Shark tooth

[Barasingha]

This tooth was found in a Miocene area a while ago.  I thought Mako at the time and didn't give it much more thought.  I have recently seen some makos someone else has found over the last couple years and they don't seem to have the bulk of this this.  This one is 2" long but a nice 1/2" thick.  Any help with ID is appreciated.

I would say it is a ;ower Carcharodon hastalis (white shark formerly known as mako) lower tooth from a large shark.

As they got real big the teeth became more robust.

 

See what the experts have to say before You label it though.

I'm certainly no expert, but I agree with ynot. The lower anterior teeth have particularly thick roots. 

Nice find!

I have one with a really thick, massive root almost as large as a Parotodus.  I have also seen very thick lower teeth in modern great whites as well.  There is a mechanical reason for this.  The lower teeth are used to grab and hold the prey while the upper teeth come down and do the cutting.  Thicker, well anchored teeth do a better job of holding.
