice that there are small fossil fish teeth and vertebrae in the matrix. I wanted to see if they had the same properties as the large bones. If they don't, then maybe that would indicate that the Spinosaurus bones are fake. Maybe the matrix is made of crushed rock that just happened to have fish fossils in it? So I did a scratch test on the fish vertebra in the following image to see how hard it was. I found that it has exactly the same properties as the larger bones. It's the same color, it has the same hardness, and it produces the same fine white powder when scratched. The fish vertebra is only 3mm long, and there are many smaller fossil fragments throughout, all with the same strange properties as the large bones. At this point, I'm convinced that it's real, and that it's probably Spinosaurus. But beyond that, everything about this specimen is weird. Does anyone have any ideas about what the deal is here? How could this have formed naturally? What mineral(s) is it made out of? Or if you think it is fake, how do you think it was made? Either way, do you think $500 was a good deal?

Are there any raptors in the Kem Kem formation? I've seen that I think just about all of the teeth listed as raptor are actually abelisaur. On Wikipedia, it said that Deltadromeus isn't a raptor. I'm confused because I had thought that it was.

Hi guys I've known this piece for like 10 years and the owner finally sold it to me. The size is 10,5 cm and the only original tooth is the middle one... Need some help in the id to understand if it's crocodilian or spino indet.

Hi guys, I have this croc tooth from the Kem Kem beds and I haven’t been able to identify it, would anyone be able to help? Thanks
-
Hi, I'm interested in this fossil that is listed as a Theropod Ilium bone from the Kem Kem (21cm in length). I wanted to ask if there are enough diagnostic features to identify it as belonging to a theropod or does it resemble something from a crocodyliform instead? Thanks!

3.93in Carcharodontosaurus tooth from the Kem Kem Beds
DardS8Br posted a topic in Member Collections
I have this beautiful 3.93in Carcharodontosaurus tooth from the Kem Kem Beds. There’s some very minor restoration done to the tooth, with just some crack filling to two very small cracks in blade. The tip and serrations are completely intact however, which is absolutely incredible
-
Hi everyone! I'm helping a buddy go through and identify a ton of Moroccan stuff he acquired several years ago. There were two large ribs, the first is 10 inches (straight line) an the main part is .75 inches wide. the second is 5.5 inches (straight line) and 1.25 inches wide. I'm fairly certain these are Dinosaur or crocodile, leaning toward dinosaur but I'm not certain which type. Any feedback is greatly appreciated as always!

Rooted Spinosaur(us) tooth from Kem Kem Beds. Measures 5.55in in length -
Hey all, I acquired a large box of bones from the Kem Kem beds of Morocco. I don’t have information on them besides that. I suspect a large number of these are crocodilian, but there’s an assortment of other things as well. All told there’s probably 60-90 bones in the box, so I’m going to avoid putting too many in a post. All measurements are in inches. set A: set B: set C: set D: set E: Thanks all for any help!

Hi guys! I found this vertebra on sale, probably caudal, can be spino? There are only these pictures… Thanks!

Any thoughts on what Family of theropod this tooth might represent? It comes from a trusted source and was collected from the Kem Kem near Taouz, Morocco. Thank you for your comments on my previous submission, especially Troodon.

Kem Kem tooth repaired?
Adam86cucv posted a topic in Is It Real? How to Recognize Fossil Fabrications
I was curious if this tooth has been repaired or anything weird. Seems like it might have been broken and glued back together. I'm a bit curious about the shiney look and dark speckles on it. Does it seem like they put a coating on it and the speckles are matrix or miscellaneous 'dirt'? For the price I am offered it at I know it's not going to be perfect. Just wanted to see if anyone saw any red flags or weirdness.

Lepidotes Fish in Kem Kem?
Seguidora-de-Isis posted a topic in Is It Real? How to Recognize Fossil Fabrications
Good morning to everyone at TFF! What exactly is this? According to the seller, this belongs to a Lepidotes pankowskii (South Taouz, Errachidia Province, South Morocco - Formation Ifezouane, Red Sandstone Beds, KemKem Basin - Upper Cretaceous, Cenomanian stage - ~96 Million Years) . It's real? Is there scientific information on this? Any and all information will be extremely useful to assist me. I thank everyone! @Troodon @LordTrilobite @Tidgy's Dad @Haravex @hxmendoza
