Hello dear fellow forum members, I have been offered a bundle of bones and teeth from one of the formations subsumed under "kem kem", although the more blackish ones seem to be of a different preservation than the "classic". There are quite some interesting pieces in there, amongst some turtle bones I think. I would be grateful for any hints on ID you can give me. first some of the tentative turtles.

Looking for a little help identifying some small Kem Kem vertebrae. I have some ideas as to what they might be, but I'm sure I'll be corrected. Hopefully the answers will prove useful to anyone else trying to identify Kem Kem verts too! So here's what I think these are: Vert 1: Small theropod, possibly a juvenile spino? (or maybe crocodile) Vert 2: Crocodile Vert 3: Crocodile? Vert 4: Theropod dinosaur Vert 5: Theropod dinosaur (looked a little similar to an Abelisaur vertebra I've come across on the forum before)

A suspicious Spinosaurus claw
FF7_Yuffie posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, thoughts on this Spinosaurus claw, please? The color looks very odd to me--usually, claws I see for sale are more of a sandy color. But then--given the fact there are a lot of faked spino claws out there, I figure I can't really go with what I spot online. Also--the mosmatyched colors--some light bits, some dark bits. Finally--the structure of the claw is very rough. Much rougher than other claws I see online. Also--when I look at the groove, it's very rough and jagged. Not a smooth shape. I would appreciate others thoughts.

Hello all. I picked up a mystery specimen. It's from the Kem Kem (Tegana Formation), ostensibly. It weighs 1.5 pounds. The skull has hollow cavitiies (air sacs?) inside, but I can't tell if they're air sacs; for arteries, or for nerves. They're definitely not mere 'holes'. I spent hours cleaning out pebbles and tiny/flat river-worn rocks and red matrix that filled almost every one of the holes that you see, so almost all of the holes were open pathways when the creature was alive. It was sold as Carcharadontosaur, but with an emphasis that it's not known what bone it is. The bone is solid/heavy, even with the open passages. The only two body parts I could think of are 1) skull fragment, but I have no idea what part. 2) A partial vert: It looks like a neural pathway that runs between a vert and the spinous processes. However, I've not known vert processes that have this shape. Any educated guesses would be deeply appreciated. Please note that the last 'image' is a video; it provides good context for orientation. I can post additional photos if that helps. IMG_2513.MOV

Small theropod claw?
BirdsAreDinosaurs posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi all. This little claw (1.6 cm) from the Kem Kem beds is claimed to be a theropod claw. Is that correct? Is it possible to id it to family level? Out of curiosity, I was also wondering if it is possible to tell apart avian and non-avian theropod claws. If so, how can you tell? Thanks!
-
I got another vert looks decent and different than the other ones i got.

Hello, I was looking at dinosaur teeth listings and this one caught my interest, it looks kinda like a dromeosaurid but also looks kinda like a carcharodontosaurus tooth. It’s from kem kem, Morocco and measures 0.46 inch. I was wondering if anyone could tell me what it is, thanks

Hi All, I acquired this piece of fossilised bone fragment recently and was assured that the specimen was Spinosaurus and came from the Kem Kem group, unfortunately I was not able to gather which formation it was from within the group. Although this piece is fragmentary, its hour glass shape and the thin ridges along each side give me hope that someone would know where on the skeleton this bone is from. I've done some quick research and found that Spinosaurus vertebrae are of similar shape but I am not 100% confident that it is a vert. If anyone has any idea which bone it could be, that would be brilliant (apologies for quality of the side images, my camera had trouble focusing on the thin ridge)

Spinosaurus Tooth, Real or Fake?
micaham posted a topic in Is It Real? How to Recognize Fossil Fabrications
I recently purchased this Spinosaurus tooth from the Kem Kem beds in Morocco, it’s 3 3/8” long and supposedly has no repair or restoration according to seller. Does the tooth show any signs of repair or restoration? Is it entirely real?

