cheney416 Posted February 15, 2018 Share Posted February 15, 2018 I traded this piece in this forum few months ago, and i heard this is spinosaurus's neural spine. After i received this I searching and trying to match this bones with spinosaurus's neural spine and sail bone. They looks pretty similar with this piece but not perfect matched. So, I can't sure what is this bone piece is.. I hope i can identify this clearly. Do you have any idea of this pieces? +I feel really embarrassing about i wrote 'Kam Kam' on title... now i edit that. I feel i need to more study again It's almost 30cm long. And here is more details. Thanks for your help. 1 Link to comment Share on other sites More sharing options...

Rockwood Posted February 15, 2018 Share Posted February 15, 2018 The outside looks like bone, but could we get a better look at an end ? That looks more suspicious to me. Link to comment Share on other sites More sharing options...
Flx Posted February 15, 2018 Share Posted February 15, 2018 The cross section is not symetrical. This makes me think that it is probably not a neural spine but some other flat bone. E.g. part of a rib close to the proximal end or a part of the scapula. Link to comment Share on other sites More sharing options...

I going to search about dinosaur rib bone and scapula fossils. I think it's really hard to find out this bone is which dinosaur's bone...thanks for your help.

Troodon Posted February 15, 2018 Share Posted February 15, 2018 Looks to me to be the neural spine of a Spinosaurid 2 Link to comment Share on other sites More sharing options...

Troodon Posted February 15, 2018 Share Posted February 15, 2018 The width is correct as well as the curvatures on either side. Its a section very close to the centrum 1 Link to comment Share on other sites More sharing options...

Haravex Posted February 15, 2018 Share Posted February 15, 2018 At the lower end of the largest piece there is also sutures which are consistent with a neural spine. Link to comment Share on other sites More sharing options...
LordTrilobite Posted February 15, 2018 Share Posted February 15, 2018 Yup, Spinosaurid neural spine. And it looks like it has a nasty pathology too. Haven't we seen this specimen on the forum before btw? I'd even go as far as to say you could label this as Spinosaurus sp. as it looks too long for Baryonichynae, which would rule out Sigilmassasaurus. The widening at on end also is consistent with Spinosaurus aegyptiacus. And even if the breaks don't exactly fit. I think from the continuing patterns it's clear these three pieces belong together. And I think it would benefit from some repair to make it a nice display piece. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
Haravex Posted February 15, 2018 Share Posted February 15, 2018 Yes you have lt it was mine and traded so had already done research and got an id back up from here on the forum, also where there are breaks it has signs of water wear but does match up and was found from one location by a local Berber miner from a tunnel he had been digging I can also include the cave gps location if you would like however can't be certain of the layer. 2 Link to comment Share on other sites More sharing options...

I apologize for my little knowledge.. And yes, if you tell me the cave gps location, that will be really helpful for labeling. Thanks Haravex.
