Check this out and tell me what you think it is

Ya, I think you guys are right. I 'Googled' it and found lots of different pictures of "megaladon" teeth. Wow, it's cool to have. According to what I read, it's WAY bigger than a great white shark.

As far as we know the Megalodon shark species went extinct 1.6 million years ago, and were approx 16-20 meter long. (50 feet) or so average.
They were 3 times bigger than a great white.
