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!
