[car209]

Hey everybody ...I am so curious about these Teeth I found. I know 1 and 2 are hard to really tell. I have not cleaned them ..frankly Im not sure how. I dont want to ruin them. Are these Sharks Teeth even?

I'd probably go with Lemon for both 4 and 5
It's tuff with their condition though.
They could be the lower jaw teeth of a few different species.

Considering where you are they could be Hemipristis.
