Hi Looking thru an old collection of Isurus, three large and one smaller teeth showed a noticeable concave curve on the lingual side (I think I got that right). My first thought was pathological. In doing some "research" apparently there is something peculiar about the 3rd anterior tooth of Makos. Requesting your help with these. I tried to show by stacking the three curved ones with 2 regular shaped makos. Hope that shows clearly. What purpose would this "special" tooth serve? The brachiopod just could not resist getting in the picture. Thanks
