  1. Wow three more Pterosaurs from the Kem Kem and all toothed one premaxilla is similar to the English ornithocheirid Ornithocheirus simus. Currently identified as Ornithocheirus cf simus. The other a premaxilla is referred to Coloborhynchus, bearing similarities to C. clavirostris from the Hastings Group of southern England, and C. fluviferox from the Kem Kem beds. Identified as Coloborhynchus sp. A. A mandibular symphysis closely resembles that of Anhanguera piscator from the Romualdo Member of the Santana Formation of Brazil. Identified as Anhanguera cf piscator In total, the Kem Kem pterosaur fauna includes at least nine species, of which three are ornithocheirids.

  2. A short paper and article on sauropod teeth from North Africa. Nothing new just more info.

  3. For those of you that thought you had identified your Kem Kem pterosaur beak here is another one to consider. This paper describes the new species Apatorhamphus gyrostega which brings the number of named Kem Kem azhdarchids to three, and the number of named Kem Kem pterosaurs to five. More to come or do some of these Azhdarchids actually reflect sexual dimorphism time will tell. Just keep that eraser handy...

  4. Kem Kem Beds fossil id 2

    This bone was purchased a while ago from a Moroccan dealer. Could come from the Kem Kem beds although I have not found the typical attachment of sediment to this bone, therefore my doubt about the origin. According to the dealer it is from a dinosaur. Can anyone confirm this?
  5. 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.

  6. 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
  7. Hi all, I acquired a partial Spinosauridae caudal spine recently from the Kem Kem Beds. However, I was told that this is a dinosauria indet. rib. The digger who provided me the fossil is experienced and trustworthy. Still, I would like to hear your thoughts on this fossil. Thank you. EDIT: Two others suggested that this is part of a scapula
  8. A very interesting paper authored some notable paleontologists. I was able to see a copy of the pre-proof paper. It describes 2 new cervical vertebrae and also reviews published material that provided an interesting insite into the Abelisauroids of the Kem Kem. Abelisauroids include both Abelisauridae and Noasauridae families. To summarize some of the conclusions: 1) One of the cervicals FSAC-KK-5016 established the presence of a small-bodied noasaurid taxon with similarities to Masiakasaurus of Madagascar. Further discoveries of this noasaurid are necessary to determine if it resembles Masiakasaurus in other aspects of its anatomy, such as a piscivory adapted dentition. One small tooth (GZG.V.19999), described by Richter et al. (2013) as abelisaurid-like was noted as similar to the teeth of Masiakasaurus. If Deltadromeus proves to be a noasaurid, which the paper suggest, then there are at least two noasaurid taxa present in the Kem Kem assemblage. 2) The second cervical an axis vertebra FSAC-KK-5015 is referred to as a small basal Abelisauridae that is neither a Carnotaurinae nor Majungasaurinae. 3) In reference to Richters et al paper (2013) the authors concluded that multivariate analysis may not be suitable for distinguishing dromaeosaurids or abelisaurids, but added that the small sample size (3 teeth for the morphotype: NMB-1671-R; GZG.V.19997; GZG.V.19998) decreased the accuracy of the results. It is possible that the teeth referred to Dromaeosauridae by Richter et al. (2013) are also noasaurid in origin. 4) A review of previously published material was also conducted and the following statement was made "The abelisaurid Rugops from the Eckhar Formation of Niger is here confirmed to also be present in the Kem Kem beds. " very cool...

  9. New Dinosaur Education Displays

    We did a lot more work on our shark stuff this summer than dinosaurs but we did change how display the non touch fossils. We added a few new items too but stayed light on additions. First up is our updated Cretaceous North Africa display. We added a really nice theropod tooth that fits @Troodon ‘s Morph Type 4 Dromaeosaurid-like profile hence the label for the program. We explain the ID difficulties of fossils so for a tooth like this they know we are not sure of what critter had this tooth. I am pretty happy with how this one looks. We give a nice picture of Cretaceous North Africa from two different times. This is an important part of our program and we have some nice fossils I think. We also have two touch fossils with this section. A limb bone that we go with Spino as the critter and one is a theropod very that we use to talk about Deltadromeus.
  10. Hello, could you please tell me what kind of mosasaur teeth are these? Thank you very much.
  11. Mosasaur jaw in matrix

    Hello, so I was thinking about buying this piece but i would love it if I could remove the matrix from it to make it look better. Is this possible? Thanks-
  12. Hello, so i was thinking about buying this tooth, what do you think of it? is it real? Thanks.
  13. Bone ID wanted. Thank you!

