  1. Kem Kem beds: dinosaur toe bone?

    Hello all Some time ago I got this bone from the Moroccan Kem Kem beds (Cenomanian in age). It looks like it's deformed during fossilisation (or afterwards). It would be 10 cm long, about 3,5 cm wide and 3 cm high in it's original state. So is this in fact a dinosaur toe bone? If so what family could it be? Or am I completely mistaken and is this something entirely different.
  2. small kem kem jaw sections

    I'm quite interested in these small pieces. Sold as small reptile jaws from Kem Kem. The longer one is approximately 4cm, the shorter one is around 2cm. So very small jaws. I'm guessing, given the circular tooth sockets, they are from a small or juvenile species of crocodile? Or could they be from a type of lizard? If anyone can take a quick look, that would be great. I'm guessing they are much too small to get an actual species, but would be nice to know if croc or lizard. Thanks
  3. Help ID croc tooth from Kem Kem

    Hi everyone, I got these tooth from an auction. The only information I have that they are all from Kem Kem Basin and the number 1 as the seller description that Elosuchus sp. ~4cm but actually I'm not sure it label. So if anyone has any ideas of all of them that would be great. Thank for reading!
  4. Kem Kem crocodile jaw

    I won this a week or so ago on an auction. It was sold as undescribed pseudosuchia with a description "dog-faced crocodile". 2.33 inches long. From Ifzounane Formation, Kem Kem Basin. Description says it has been analyzed by experts as a new species. Nothing comes up for "dog-faced crocodile" other than this very fossil. Anyway, I meant to post it up here to get looked at but forgot about it until now. Anyway, here's some photos. If anyone has any ideas what it could be from, that be great It also came with a pair of nifty X-Ray type photos.
  5. Kem Kem pterosaur teeth: any clarity?

    I recently purchased the two Kem Kem pterosaur teeth shown below. The seller identified both as "Siroccopteryx (Coloborhynchus) moroccensis", but I've learned by now that sellers will apply any remotely plausible name to help a fossil sell, even if it isn't scientifically justified. I read the pinned page on Kem Kem pterosaur ID, but am still confused about the exact species/genus ID of my teeth (if ID to that level is even possible for isolated Kem Kem pterosaur teeth). So: 1. Are these, in fact, both pterosaur teeth? My understanding is that pterosaur teeth are hollow and have enamel only on the tips. Both these teeth are hollow, and while the larger is missing enamel the smaller indeed has enamel only on its tip. These also do resemble photos of other Kem Kem pterosaur teeth online, though the larger is a bit unusual (though it matches the tooth in Figure 7b of the pinned article). 2. Do any of the experts here feel comfortable stating a genus for either tooth? Or do I just need to abandon my hope for ID of isolated reptile teeth to that taxonomic level? Any help is appreciated!
  6. Hi, Just wanted to check if this fish skull bone from the Kem Kem in Morocco is real or not? I think it is, but I wanted to get opinions about this fossil. Seller states that there is no restoration only a few glued fractures. It is 12cm in length. Thank you.
  7. Spinosaurus quadrate bone?

    Can anyone tell me if this is a spinosaurus quadrate bone? It is apparently from Kem Kem. I think it looks pretty quadratey, just going by a number that I’ve seen in pictures. I JUST purchased/won it, but havent paid yet, so I was hoping I could get opinions ASAP, so I can either pay right away, or discuss cancelling the purchase if it’s not what it’s supposed to be. Normally I would have asked for help on here BEFORE purchasing, but it was a last moment situation, so i barely even had time to think, let alone post on here about it. Any help is greatly appreciated, as always!!! oh yeah, also, what’s that odd thing attached to the side of the upper part, thats even a different color? I’m guessing it’s part of the fossil, just....I don’t even know! I have no idea what would make it so weird and different from the rest.
  8. A pair of skull pieces? Kem kem

    First says, cranial bone with a clear forage (if that means anything?) Seller says probably theropod. 9.45 inch Second, says quadrate skull piece, probable theropod- likely spinosaur. 4.57 inch. Both Kem Kem. Not associated by the way. Anyone able to take a look?
  9. Vertebrae from Kem Kem

    ... as mentioned in my other post, from the Kem Kem is this vertebrae. And before I start cleaning it up it would be great to get some comments from the vert experts here - maybe crocodile?
  10. Spinosaurus jaw?

