  1. Tooth or claw kem kem

    Hello together, there is a type of fossil from kem kem I have seen several times now under different descriptions in the net: It is either called a pterosaur wing claw, or an undescribed pharyngeal fish tooth. At least to my eye they look like the same structure. The number of specimens lets me think its rather fish than pterosaur, but I´d like to hear your opinions please. Here is an example: Thanks, J
  2. as a connoisseur of Pterosaurs, I wanted to ask the Community here to show me it's pterosaur fossils from the Kem Kem Formation. After seeing a rare Tapejarid Premaxilla recently get sold on a Fossil Dealing site (labeled incorrectly as Alanqa), I wondered what treasures could be present in Private Collections in this Community. Teeth are just as welcome as Bones are.
  3. My Oddball Kem Kem Theropod Teeth

    I know specimens from the Kem Kem are some of the most common things found on the market, but with so much undescribed material, it's a favourite location of mine for finding those fossils that are just a bit odd and often overlooked. So here are some of my theropod teeth from the locality to date, that don't quite fit the usual Spinosaurid & Carcharodontosaurid profiles: To start with, a theropod indet. tooth with a very unusual profile, and unique (for the locality) mesial carina that ends naturally above the midline.
  4. Quite a while ago, I made a post talking about Kem Kem Pterosaurs, well since then I got more information, and new Information has been published. I specifically want to talk about Teeth. Now, the only toothed Pterosaurs we are aware off in Kem Kem are Ornithocheiraens, the clade that includes Ornithocheirids (not in all Versions though), Targaryendraconids, Cimoliopterids, Anhanguerids and Hamipterids. All of these besides Hamipterids and Cimoliopterids are possibly present in Kem Kem. So in my last post I claimed that the Teeth you can find should be labelled as Coloborhynchinae indet. based on the fact that Sirrocopteryx, and Coloborhynchus fluviferox are the only known Ornithicheiraens from Kem Kem, this was wrong. There are 5, or possibly 6 Taxa of Ornithocheiraen present in the Kem Kem Beds, I can only go into detail with 4. Sirrocopteryx: Now Sirrocopteryx is an interesting case, I have heard claims of it being an Anhanguerid, but as of now, I cant confidently say this to be true, so I will stay with the identification of it being a Coloborhynchine Ornithocheirid. Now, what Ornithocheirids have Teeth we can reference? Ferrodraco and Mythunga. (Image 1 in order) We can see roughly triangular very robust teeth in Mythunga, or rather long conical teeth that are still very robust. Image 2 is a Pterosaur Tooth which was sold on FossilEra, and it may most likely reflect Sirrocopteryx, but.... Coloborhynchus fluviferox: This is another Coloborhynchine from the Kem Kem Beds, it also is the largest Ornithocheiraen in Kem Kem, due to it's existence it's probably better to identify your Teeth of this Morphotype as Coloborhynchinae indet. Anhangueridae: Wellnhofer and Buffetaut, 1999 describe a very interesting Pterosaur tooth, "The teeth of morphotype IV are very ro- bust, large and recurved. In cross-section the teeth are rounded lingually, but flattened labially. A carina is de- veloped only along the posterior edge. The enamel pat- tern varies, but, in general, appears to be similar to the pattern of the other morphotypes. The surface of the enamel is smooth. The flattened labial surface of the den- tine is slightly wrinkled. The rounded surface of the lingual side is sculptured by fine, parallel, longitudinal striae and wrinkles. The length of the teeth preserved ranges from 28 to 39 mm." (Image 3) Wellnhofer claims these Teeth could be tentatively reffered to Anhanguera, but Anhangueridae indet. is preffered here. Targaryendraconidae: In (Pêgas et al. 2019) the Taxon Targaryendraco got described, which formed the basis of a new pterosaur family, Targaryendraconidae, in the same paper they describe "[...] are several isolated teeth that are elongate, striated, slightly recurved and elliptical in cross-section; including specimens from the Kem-Kem Beds, Cenomanian of Morocco" (Image 4) This is it, till the other new Taxa get published I cant say anything more, but I hope this post was useful to some.