    Hello! I have this bone which i recieved in a lot, all bones and remains were advertised as from the Kem Kem Beds. It seems to be hollow, I think it may be crocodile? Thanks in advance for your input, could it be dinosaur? Reptile? Thanks!
  14. Robust foot claw from the Kem Kem

    Hi, Another question about a foot claw from the Kem Kem Beds. This is a weird looking claw that may or may not be theropod. It is quite robust and is 7cm in length, though i am having trouble telling which angles of the claw the photos come from. It does look like the underside has a couple of circular depression spots which could indicate theropod, though i am not confident and wanted to ask for opinions whether theropod is the likely candidate. Thanks.
  15. an interesting Kem Kem tooth

    I have been working on finding a Dromaeosaur indet tooth from Morocco for a few months. Most of the "raptor" teeth from the Kem Kem beds I have seen labeled as such ended up being more similar to the Abelisaur indet teeth and those I have found were over priced or gone before I could get then. This one is different and appears to fit the general profile of what I am looking for pretty well. I do not think it is a Carch and it does not look like an Abelisaur either. At the very minimum, and hopefully @Troodon agrees with me, it seems a good candidate for a multi-variant analysis. Any thoughts ?
  16. Nothing spectacular just a paper describing an ilium from an Abelsaurid from the Kem Kem beds of Morocco. I wanted to document this since we occasionally see this type of material for sale and all are described as Spinosaurus. Good to see this type of material published...now how about teeth https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0214055 An abelisaurid (Dinosauria: Theropoda) ilium from the Upper Cretaceous (Cenomanian) of the Kem Kem beds, Morocco Slimane Zitouni, Christian Laurent , Gareth dyke, Nour-Eddine Jalil Published: April 2, 2019
  17. Carcharodontosaurid tooth

    Acquired from a British fossil dealer in November 2018. Labeled Carcharodontosauridae indent. due to the presence of at least two carcharodontosaurids (Carcharodontosaurus saharicus and Sauroniops pachytholus) in the Kem Kem Beds.
  18. I've been looking for Moroccan pterosaur teeth, and have found this one from the Kem Kem beds for sale. I know there's fish teeth being sold as pterosaur teeth so I wanted to ask if anyone out there could confirm whether this is from a pterosaur? Thanks!
  19. Kem Kem Jawbone

    Recently I posted this fossil in the fossil preparations forum in order to get some assistance in cleaning the fossil. The bone comes from the Kem Kem Beds, so the sandy matrix was fairly easy to pick off with a pin vice and a DRY toothbrush I believe this is Carcharodontosaur because of the amount of space between tooth sockets and the presence of labial foramina (both of these features outlined in photographs) but I'm not 100% sure. The size of the fossil is 6x3x1 inches. I've been driving myself nuts trying to figure out what this thing is, so I've decided to post it here because I'm all out of ideas
  20. Recently I acquired this 7x3 inch bone from the Kem Kem Beds (seller specifically labeled it as coming from Tegana Formation, but I know this formation is no longer valid). When I received the bone I saw that it was covered in spots of sand, so I found my box of exacto knives and went to work. I spent all last night picking off any sand I could find and I think I got most of it. However, the bone is still quite dirty looking and my exacto knives cannot pick off any of the remaining sand-colored material. My first thought was to soak the whole thing in water but I once heard that soaking Moroccan fossils in water can ruin them. What should be my next move? Thanks for any suggestions!
  21. FOSSIL ID Kem Kem Beds

