Please help! Shark (?) Tooth found in North QLD, Australia

[Sottel]

Dear Community,

 

I need big help for small tooth that i found in North-east Queensland, Australia.

I suspect it to be a shark tooth, but a missing root makes the search much harder..

I'll be using metric sizes, or specifically mm= millimeter 

 

Here the hard facts I can give:

 

-ca 6mm long and 4,5mm wide

-triangular shape, no serrations

-no cusplets (maybe broken off?)

 

Ps: sorry if I am spamming pictures, wasn't sure what lighting would be best...

 

Thanks in advance for all the knowledge sharers and gatherers out there!
