Tiger Shark Tooth? Topsail NC

[Luciano]

I found this tooth walking along south topsail beach. I was pretty surprised! It’s my 3rd year finding a nice tooth at this beach, and was excited to keep my streak going. I am pretty confident it was a tiger shark tooth judging by the angle and serrations on either side. I was just wondering if I might be wrong, or if there’s any cool details to know about this tooth in general: age estimates or such.

 

Dimensions: * the coin is the only relative scale item I have on hand. Sorry. 
estimate- 23.75mm x 28.5mm

Your guess would be correct, tiger shark.
