Hello! I'm a new member and I was hoping I could get some second opinions on some Kem Kem fossils I'm thinking about purchasing. I've only collected American species, and have been recently interested in bones out of the Kem Kem beds. I've stayed away thus far because of the stories of composite fossils and Frankenstein pieces, but I've come across a couple that I thought were interesting and fairly priced. Was hoping I could get some other thoughts before moving on any of them (wanna make sure they aren't composites or areas of fill look weird). I've attached pictures of three specimens I'm looking at. Any help would be greatly appreciated!

 

1) Spinosaurus Vertebra

2) Spinosaurus Rib  I think this one is what it is, prep work doesn't look the best, but just wanted confirmation I guess.

3) Carcharadontosaurus vertebra (transverse processes) I was wondering if I could get help on confirming the id on this one, not really sure what carcharadontosaur vertebrae are supposed to be like. Centrum is missing, not sure if that's important for the id.

The spinosaur vert looks okay. It might have had some work done on it. But it's hard to say. It's definitely mostly real. The centrum looks pretty good and at least part of the neural spine is real. But it may have been extended a bit with random bone. The same goes for the prezygapophyses on the front. So it's pretty okay, but could be better.

It's a distal spinosaur caudal vert.

The rib will need better photos of to judge properly. These aren't nearly adequate. It might be a composite, or it might not.

Nr 3 is interesting because it shows photos of two clearly different specimens. Both of them look real. One of them has repair. I've seen these pieces before but couldn't make much sense of the first one.

The first two photos are of a pretty weird specimen. It seems to be some type of neural arch. But the underside looks asymmetrical. And the neural spine looks almost nonexistent. There's sutures on what I presume is the front, which would make it part of the sacrum. It's really weird. And I don't think it's carcharodontosaur. And it seems to have quite a bit of pneumatization, so it might be pterosaur or dinosaur.

Then there's the other two photos that simply do not match the first two and have to be a different specimen. This one is more straight forward. It looks like a fairly typical theropod dorsal neural arch. Probably spinosaurid. One of the lateral processes looks like it's been broken off and glued back in place.
