Pholadidea Acherontea
''Pholadidea'' is a taxonomic genus of marine bivalve molluscs in the subfamily Martesiinae of the family Pholadidae (the piddocks). Most members of ''Pholididea'' bore into shale, soft rock and coral for shelter, with the exception of ''Pholididea (Hatasia) wiffenae'', which is a wood-borer. Appearance The ''Pholididea'' are distinguished from the other genera in Martesiinae by having only on umbonal-ventral sulcus, a longitudinally-divided mesoplax, and either no metaplax and hypoplax, or a single plate caused by deposition of calcite in the periostratum. Occurrence ''Pholididea'' is known from the Eocene to the Holocene, while the subgenus ''P. (Hatasia)'' is known only from the Holocene. Species have been reported from the Palaeocene and Late Cretaceous, but these likely belong in other genera. Taxonomy The following taxonomic classifications exist in ''Pholididea'': Subgenera * '' Pholadidea (Pholadidea)'' Turton, 1819 * '' Pholadidea (Hatasia)'' Gray, 1851 Spe ...

William Turton
William Turton (21 May 1762 – 28 December 1835) was an English physician and naturalist. He is known for his pioneering work in conchology, and for translating Linnaeus' ''Systema Naturae'' into English. Biography He was born at Olveston, Gloucestershire and was educated at Oriel College, Oxford. He commenced in practice as a physician at Swansea, where he worked for fifteen years. He then moved in turn to Dublin, Teignmouth, and Torquay. He devoted his leisure time to natural history, especially conchology. He published several illustrated shell books, and a translation of Gmelin's edition of Linnaeus' ''Systema Naturae'' in 1806. His works on conchology have been described as "seminal". In 1817, while he was a physician at Teignmouth, he treated Tom Keats, youngest brother of the Romantic poet John Keats, for consumption. He moved to Bideford, Devon, in 1831, and died there. His shell collection is now located at the Smithsonian Institution. The bivalve genus '' Turtoni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