  5. Carcharodontosaurid foot claw?

    Hi, I saw this large 8.9cm (3.5 inch) Kem Kem claw for sale. It is labelled as a Carcharodontosaurus (or Carcharodontosaurid) foot claw. I wanted to ask if the identification looks likely - i don't believe it is Spinosaurid and not sure of other large theropods the claw could be from. I should also ask if it looks genuine - the seller states that there are a few breaks but no restoration done on it. Thank you.
  6. Kem Kem bones thread

    Hello everybody, this is all my new bones from morocco, i need many precision on it, if you could. I know they are few publication of Kem Kem but you coule maybe help me. Firstly, i have those two vert, i don’t have idea for the identification. The smallest is clearly a reconstruction, perhaps with a piece of rib.
  7. Serrated Spinosaurid Tooth - Kem Kem

    I've spoken to Troodon a little elsewhere on the forum regarding this serrated Spino tooth; my main question is regarding the root - can anyone verify whether the root looks to originally be from this tooth? It's obviously been reattached, but sand has been used to fill a gap between the crown & root, which makes me wonder a little. For anyone wanting wider details around this little oddball: • Length approx 48mm long (including the root) • Very slightly recurved • Mesial carina naturally terminates at the midline • Denticles appear to be 2/mm on both carinae • Veiny enamel texture • Extremely minor fluting on one side The Interesting Features: Mesial Margin: Distal Margin: Enamel Texture: Apologies for the godawful photos. (I definitely need to get a better microscope for this stuff!)
  8. Help: Kem Kem Sauropod Tooth ID

    Hi all, I was wondering if I could get an ID for this tooth. I think it is Rebbachisauruid. It is 4.9 cm long and from the Kem Kem beds of Morocco. Thanks for any help.
  9. Help: Kem Kem Theropod Tooth ID

    Hi all, I was wondering if I could get an ID for this tooth. It is 2.3 cm long and from the Kem Kem beds of Morocco. I understand that Kem Kem theropod teeth are difficult to identify, but I was curious if it could be narrowed down to the family level. Does this tooth resemble what Deltadromeus teeth are speculated to look like? Or is it something else (Carcharodontosaurid?). Thanks for any help.
  10. Fossil Bone?

    Hi All, I'm wondering if you could help me identify this item? I think it's a fossil bone, but I just don't know. I found it lying on the surface where I was camped for the night by the Kem Kem beds. The reason we were camped was to visit the Spinosaurus dig site that was featured in the National Geographic Documentary, Bigger than T. Rex. I can provide the long and lat, for the exact location. The surface it was on was rock strewn, so it was a chance find amidst many rocks. About 8-10 metres from a dry stream edge, not an obvious exposure or deposit from running water. The item had no part of it buried. A link to the full resolution version of images is here, I'll leave the link active for 6 months. https://1drv.ms/u/s!AutS1HGsNzVXi-8IRNetXsI3rwZA4Q?e=C3cqMg My feeling is that if it is a bone, that it may be spinal, with the hole through it as a major conduit for a nerve, or possibly a blood vessel. But really I have no idea, and that's why I'm posting to gain your expertise! Many thanks for your time. Phil
  11. Are there any papers/articles on Enchodus being in the Kem Kem formation? Also does anyone have any specimens they'd like to show off here because I read here that some people have specimens of it, and it just hasn't been described.
  12. Hi all, I have another fossil here for your inspection please. It seems to be a Spinosaurid partial neural spine but I cannot be sure. @Troodon @LordTrilobite

  14. Kem Kem Leptostyrax macrorhiza

    From the album Cretaceous Shark Teeth

    Very rare Leptostyrax from the Kem Kem beds of Morocco. Lower Upper-Cenomanian in age.
  15. Hello, I have purchased this interesting fossil tooth from Kem Kem Beds, but I don´t know about the ID, it looks like Spinosaur or fish, but I´m not sure. Can you help me with the ID? The tooth is 1.1 inch (2,8cm) in lenght. Best regards!
  16. Morrocco theropod tooth

