Hello, I'm new to this forum and I come here to ask for your help. I am graduating in Biology and my final paper is about identifying species of shark vertebrae from an archaeological site. The thing is nobody from my lab knows how to work with it and I spent the whole last year trying to work with these centra but I realized it is a really hard work, almost impossible. I come here to ask if any of you know some good papers about shark vertebrae that could help in my work, or anything else that could help me in this situation. I'd be so thankful!
