Description

Crystal System: Hexagonal System Description: Phylum: Mollusca Class:Gastropoda Genus: Voluta Common Name: Snail Age: Mesozoic Location: Topanga Canyon, California Description: (3) specimens varying in size with fair detail in all three. The larger of the three has distinct banding form erosion. The remaining two are small with distinct conical shape. Physical Characteristics: The Gastropoda or gastropods, more commonly known as snails and slugs, are a large taxonomic class within the phylum Mollusca. The class Gastropoda includes snails and slugs of all kinds and all sizes from microscopic to quite large. There are huge numbers of sea snails and sea slugs, as well as freshwater snails and freshwater limpets, and land snails and land slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. There are 611 families of gastropods, of which 202 families are extinct, being found only in the fossil record.[3] Gastropoda (previously known as univalves and sometimes spelled Gasteropoda) are a major part of the phylum Mollusca and are the most highly diversified class in the phylum, with 60,000 to 80,000[3][4] living snail and slug species. The anatomy, behavior, feeding and reproductive adaptations of gastropods vary significantly from one clade or group to another. Therefore, it is difficult to state many generalities for all gastropods.
