Haravex Posted October 31, 2020 Share Posted October 31, 2020 The first one is somthing I cant assign to a family, the closest is this example of therizinosaurid 1 Link to comment Share on other sites More sharing options...
Troodon Posted October 31, 2020 Share Posted October 31, 2020 Nice bone. Possibly a humerus of some Crocodyliform Link to comment Share on other sites More sharing options...
LordTrilobite Posted October 31, 2020 Share Posted October 31, 2020 Definitely a left humerus of some type. If this is croc then it has some quite slender legs. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
Troodon Posted October 31, 2020 Share Posted October 31, 2020 Just guessing since we have little comparative material and the Kem Kem has several more gracile Crocodyliforms. Here is a Cretaceous Croc humerus from Brazil 2 Link to comment Share on other sites More sharing options...
LordTrilobite Posted October 31, 2020 Share Posted October 31, 2020 There's still a lot of mysteries in the Kem Kem beds. I have a mystery humerus as well. Haven't figured out what it's from yet either. The slenderness is similar to the one Haravex posted. But the deltopectoral crest seems to be a bit wider and higher. These seem to be different animals. But there's not a whole lot of good reference that I can find for crocs. And they seem to vary quite a bit too. Tip of my index finger to base of my thumb is about 14 cm. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
Troodon Posted October 31, 2020 Share Posted October 31, 2020 Its an unknown but both the specimen in question and Brazilian example have a pcd (posterior circular depression) which is or is not in your specimen . Here is one Crocodyliform its humerus length measures 8 cm no pictures. 2 Link to comment Share on other sites More sharing options...

Haravex Posted October 31, 2020 Author Share Posted October 31, 2020 Ok so this is my understanding 1 and 2 are both dorsal I suspect number 1 is a sub adult Spinosaurus. and 3 and 4 are associated and both caudal possibly mid? Link to comment Share on other sites More sharing options...

LordTrilobite Posted November 1, 2020 Share Posted November 1, 2020 11 hours ago, Haravex said: 1. 2. 1 looks like spinosaur dorsal. But is that the hint of a keel I see? I have a similar vertebra that's nearly identical except mine has a strong keel and the rugose plateau known from Sigilmassasaurus. 2 looks like dorsal of something else. Possibly croc maybe. 11 hours ago, Haravex said: 3. 4. These look like croc caudals to me. Pretty nice ones too. 1 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
Troodon Posted November 1, 2020 Share Posted November 1, 2020 1 looks like a very nice Spinosaurus centrum not sure I see a platform to call it Sigilmassasaurus 2 I dont see a Spinosaurid, not sure beyond that. Also nice 3 & 4 agree with LT look like Croc and super preserved one 2 Link to comment Share on other sites More sharing options...

I meant that the vert centrum I have looks like it's likely Sigilmassasaurus. And the one Haravex posted looks almost the same except that it seems to fit with Spinosaurus because it seems to lack those features. 1 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

Haravex Posted November 1, 2020 Author Share Posted November 1, 2020 Ok thanks for your help guys it means a lot, so my initial hunch of the two caudal vertebrae being croc was right must have been a bloody big crocodile (350g, pre to post zygapophysis 9.45cm, chevron facet to neural spine 10.2cm, parapophysis to parapophysis 7.45cm) Link to comment Share on other sites More sharing options...

Haravex Posted November 1, 2020 Author Share Posted November 1, 2020 Ok these are the final pieces I'm unsure of saying that I know where they are from number 5 is a cervical vertebrae and 6 is a dorsal looks to be juvenile by the unfused centrum.

I think your idea of it being some type of cervical vert might be the right direction. But other than that I really don't know. The closest I was able to find was Champsosaurus from the Hell Creek formation. But that would be quite something if Champsosaurs appeared in the Kem Kem group. The #6 is croc. I'm thinking anterior dorsal. Here's an old photo pre-prep that includes the verts I have that are similar to your #1 and #5.

LordTrilobite Posted November 1, 2020 Share Posted November 1, 2020 Indeed. Yeah those look similar but much smaller. 1 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

Also do you want to use these in that vertebrae topic you have? if so feel free to use them as examples. Link to comment Share on other sites More sharing options...

Alright cool. You're of course free to post them in the extended discussion there. Anything with a positive ID we can be confident in I can add to the first post as well for reference. 1 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
