m.e.clark Posted April 7, 2018 Share Posted April 7, 2018 Hello, For academics purpose, I must identify parts of a fine specimen of Bothriolepis canadensis. I've spent a great deal of time trying to find how these parts were called, and couldn't find a convincing answer. One of my guess is that the anterior central structure shown on the pictures is the preorbital recess, but I'm pretty unsure of what would be the two cavities on its side, if it is indeed the preorbital recess. My second interrogation concerns the posterior end, where there are two mores plates, in V shapes. Then again, I have no clue what those might be. Therefore here I am, seeking help from more knowledgeable people on the subject. Thank you! Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted April 7, 2018 Share Posted April 7, 2018 Hello, and a very warm welcome to TFF from Morocco! I can't help with your query, but that's a gorgeous specimen. Did you find this yourself? Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
m.e.clark Posted April 7, 2018 Author Share Posted April 7, 2018 Thank you! And oh, no, I wish I did, though. It's part of my university's collection. Link to comment Share on other sites More sharing options...

m.e.clark Posted April 7, 2018 Author Share Posted April 7, 2018 At Miguasha National Park, in the province of Quebec, Canada! The area is protected and designated as a UNESCO World Heritage Site for its fossils. Link to comment Share on other sites More sharing options...
Miocene_Mason Posted April 8, 2018 Share Posted April 8, 2018 I’m not anywhere near sure but perhaps posterior and anterior superognathals nostrils and the postnasal foramen. source: Here awesome fossil to look at! “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

jdp Posted April 8, 2018 Share Posted April 8, 2018 I think you're seeing the internal surface of the premedian and lateral plates here. Link to comment Share on other sites More sharing options...
m.e.clark Posted April 9, 2018 Author Share Posted April 9, 2018 @Fossildude19 Oh trust me I spent hours on google, but they always give the dorsal plates when it comes to the head, never the ventral ones... Thank you for the welcome! @jdp @WhodamanHD Thank you for the suggestions! Anyone has an idea for the posterior weird fin-like plates at the bottom of the picture?

Fossildude19 Posted April 9, 2018 Share Posted April 9, 2018 @m.e.clark Perhaps the odd posterior plates are the "Dermal Pelvic Girdle" ?
