Hi Ricardo

for me, It is ok for a lower tooth from Negaprion eurybathrodon. Do you collect another species from your site? And how do you collect in your site?

Sincerely

[ricardo]

Thank you daniel. I know there are other species there but I only collected this. I was collecting mollusca for study. It was by washing sediments.

All of best,

 

Ricardo

And how is the size of your sieve and the nature of th sediment?  because when your collect your mollusca you can lose the small species.
