Looks like quite the puzzle to put together, Sam!

Excellent tooth!

Well done.

Tim

Thanks Tim!

The matrix it was found in was crumbling to pieces along with the tooth so its lucky

none of the bits got lost!

Funfact: one of Saivodus's closest relatives is the 5 metre long Kaibabvenator whos teeth are (for an adult) 30 mm long however Saivodus adult teeth are 60 mm long twice the size of Kaibabvenator, so you found an ancient super shark tooth, the largest of this order (Ctenacanthiformes) is the "Texas super shark" who grew to about 8 metres long. Amazing find, I hope one day I get the chance to find a 60 mm adult tooth of Saivodus, well done very well done.
