Galeocerdo shark teeth ID help

[josta4881]

Try to organize all my shark teeth and I have a couple Galeocerdo teeth that i need a little help with . All teeth were found in North Myrtle Beach, Cherry Grove South Carolina. Still new to id’s and reading everything I can but still learning. The last pictures, im pretty positive are Galeocerdo Cuvier but the others, I’m lost. Thank you!

Thank you! What are some of the characteristics that help you make that decision? Sorry to ask , I am just really tried to learn all that I can so I can id correctly and properly

Size, shape and thickness of the tooth, angle of the notch (less than 90 degrees), and strength of the serrations (with complex serrations, i.e., serrations on the serrations). The smaller ones with damage could possibly be one of the older species, but I doubt it.

Thank you ! The notch confuses me because I thought it had to be a 90 degree ish notch for it to be a Cuvier. I’m organizing all my teeth and really am trying my hardest to get them identified correctly and I’m trying to read and learn everything I can .