    It is been sold here--seller gave me permission to post it on the ID thread for a second look. So, if anyone can give me your thoughts, that would be great! It is spinosaurus, from Kem Kem Basin.
  11. Kem Kem teeth

    Hi, just working and prep on a box full of Kem Kem material incl. some verts (will post later) and some nice teeth. below are two teeth which I would now label up as Spinosaurid indet. - can you guys confirm this? 1. a small one 2.3cm long:
  12. Peruvian ammonites and kem kem tooth

    Hi guys I would appreciate your help identifying these fossils I’m sorry I don’t know any more than what is in the title i was thinking the tooth was maybe croc but which one I’m not sure
  13. Hi, Saw this fossil for sale and the seller believes it might be a partial vertebra from a Sauropod. It is from the Kem Kem in Morocco and I am not sure if there are enough diagnostic features to be sure, anyone have an idea as to what it might be?. It is 22cm in length. Thanks.
  14. Abelisaur?

    listed as possible Abelisaur but at just over an inch, seems to big. Most I see for sale are quite small. Anyone have any thoughts?
  15. Carcharodontosaurid Tooth Position

    I have had this carcharodontosaurid tooth from the Kem Kem Beds of Morocco since Christmas 2011 and it is still among my most prized fossils. I took a photo of the cross section today and noticed that it's a rather fat tooth. There are other old pictures of it in my Gallery but does anyone know what tooth position such a fat Carch tooth could be? Premax, maxilla, dentary? The tooth is 7 centimeters long. Thanks in advance.
  16. neural spine from kem kem?

    Ahoi! this piece of bone supposedly comes from Kem Kem. Someone said something about Pterosaurs, but they often do. The shape lets me think of a neural spine, the structure appears a bit fishy? What do you think? Aloha, J
  17. Spinosaur jaw

    Sold as jaw section. From Kem Kem. 140mm long. Lower jaw. Dpesnt say if teeth are from the jaw or added. Anyone know if ID is correct? Will be nice alongside my spino verts. Thanks
  18. Kem Kem Pterosaur vertebra?

    I have my doubts--aren't verts with the sort of ball-shaped end like this usually crocodile? It's been sold as a vertebra from Sirrocopterex. 3.5 cm in length. I'm suspecting croc, I'd love to be proved wrong though--a pterosaur vert would be a nice piece. Thanks for the help.
  19. Kem Kem Claw and Phalanx

    Seller doesn't know what it's from beyond claw and phalanx from Kem Kem in Morocco. Price is pretty good, so it tempts me if anyone has any idea what it's from. I have seen these crop up as raptor claws or deltadromeus claws elsewhere--which to me seems more speculative putting a name to it than it actually being from one of those species. But if anyone knows anything, that would be great.
  20. Kem Kem Vertebra

    Hello, this is been sold as unidentified Kem Kem bone. I'm guessing crocodile? But anyone knows more specific or differrnt that would be great. It is 5cm long. Thanks
  21. Flat elongated Kem Kem bone ID

    I've got this long flat bone from the Kem Kem with a wide base, it was presumably attached to a larger bone. It also seems like it's missing the tip. I thought it might be a small spinosaurid neural spine but it has a weird lump of bone on one side so it seems like it is something else. Is this lump a muscle scar? Or a healed wound? And could this bone be an odd spinosaurid neural spine or is it something entirely else?
  22. Moroccan theropod teeth

