Help Please with shells and (things)

[britsnana]

Thanks for the information, the only one that may? be partialy fossilized is the Olividae, the rest are not I think it is the way the light hits it from the scope. The little black things do not have  any features other than a few pits,some are round some are flat some are long but all are as shiny  and smooth as black sharks teeth are. Like I said I am just starting with the shells and your Identifacation page helps so very much. I just wasn't sure about the first one because it is a lot fatter and the lip is out farther than the other one.
Thanks again
