Sigilmassasaurus vertebra

That's a really nice spinosaurus vertebra. I hope to one day own some spinosaurus vertebrae as well, it is one of my favourite dinosaurs.

Thanks, I quite like this specimen as well. But to be clear. This is not Spinosaurus, it is in Spinosauridae. But this morphology fits more closely with Sigilmassasaurus brevicollis, the other Spinosaurid that is present in the Kem Kem beds. Sigilmassasaurus seems to be more closely related to Baryonyx and Suchomimus than to Spinosaurus. So it's likely this animal also lacked a dorsal sail, though not a whole lot is known about this animal.

Oh, my bad. But it is still awesome and I still love all Spinosauridae. And also correct me if I am wrong but is Sigilmassaurus bones more rare on the market than Spinosaurus bones?

I don't think a conclusion can be reached on that at this time. Spinosaurid fossils are very common in the Kem Kem beds. But many cannot be identified to genus level. Spinosaurus itself is more popular so there might be a bias on the market. But I've seen many Sigilmassasaurus fossils on the market as well, which are almost invariably being sold as Spinosaurus because they are either misidentified or to be more salable. But I can say that all the Spinosaurid vertebrae I have that I can identify to genus are all Sigilmassasaurus. But this is likely due to Spinosaurus vertebrae being more expensive.
