  1. 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.

  2. Abelisauridae - Raptor

    Hello, I see a lot of websites that sell abelisauridae teeth and raptor teeth, to me look the same size and shape, how can you tell the difference? (raptor tooth white backround), (abelisauridae tooth yellow backround)
  3. theropod teeth kem kem

    Hello ! I received 2 dinosaur teeth, from Kem Kem (cenomanian or albian). We can not accurately identify the species (if it is possible to identify them?). We think of a species of Abelisauridae, or maybe Dromaeosaurid (Deltadromeus agili?) (For the smallest)? Ideas? Teeth one (smallest): Second teeth :
  4. Abelisaurid tooth

    Acquired from a British fossil dealer in January 2019.
  5. Possibility of Getting Abelisauridae Fossils

    My favorite dinosaur is the Carnotaurus (hence the name) and I would love to have a fossil of one but I am aware that they are nearly impossible to come by. I was wondering if any of it’s relatives fossils are more common or easier to obtain. Thanks in advance!

    OK, I know it's gonna be an Abelisaurid, gotta check with you guys though! Pictures should say it all.
