Hello!
Here i have finally arranged all my gastropod taxa on plates. Just wanted to share it with you. Maybe you have some more ideas or spot mistakes in the classifications. Have a good week - from tomorrow i will spend some days in the Alps!

Hi Matthias,

Is it correct to assume these are all fossils?

Have a great time in the Alps.

oh yeah - i forgot sorry!
they are all from sediments of the Pearl River Delta, close to Hong Kong.
But pretty recent, not older than 10 000 years.
Thank you!
