I found my first megatooth today!
This was found in Calvert Cliffs Maryland, on my second kayaking trip down the Calvert formation. My and my friend visited beaches as we kayaked from Chesapeake Beach to Breezy Point and back. I found this tooth about half way down. Unfortunately this will be my last trip down Calvert Cliffs for a long time, so I am very happy I found this!
I believe this is Carcharocles Subauriculatus, could anyone verify this?
