Kem Kem croc jaw fragments ID

[BioBob]

I've got five jaw fragments from the Kem Kem of which I think they are from crocodilians. Any ideas as to what genus or species these belong would be appriciated.

1. No idea what this jaw is from, but my best guess is some crocodilian.

2. I also don't know what this is but also probably some crocodilian.

3. This one has a hard layer of sediment covering it and it's missing the underside of the jaw. It looks a bit like the dented part of a Spinosaurus dentary but it's more likely also crocodilian.

4. Definitely crocodilian, has a typical croc texture (lots of dents). To me it looks like a right jugal with a part of the maxilla.

5. Also some crocodilian, resembles an Elosuchus jaw but it's pretty small so maybe a juvenile or some other croc.

Have fun ID'ing!

And here are some better images of number 3.

I think most of the pieces kinda need more cleaning to properly see the anatomy.

And after that better photos are needed like you did for nr 3.

#3 does have the possibility of being Spinosaurid but like LordTrilobite said most need to be prepped to make a call.

You're right that I need to prep them more. Here are some better pictures of number 4 and 5 since those have been mostly preparated.

 

Number 5

 

Number 4

Nr. 5 looks like it could be part of an Elosuchus jaw. It's definitely croc for sure. I'm thinking Elosuchus lower jaw.

 

Nr. 4 Needs more prep. But it looks like the very back of the upper jaw. Might be able to match it with a species since the shapes are quite distinct.

Thanks!
