Here are some photos of a tooth found in the Atlantic ocean off Eastern NC. When I was cleaning the bunch of teeth I had this tooth stuck out immediately.
I have heard some arguments for both a very large mako and a worn meg....although no one can produce a meg that looks like this yet for comparison.
Measurements :
Side 1 = 4.10 inches
Side 2 = 3.86 inches
Width = 2.72 inches
What do you think?