    Hello together, I think I may have asked about these before, posted together with other teeth. They were sold together with other fossils supposedly from kem kem, saying "teeth from Abelisaur/Dromaeosaur" which is not very helpful. Can any of you tell me more about them? Sorry if already got an answer for these, could not find one. Only the darkest one shows much of the serration, the sandy part may be repaired? @Troodon, @LordTrilobite, your expertise would be most welcome. @Abstraktum Thanks and greetings, J
  23. I'd love people's thoughts on this if anyone knows, but I find it odd that Kem Kem doesnt have much food fossils (other than Rebbachisaurus, which is kinda big to be prey) but has a number of carnivores. It's weird to me becausr most other formations have food fossils in abundance--Iguanodon at IoW, Ceratopsians and Hadrosaurs common in NA. I'm surprised Kem Kem doesnt really have its own common hadrosaur or iguanodon type. Anyone here know/have thoughts on why?
  24. Hello all I have a question about these three big crocodylomorph teeth from the Kem Kem beds in Morocco. The Kem Kem beds are Cenomanian (early late Cretaceous) in age. These are my three teeth: The left one is an 8,5 cm long tooth crown (maybe partial rooted but not too much) which is very slender. It has carinae ( Correct term for Crocodilians?) running all the way along the crown. The middle one is a rooted, slender tooth of 9 cm with a missing tip. The first time I saw this tooth for a moment I thought it would be a Pliosaur tooth, until I saw the location. I am not sure if the missing tip is chewing damage or just because the fossil broke. The complete tooth would have been 9,3-9,5 cm I think. It does have carinae, but they don’t seem to run along the entire 4 cm long crown. The root itself is around 5 cm long and hollow. The last one is a very robust 6 cm long tooth crown with clear carinae running along the entire tooth. This tooth is way smaller than the first one, but a lot more robust. My problem with these teeth is ID’ing them. Crocodile teeth usually aren’t easy but I really wanted to try to get some ID on these. Some background info: So far seven Crocodylomorphs are described in the Kem Kem beds. 1: First of, Araripesuchus rattoides I couldn’t really find any good pictures of teeth from this species, but I found this picture of a jaw of Araripesuchus wegneri from Niger My teeth certainly do not belong to this genus because of size and shape. 2: Next, Laganosuchus maghrebensis, a species who’s teeth also don’t look similar to mine. 3: Hamadasuchus rebouli has pretty distinctive teeth. They are usually serrated and a lot smaller. 4: Next up, Aegisuchus witmeri, a croc with a holotype without any teeth. However, the size estimates given to this crocodile are too small to contain such big teeth, so I also rule this one out. 5: We also have Kemkemia auditorei, but this species is only known from caudal vertebra. According to Wikipedia (I know, great source), this would have been a crocodylomorph with a size of 4 to 5 meters. I can’t really comment on teeth of this species, but when I compared it with the largest tooth recorded (9cm) of the biggest crocodile today (Saltwater crocodile), this tooth was even larger than the biggest of the Saltwater crocodile, while that specific individual must have been 1 to 2 meters bigger than the 4 to 5 meter estimate on Kemkemia, so I think we can rule that species also out. 6: The last one I feel pretty confident in ruling out is Lavocatchampsa sigogneaurusselae. Beside being way to small, it’s teeth looks nothing like mine. 7: Now onto the most famous Kem Kem crocodile: Elosuchus cherifiensis. The original description of the genus Elosuchus included these teeth. According to the description and this picture, I am pretty sure the tooth on the right does belong to this species. The other two teeth do not fit this description however. For the tooth on the left one I can believe it’s a different position in the jaw, but I am far from sure. The middle tooth is something else I think. It could of course be a case of heterodonty, but it differs quite a lot from the two others. So what do you guys think? Is this a case of heterodonty, or is there some huge, undescribed crocodylomorph present in the Kem Kem beds? Really looking forward to what you think. Pictures from: Larsson, H. C. E., en C. A.

  25. Kem Kem croc jaw fragments ID

    I've got five jaw fragments from the Kem Kem of which I think they are from crocodilians. Any ideas as to what genus or species these belong would be appriciated. 1. No idea what this jaw is from, but my best guess is some crocodilian. 2. I also don't know what this is but also probably some crocodilian. 3. This one has a hard layer of sediment covering it and it's missing the underside of the jaw. It looks a bit like the dented part of a Spinosaurus dentary but it's more likely also crocodilian. 4. Definitely crocodilian, has a typical croc texture (lots of dents). To me it looks like a right jugal with a part of the maxilla. 5. Also some crocodilian, resembles an Elosuchus jaw but it's pretty small so maybe a juvenile or some other croc. Have fun ID'ing!