Fossils from marocco kem kem
Simonsaz posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, what do you think, can i go "wrong" with these fossils from morocco? Are they real? Many greetings -
Hi all, This tooth is from Tegana fm, Kem Kem. I'm thinking it's a morph 10. The mesial carina seems to extend to the base, although it really thins out and gets dense (so I don't think it's a premax). Any input is appreciated. CH: 35mm CBL: 16mm CBW: 10mm Mesial serration density: 2.2/mm Distal serration density: 2.0/mm

I’m gambling that this is a spinosaur bone, as it is supposed to be, but I really don’t know. Can anyone ID what this bone is, and if it’s spinosaurus or not? It’s apparently from Kem Kem. Thanks so much for any, and all help:)

Hey all, During a discussion about different locations in the Kem Kem, this tooth came up. It always puzzled me, but I figured it was just an odd Carch tooth. But the reaction I got sounded like it was worth taking some better pics of. Any thoughts? Kem Kem is all I've got CH: 26mm CBL: 16mm CBW: 7.75mm Mesial serration density: about 2.75/mm Distal serration density: about 2.75/mm Thank you!!
-
Hey all, While I had my Kem Kem mystery teeth out (i.e., for my post from yesterday), I thought I'd see what you think on this tooth, which I find to be particularly unusual and interesting. Kem Kem is all I've got CH: 14.5mm CBL: 7.3mm CBW: 2.9mm Mesial serration density: about 5/mm Distal serration density: about 3/mm, extremely apically pointed Thank You!

Spinosaurus Jaw Piece with Tooth
ConnorR posted a topic in Is It Real? How to Recognize Fossil Fabrications
I saw this item for sale, said to be a Spinosaurus jaw fragment with an associated tooth glued on. Is it a composite, and does it belong to Spinosaurus?.thumb.jpg.411114bb290b77f5e2bf334dc0a583ca.jpg)

Hi, Unusual looking tooth here. Sold from Kem Kem and dimensions are 20×8×6 mm. It doesn't look like any tooth I have seen from there before. I am wondering if it could be a more unusual type of crocodile than the usual croc teeth we see. Anyone have any ideas?

Hello, some time ago I bought these 3 theropod teeth from Morocco. I suspect they come from the Kem Kem Formation, but I'm not sure because the colors are sometimes unusual. Do any of you have any idea what species or groups of dinosaurs we are dealing with here? I first labeled them as Abelisauridae indet., but I'm not sure if that's true, especially for the first tooth. Thank you in advance. Tooth 1:

Hello fossil lovers, i bought those bones at Sainte-Marie-aux-mines and i need help for identification. All are from Kem Kem. 1 : I think an abelisauroïd (?Noasaurid) cervical but i need confirmation. 2 : no idea about this vert. 3 : distal caudal vert but no idea for the identification. Croc ? Dino ? 4 : Spinosaurid mid-cervical vert but i need to know the exact position

Red Flag on Kem Kem Dinosaur Material
Troodon posted a topic in Is It Real? How to Recognize Fossil Fabrications
Good examples of reconstructed vertebrae can be seen on the Web at hefty prices. In this example the seller properly identifies it just has a theropod and says the repair is "using the filler method " and it's an investment grade fossil. It's impossible to tell what has been done to this vertebra but what is evident is that the processess have been added and covered using the " filler method.. We do not know if the processes belong to the centrum, my guess probably not, or if the front and back are from the same vertebra. All the sand fill tells you how much repair has been done to the specimen. Here the seller is offering an associated pair of tail vertebrae from a Spinosaurus. In my opinion they don't look like theropod vertebra more like croc but I really don't know. Again the excessive sand matrix on the sides is a red flag for problems. Another Spinosaur vertebra being offered. Think I've seen this one before. The processes have been added and we do not know where from in fact the short ones don't even look like processes but peices if bone. The centrum may be Spinosaurs but identifying vertebrae in the Kem Kem without known processes is very problematic. . This is what caudal "tail" vertebrae looks like from a Spinosaurid..thumb.jpg.98654cc3d5155d112e5f1dc6204eeb07.jpg)

How real is this Theropod claw from the Kem Kem?
msantix posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, I have been offered a Kem Kem claw which I think is a theropod hand claw, but when it comes to claws from the Kem Kem, I have little idea on how to spot composites or claws made out of carved bone (or at least, I worry too much about Kem Kem claws no matter how good they seem). Wanted to ask if someone can help me determine if this claw is real, and if so, are there any repairs done on it. Thank you!

Hello everyone, i saw this mid caudal vert from the Kem Kem on a seller website and i directly understand that it can’t pertain to spinosaurus ; so i compared it with caudals from Ouranosaurus and titanosaurs and i see similarities but i need other opinions to be able to decide for the identification. The first image is the vert from the Kem Kem, the secound is caudals of Tambatitanis (a titanosaur) and the third is a caudal from the Venice Ouranosaurus specimen.

Hello ! Info from seller : Spinosaurid neck vertebra from kem kem . What do you think ? Best regards Guns

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.
