Snails and Slugs: Phylum Mollusca, Class GastropodaSnails and Slugs: Phylum Mollusca, Class Gastropoda johncallahan Tue, 07/14/2009 - 13:51
The Class Gastropoda (in Phylum Mollusca) includes the groups pertaining to snails and slugs. The majority of gastropods have a single, usually spirally, coiled shell into which the body can be withdrawn. The shell of these creatures is often what is recovered in a fossil dig. Gastropods are by far the largest class of molluscs, comprising over 80% of all molluscs.
The presence of gastropods, at the Pollack site, provides evidence to validate the researchers beliefs that, years ago, the environment was of shallow-water, near-shore locality.
Below are a few notable taxa recovered from the Pollack Farm site.
- Turritella cumberlandia
- Diastoma insulaemaris
- Epitonium charlestonensis
- Urosalpinx cumberlandianus
- Tritonopsis ecclesiastica
- Nassarius sopora
- Oliva simonsoni
- Inodrillia whitfieldi
