Turritellinae
Turritellidae, common name the "tower shells" or "tower snails", is a taxonomic family of small to medium-sized sea snails, marine gastropod molluscs in the clade Sorbeoconcha. These snails are filter feeders. This method of feeding is somewhat unusual among gastropod mollusks, but is very common in bivalves. Shell description The shells of turritellid species have whorls that are more convex and an aperture which is more circular than it is in the auger shells which are similarly high-spired. The columella is curved and the thin operculum is horny. Anatomy of the soft parts These snails burrow into mud or sand. The foot is relatively small. Taxonomy The following five subfamilies were recognized in the taxonomy of Bouchet & Rocroi (2005): * Turritellinae Lovén, 1847 - synonyms: Zariinae Gray, 1850; Zeacolpini Marwick, 1971; Archimediellidae Starobogatov, 1982; Tachyrhynchinae Golikov, 1986 *Orectospirinae Habe, 1955 *Pareorinae Finlay & Marwick, 1937 *P ...

Columella (gastropod)
The columella (meaning "little column") or (in older texts) pillar is a central anatomical feature of a coiled snail shell, a gastropod shell. The columella is often only clearly visible as a structure when the shell is broken, sliced in half vertically, or viewed as an X-ray image. The columella runs from the apex of the shell to the midpoint of the undersurface of the shell, or the tip of the siphonal canal in those shells which have a siphonal canal. If a snail shell is visualized as a cone of shelly material which is wrapped around a central axis, then the columella more or less coincides spatially with the central axis of the shell. In the case of shells that have an umbilicus, the columella is a hollow structure. The columella of some groups of gastropod shells can have a number of plications or folds (the columellar fold, plaits or plicae), which are usually visible when looking to the inner lip into the aperture of the shell. These folds can be wide or narrow, prominent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Marwick
John Marwick (3 February 1891 – 17 August 1978) was a New Zealand Palaeontology, palaeontologist and geologist. Early life and family Marwick was born near Oamaru, New Zealand, on 3 February 1891, the son of Hugh Marwick, and his wife, Jane née Cuthbert. While at Waitaki Boys' High School he helped to collect fossil shells and learned the beginnings of how to classify mollusca, molluscs. He studied and taught at the University of Otago, and in 1912 gained an MA with first-class honours in with a thesis on geology. In 1915, he married Marion Ivy Mary Keys at Mosgiel. They had two sons and two daughters, all becoming science graduates. Career With the coming of the First World War Marwick joined the Royal New Zealand Army Medical Corps, New Zealand Medical Corps in 1916, and was posted to Egypt. He served there as a medical orderly in the New Zealand Division, and also in Palestine (region), Palestine, Sinai Peninsula, Sinai and Jordan. He won the Military Medal, and returned ...

He was left a paraplegic after contracting poliomyelitis at the age of four, but waas able to participate in field excursions. He graduated from the University of Otago with B.Sc. and M.Sc. He received the Hamilton Memorial Prize of the New Zealand Institute in 1926 and a D.Sc. in 1927. His main research interest was marine and non-marine malacofauna of New Zealand, both recent and fossil. He also specialised on fossil Foraminifera. After a long period of unemployment, Finlay was appointed to the Geological Survey of New Zealand in 1937, and in the same year he married Jean Dorothy Waterson Gillies.

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal ''Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While ... Sources {{biology-stub ...
