gastropd ID

Hi friends, could you please help me identifing this pliocenic gastropod? Planorbis?

[Peat Burns]

Can you tell us where these came from?  (General location, type of sediment)?

 

The first pic almost reminds me of the shell of the marine serpulid worm Spirorbis.  If that's not likely, based on what you know about the deposit, and it is a freshwater aquatic snail, it seems more comparable to Gyraulis.

Thanx Peat, It's comes from south Italy, I'dont know much about a sediment. This pictures are from a friend.

The first one is indeed a planorbid. Difficult to say more about the species because of the alteration of the shell.

 

The second one is terrestrial probably familly Hygromidae
