There's a debate as to whether or not Great Whites evolved from Makos. There's also enough scientific evidence to suggest they do. See: This tooth can therefore be classified as either Isurus hastalis or Carcharodon hastalis. See: https://en.wikipedia.org/wiki/Isurus_hastalis

A few weeks back on a Tuesday I took a trip down to Westmoreland State Park (Virginia) to scout for kayaking and fossil hunting spots on the Potomac river. I put in at the park beach shortly after 8am and paddled south-eastish into the rising sun along the "bluffy" coast. Temperatures were in the low 30's but the air was still and the boat quickly warmed up. After about two hours of paddling I put ashore onto an unposted beach and tried sifting in some gravelly areas in about 12 inches of water. I sifted for about 30 minutes and came up with three nice large fossil shark teeth (Isurus hastalis), a snaggletooth shark tooth (Hemipristis serra), other smaller shark teeth, eagle ray pavement teeth, a dermal ray scute, and other bigger bone fragments (i could use help with identifying).. I continued the paddle after stowing the fossils, eventually turned, and paddled back to the beach by late afternoon. On the way back, the rising tide obscured most of the really neat potential fossil spots I'd seen on the way out. Lessons learned.. hunt only on unposted beaches or at the low tide water line, watch the tides, remember to bring booties, and this place has a lot of potential.

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?
