Kem Kem bone id

[JohnBrewer]

Hi guys

 

can anyone help with these 6 bones from Kem Kem?

 

@LordTrilobite @Troodon

 

 

They dont look theropod to me so I'm wondering turtle? Maybe A and D are phalanges? B, C and F humerus (humeruses/humerii, plural? hehe)

 

thanks

I agree with everything you said, the humeri (strangely enough, only one "i" in the plural form) seem to small to be theropod, especially with most of kem keys theropods being large.

[LordTrilobite]

I don't have a lot of experience with turtles.

 

Not sure about turtle. but Dinosaurs and crocs have fairly different bone structure. Croc is very dense. While dinosaur bone is more spongy. Also there are a few smaller Theropods present in Kem Kem. there is at least one type of dromaeosaurid.

 

I don't recognise these shapes at a glance though. Cool bones though.

[Miocene_Mason]

Yeah I don't have much experience with this either, it just looked like some turtle skeletons I'd seen. Out of curiosity, what type of smaller theropods inhabited the kem kem beds @LordTrilobite, the smallest I know of is the charcarodontid deltadromeus agilis.

[Troodon]

Pretty fragmented to make a definitive call.    Sections of processes from vertebrae?

D looks like a Centrum possible Croc.

FYI,  Deltadromeus is currently understood as a Neovenatoridae. 

There are Dromaeosaurid's in the Kem Kem like LordTrilobite said and although not described isolated teeth have been found.  Very little is understood from this region and new discoveries will certainly increase the number of dinosaurs described.

I think WhodamanHD may just have mispoken since Neovenatoridae are in the clade Carcharodontosauria.

 

But yeah. There are undescribed raptors/dromaeosaurids present. Small undescribed birds also seem to be present. There is still so much unknown in that region.

[Miocene_Mason]

Yeah I misspoke, thanks for the information though, might be useful at some point.

[JohnBrewer]

Thanks gents.

 

Olof, the bones are spongy so that knocks crocs out. I guess crocs had dense bone as ballast? I wonder if that's the same with turtle. 

 

Frank, I'm not 100% sure these examples are all broken bits. I should have photographed the ends too. Agree with a possible centrum.

I think turtle bones are more common in Kem Kem than people generally think. I also believe that they are often preserved hollow, so they can easily be mistaken for dinosaur bones. That said, no idea what these pieces are, but I have some similar ones.

Cannot hurt on the ones that have clean edges all but D looked broken
