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.

How spinosaurus teeth and bones are so common fossil on the market, the same time that we know very little about this dinosaur? Also, in my favorite fossil website, i have see 6-7 times, "spinosaurus vertebra" with cost from 200 to 500 dollars. They vertebra are really from spinosaurus?

I have in my collection a spinosaurus tooth from [name redacted by staff]. A nice and big tooth. But i have some questions about this. In the site, write that this tooth is from Spinosaurus Maroccanus. And i have read, that Spinosaurus Moroccanus is not real species and the fossils are from S. Aegyptiacus or Sigilmassasaurus . What you believe?

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..

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.

This paper looks to confirm the semi-aquatic lifestyle of Spinosaurids using oxygen isototopes in their bones. Direct evidence concerning spinosaurid diet was inconclusive since it appears that they also fed on dinosaurs and pterosaurs. Because of the shape of their jaw/teeth and fish remains in their stomach, the hypothesis of spinosaurs as “crocodile mimics” has been widely accepted. However, their postcranial anatomy differs relatively little from that of the usual large theropods, and is not particularly suggestive of aquatic habits. So the paper concluded that stable

Spanish Spinosaurids it's Implication to Kem Kem's Spinosaurids
Troodon posted a topic in General Fossil Discussion
I came across this paper in Fruitbat's library and it raised some questions so decided to see what others think. The paper studied Spinosaurid teeth that were found on the Iberian peninsula La Cantalera site and concluded that two morphotypes of spinosaurid teeth were recognized in the early Barremian of that site: both a Baryonychinae indet. and Spinosaurinae? indet. They ruled out attribution to other theropods or crocodylomorphs, although they remained cautious due to the scarce fossil record known. It also concluded that Spinosaurinae? indet. did not fit exactly with any- 7 replies
