Here’s another one I’m not sure about. I know we are still learning about the Kem Kem Beds daily, but I wanted to give this one a shot to see if any of the community had any input. I know you all know much more than I do. It was sold as Dino/Crocodyliform, so not much to go off of besides it was in the Cretaceous Kem Kem beds.

I’m wondering what everyone’s thoughts are on Spinosaurids in France? Is it possible that they were present in France? I’ve seen the subject show up a few times here before and was wondering what everyone’s thoughts were. Especially since Camarillasaurus has been confirmed a Spinosaurid, it helps support it as Camarillasaurus is the second species of Spinosaurid from Spain meaning they were clearly prevalent there, but it’s from Northeast Spain, not to far from France.

For those of us fortunate to obtain specimens before the ban was put in place here is a study published earlier this year that looked at a fair number of teeth. The blog provides a good read for collectors plus other readings in their references.. Blog http://rexmachinablog.com/2019/09/04/thailand-spinosaur-teeth/ Paper https://www.researchgate.net/publication/332698408_Spinosaurid_theropod_teeth_from_the_Red_Beds_of_the_Khok_Kruat_Formation_Early_Cretaceous_in_Northeastern_Thailand Wongko et al. found in their study that two distinct spinosaur morphotypes were present. Surprisingly, the team concluded that at least two spinosaurs are represented in Khok Kruat.

So after following nizaar ibrahim's study in 2014 I learned that spinosaurus walked on four legs and it spend a lot of time in water being a good swimmer. But recently I saw that some new studies have been published and then some others and I have lost track so if someone could please inform me about the latest discoveries and tell me if spinosaurus was a good swimmer and if he walked on four it would be much appreciated.
