A guide for the identification of Spinosaurine vertebrae from the Kem Kem group, Morocco.
MBL13 posted a topic in Fossil ID
Hello everyone,I've decided to open a chain of comments focusing on a popular theme: Moroccan spinosaurids. This is the first comment of a small series dedicated to analyse and document the diverse morphology of spinosaurids in the Kem Kem group. As an introduction,I'll be specifying how it will work,the rules and some guidance for those interested. First and foremost,the rules: 1)For correct identifications,I require images in various view(ventral and lateral at least) and with the highest quality possible. 2)Each comment will focuse on a specific morphotype,as such,only post images of specimens matching the description giving at the start. Any specimen from other morphotype won't be identified by me. 3)Other people are encouraged to post their specimens and help with the identification/s. Procedures: 1) A new comment will be posted each week, probably during the weekend,hour from Spain. 2) Around 4 specific comments are planed. 3) Each comment will discuss a specific morphotype (anterior cervicals,mid cervicals, posterior cervicals and cervicodorsal vertebrae). 4)At the start of each comment,I'll write a basic description of the respective morphology. 5) I'll describe in detail each vertebra contained in the four groups previously mentioned. 6) Images will be extracted/modified from the literature and complemented with additional specimens. 7) Concluding remarks: Taxonomic identification and limitations of the analysis. 8) References and acknowledgements will be posted after the main corpus of the comment is finished. For any questions, please comment below. My words might not be entirely clear.I encourage everyone to post their questions.- 14 replies

Hello, I'm new to this forum. In the last months I have been involved in a project regarding North Africa spinosaurids.Because of the reduced data I have, I want to know if anyone could share photos of their specimens.Most of the specimens I need are presacral vertebrae and posterior cranial bones(including,if possible,a braincase). Also, any information in favour of a second morphotype could be really helpful;even though I have already treated this point, I want different opinions on this topic. Thanks a lot in advance to anyone.

So sadly its paywalled as usual I hope to read it soon but the general theme of the abstract seems to suggest various taxonomic of spinosaurus family are no longer valid. Again until I read the paper I wont say anything more than personally I'm highly skeptical. https://www.sciencedirect.com/science/article/pii/S0195667120302068

I was told by a friend that most spinosaurus teeth are sigilmassasaurus. Is this true? If so, does this make spinosaurus rare and sigilmassasaurus the common one? Sorry about my limited knowledge on these things.

Fourth cervical vertebra of a Spinosaurid. Very likely Sigilmassasaurus due to the short dorsal spine and proportions of the postzygapophyses.
