| 説明 | Pterorhytis conradi (Dall, 1890) - fossil snail shell from the Pleistocene of North Carolina, USA. (abapertural view)The gastropods (snails & slugs) are a group of molluscs that occupy marine, freshwater, and terrestrial environments. Most gastropods have a calcareous external shell (the snails). Some lack a shell completely, or have reduced internal shells (the slugs & sea slugs & pteropods). Most members of the Gastropoda are marine. Most marine snails are herbivores (algae grazers) or predators/carnivores.Classification: Animalia, Mollusca, Gastropoda, Neogastropoda, Muricoidea, MuricidaeStratigraphy: lower Croatan Formation (a.k.a. lower James City Formation), Lower Pleistocene (= "unit D" of Ward & Blackwelder, 1987, Smithsonian Contributions to Paleobiology 61: 113-283.)Locality: Lee Creek Mine at Aurora, eastern North Carolina, USA |
