Another tooth added to the collection, a 4.2 inch rooted Carcharodontosaurus tooth and a smaller one. It has some really nice colours to it! Just wanted to say as well I'm really enjoying this forum and already I've met some awesome people

I know that T. rex used to be considered the biggest meat eating theropod dinosaur until the discovery of Giganotosaurus, but Spinosaurus is now considered the biggest theropod of all time. Who first considered Spinosaurus to be larger than T. rex. Is it possible that the emergence of giant carcharodontosaurs and tyrannosaurs in North America and Asia prompted ankylosaurids to develop tail clubs to fend off those predators.

Interesting find on online today, do you think it is real?

Hello! Good morning to all my friends from my favorite forum ! Unfortunately my English is not very good, but I would like some help, please, for this fossilized tooth. I know there is no publication of any fossilized skull, and unfortunately it is rare to find publications on the fossils of Moroccan teeth ... But I believe this tooth does not fit with a Carcharodontosaurus. By the morphological characteristics, it fits more with a Dromaeosauridae family. What do you think? Hugs to all!

The theropod landscape of the Kem Kem deposits continue to be more muddled with new discoveries and research but that should not surprise anyone. I've made several post about multiple Spinosaurid and Carcharodontosaurid in the Kem Kem and it continues to be supported by recent publications. The attached paper describes a femur that supports the concept that Abelisaurid's were in the Kem Kem. We are seeing teeth...so that's good. The paper however looks at the region: Figure 2 below, included in that paper, identifies the main theropod fauna of the region. The abbreviation KKCA under Morocco stands for Kem Kem Compound Assemblage. Please note that under KKCA there are two Spinosaurids mentioned Sigilmassasaurus and Spinosaurus indet. The paper concludes that there is to much ambiguity in the material studied to assign it to Spinosaurus aegyptiacus and further reevaluation is needed. Boy that sure puts an arrow through Ibrahim's Spino redesign. It also states that Kemkemia auditorei, paper attached, may be a crocodyliform or like the paper suggest a spinosaurid. The figure also shows two Carcharodontosaurid: Carcharodontosaurus and Sauroniops. Also Rugops is shown exclusive to Niger. More changes will come and hopfully in some lifetime we will have answers. So if you want to follow proper convention all Spino and Carch material should be identified has indeterminate but if you have that need to have a species name that's okay no one will know.
