Check out the teeth on that :)

I posted up a picture of a fossilized shark tooth the other day that came as a freebie with a coin I bought.  A month or so back I bought this one for my sons birthday but it came a bit late and is being held over till Christmas.  It's from a fully grown megalodon (extinct giant shark) that measured up to 20 meters long (or 4-5 times bigger than a great white shark).  The tooth is 10cm long and that's a 5c coin on it for scale.  It was found in dredge spoil that is used as road base in a coastal town in Georgia, USA.

I really like the serration around the edge. Super cool.

A bunch of these would make a fantastic set of steak knives!

But wait... there's MORE!

The modern sharks that have these triangular teeth also have the serrations along the edges as well.
Perfect design that hasn't changed in millennia

Here is the smaller cousin of Mark's tooth.!! Back in the 70's myself and a bunch of mates would spend our weekends on the local jetty fishing for sharks and big rays.!!
I wore this around my neck for the 'cool' factor until  one day managing to embed it quite deeply into my throat.!
My one and only shark attack survival story.! :dodgy:

it's amazing that after all this time they haven't changed much except the cutting section looks bigger/longer, or the root looks smaller on the younger tooth but both look like they come from the same sort of beast Sounds like you were lucky to walk away Robster