    Would like to get some opinions on this kem kem tooth. It's just under 1.5", would be a hair longer but the tip is missing (faked with matrix). There are 4-5 serrations per mm on the mesial edge and about 2-3 serrations per mm on the distal edge. Opinions?
  17. Abelisaur teeth

    I was looking at different teeth for sale, and came upon 6 teeth listed as abelisaur teeth from the Kem Kem area of Morocco. I know that it’s hard to Id the teeth from this area, and I’m not looking for an exact id. I was wondering if any of the teeth looked like typical abelisaur teeth, or if some are likely something else. I noticed that 4 of them looked pretty similar, and the other group of 2 looked different from the 4, but similar to each other.
  18. Dino or croc vert

    Hello, i bought this vert today, the seller say that is spino but i need à confirmation. It clarly come from the Kem Kem and it’s realy big
  19. Spino caudal vert ?

    Hello everybody, i’m new on this forum. I bought this vert in south morocco (the kem kem). The seller told me that is a spino vert but the spine seems too long and weird. I need your opinion.
  20. Two teeth from the Kem Kem Beds

    I also found these two teeth at our local fair. I bought them despite of the lack of information privided because the spinosaurid tooth (if it is spinosaurid and not mosasaur) was pretty cheap for its size and the other tooth which was labeled "Rebbachisaurus garasbae" had an unusal shape in contrast to all the other material from Kem Kem that is available here. The seller only provided the information that both teeth are from the Kem Kem Beds of Morocco. This is the tooth that was labeled as Spinosaurus aegyptiacus. But from my previous tooth I know that one cannot differentiate between S. aegyptiacus and Sigilmassasaurus so that it should be labeled as "Spinosaurus indet.". Is this correct?
  21. Another Moroccan Dromaeosaurid-like Tooth

    So I've just added another new theropod tooth to the collection from the Kem Kem. I'm going to go out on a limb and say it's another contender for a potential dromaeosaurid tooth? • Very laterally compressed • "Pinched" to small degree at base • Mesial carina terminates well above the base • Slight twist to mesial carina • Mesial serration count (midline): 6 or 7 per 1mm • Distal serration count (midline): 3 or 4 per 1mm There are also interdental succuli present between distal denticles; not something I've particularly noticed on other dromaeosaurids, so I'm not sure if that has any impact on tentative ID? Lingual side?: Lateral side?: Cross section: Mesial face: Distal face: Pinch at base: Close-ups:
  22. Mystery Theropod Tooth - Kem Kem

    I've been browsing online, and come across this tooth. It's listed as Carch, but the serrations look completely wrong to me. The profile of the tooth doesn't particularly scream Carcharodontosaurid or Abelisaurid (though the distal margin does look quite straight) as far as I can judge. Any ideas, anyone? These are the best photos provided... Mesial margin: Distal margin: Distal denticles:
  23. I saw this on the internet and it says its from the kem kem beds with high probability to being sauropod. But as many of you have suggested in other posts its not easy to ID a bone fragment accurately So can anyone help me see if its a sauropod,theropod or croc?Thanks
  24. Kem Kem ribs ID

    Just got some small rib sections and another bone, the ribs don't look like crocodile, I know it can be difficult to give an I'd on parts of bone but was wondering if it could be mosasaur or maybe land based? Bones are from the Kem Kem beds
  25. Unidentified fish scale from Kem Kem

    Hello, On the internet I found and bought this fossil fish scale from the Kem Kem formation. Unfortunately, I do not know which fish she comes from, as she looks different than any other fish scales from Kem Kem that I know. A box on the sheet is 5x5mm, the scale is ca. 1,7cm long. I hope you can help me with that. Thank you in advance, Jesco
