Scylla posted a topic in Fossil NewsDino bone from the famous Lightning Ridge opal mines leads to first ID of this rare type of predatory dinosaur in Australia. A second, 20 million year older example also recognised during their studies. https://m.phys.org/news/2020-01-predatory-dinosaur-added-australia-prehistory.html
Troodon posted a topic in Fossil NewsA 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.
