Hi. These three where found in St. Pete’s Florida on the beach. Is it possible the first one in top is a small great white? The serrations on both sides is causing me to think that. The middle tooth I think is hammerhead? based on the research I did. The bottom tooth I believe is sandbar based on how thin the root is and the length of the blade? Any feedback would be much appreciated. I’m still trying my best to ID these as accurately as possible. Thank you in advance!