    I was given this by my father as a gift. All he knows, is is it is from the Kem Kem Beds. It looks like it may be a jaw bone on some kind as it has indentations for what looks like teeth? But I can't decide on if it's from a fish, turtle, crocodile, dinosaur or reptile or if it's just a fragmentary piece of bone. I would appreciate it if anyone can shed any light on this! Huge thanks in advance .
  22. This week's red flags This bone is being sold as a neural spine of a reptile or dinosaur. It's actually a pretty complete Chevron and could be dinosaurian. Needs lots of prepping to clean it up. Lots of Dromaeosaur raptor teeth being sold. All are either Abelisaurid indet or juvie Carcharodontosaurid Lots of caudal Vertebrae being sold as Spinosaurus or Carcharodontosaurus, most are Crocodyliforms, unknown or other Dino so post here before you buy Lots of rare phalanx toe bones from Dinosaurs or reptiles being sold this week. Most are Reptlian, Croc or turtle.
  23. A recent interpretation of the fossil remains Spinosaurus aegyptiacus proposed that it was specially adapted for a semi-aquatic mode of life—a first for any predatory dinosaur. To test some aspects of this suggestion this study developed a three-dimensional, digital model of the animal that incorporates regional density variations, lungs and air sacs, and the flotation potential of the model was investigated using specially written software. It was found that Spinosaurus would have been able to float with its head clear of the water surface, although it was laterally unstable and would tend to roll onto its side. The conclusion is that Spinosaurus was not highly specialized for a semi-aquatic mode of life. Furthermore, the floating characteristics of the Spinosaurus model were similar to those of models of other predatory dinosaurs, indicating that there was nothing special about the buoyant characteristics of this animal, and that other theropods could have successfully taken to water to the same degree as well. So Spinosaurus may have been specialized for a shoreline or shallow water mode of life, but would still have been a competent terrestrial animal. Interesting paper, very reputable and a big deal considering the source, The Royal Tyrrell Museum.

  24. This weeks round of red flags Recent listings offers a number of very long Spinosaur teeth at very low prices. Most of these have fake roots and more. Avoid and post here before you buy. A member just got taken last week so please be careful. Large rooted teeth are expensive. A finger bone is offered described from a Spinosaurus. I think its a carpal but we have no scientific evidence that this morphology is from a Spinosaur. Its a very nice indeterminate Theropod carpal. This bone is listed coming from a Carcharodontosaurus. We have no idea who is the owner of this bone, no associated foot material has been published for any large Kem Kem Theropod. Best identified as indeterminate Theropod. Lots of fake Dinosaur eggs continue to be listed. Please post interest before you buy. A pair of Aublysodon Premaxillary teeth offered for sale. Reminder this is no longer considered a valid species, they are best identified as Tyrannosaurid indet. Most likely Nanotyrannus.
  25. A very large Moroccan centrum is being offered for sale. Seller identifies it as a Carcharodontosaurus. In my opinion this looks more like a Sauropod with that very large pleurocoel in the lateral view. Not sure what is going on with that purplish looking material if its been added. Spinosaurus tail, caudal vertebra being offered for sale no mention of any repairs. The centrum does look like its from a Spinosaurid but the processes look composited. You can see the typical Moroccan matrix mix between those processss and centrum. Seller is advertising this as a Carcharodontosaurus toe bone. Identifying isolated toe bones to a species in the Kem Kem is very difficult not much is published that describes them. Its a nice bone buy it as an indeterminate Theropod. Lots of eggs are showing up for sale. Most are fake....this is just a reminder of that, please post interests here before you buy. I still see some dealers offering Rugops teeth for sale from the Kem Kem. Just a reminder that this species is only described from the Echkar Fm of Niger. Most of the teeth offered are Abelisaurid but are indeterminate from the Kem Kem until something is published. For fun saw this 4 figure listing, seller describes it as a petrified baby dinosaur skull with teeth, skin and brain matter coming out of the side of its mouth looks like an alien head to me.
