Kurtzia Arteaga
''Kurtzia arteaga'' is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. Description The length of the shell attains 10.25 mm, its diameter 4 mm. (Original description) The small shell has an acute-fusiform shape. It contains about eight whorls. The initial whorl is extremely minute, the subsequent whorls slowly enlarge and minutely reticulate. The later whorls have a strongly marked shoulder, and are, when young, of a reddish-brown colour, which gradually changes with exposure to a light grey. The sculpture of the adult whorls consists of (on the body whorl about ten) prominent, slightly arcuate, nearly axial ribs, rather sharply nodose at the intersection with the angle of the shoulder, with wider interspaces and continuous to the siphonal canal. As to the spiral sculpture of major and minor threads, there are about ten of the former in front of the shoulder, of which two are visible behind the suture on the spire; the remainder – wh ...

Kurtzia Granulatissima
''Kurtzia granulatissima'' is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. Description The length of the shell attains 7 mm, its diameter 3 mm. The small, yellowish white shell is slender, andacute. It has a small smooth protoconch of a1½ whorl and 4½ subsequent sculptured whorls. The suture is distinct, not appressed, undulated by the ends of the ribs. The whorls show a prominent shoulder. The spiral sculpture consists of small sharp close-set threads covering the whole surface most prominent in the interspaces between the ribs and given a frosty appearance by the intersection of close fine sharp slightly elevated incremental lines. The other axial sculpture consists of (on the body whorl eight strong rounded ribs with wider interspaces extending to the siphonal canal from the preceding suture and not continuous up the spire. The aperture is narrow. The anal sulcus is wide and round but with no marked fasciole or subsutural cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kurtzia Aethra
''Kurtzia aethra'' is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. Description The length of the shell attains 8 mm, its diameter 3.3 mm. (Original description) The small, acute shell is pale brownish. Its smooth, acute protoconch consists of 2 whorls. The teleoconch consists of six subsequent whorls, the first of which has two peripheral spiral threads with an angle at the shoulder. There is other spiral sculpture of somewhat alternated small uniform close-set threads, made minutely scabrous by the intersection of sharp incremental lines and covering the whole surface. The; axial sculpture otherwise consists of six prominent sharp vertical ribs with much wider interspaces, practically continuous up the spire and extending from the suture to the siphonal canal. The aperture is narrow. The anal sulcus is shallow, rounded, not preceded by any obvious fasciole, close to the suture. The outer lip shows a thickened varix behind it, sharp ...

Kurtzia Ephaedra
''Kurtzia ephaedra'' is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. Description The length of the shell attains 8.3 mm, its diameter 3.2 mm. (Original description) The small, slender, acute shell is very pale brown or whitish. The apical whorl of the protoconch is minute, transparent, smooth, bubble-like, followed by 1½ faintly reticulate whorls. The 5½ subsequent whorls shows a deep appressed suture. The spiral sculpture consists of alternate threads with narrower interspaces, the major threads (on the spire two or three) rather prominent, especially the posterior one, which forms a sort of shoulder to the whorl, more conspicuous in the earlier whorls. The minor threads usually number one on the spire, but on the body whorl sometimes two or even three in the interspaces between the major threads. The threads are little or not at all swollen where they cross the ribs but are rendered harsh by the intersection of fine sharp close ...

"Classification and nomenclator of gastropod families". ''Malacologia'' 47(1-2). . 397 pp. Prior to 2011, both the subfamilies Mangeliinae and Oenopotinae had been placed in the family Conidae. In 2011, Bouchet, Kantor ''et al'' merged the two subfamilies into one taxon, which they elevated to the rank of family. This was based on anatomical characters and a dataset of molecular sequences of three gene fragments. Mangeliidae is a sister- clade to the family Raphitomidae As with their relatives in the family Conidae, species in the family Mangelidae use potent venoms to catch their prey. Through t ...

Paul Bartsch
Paul Bartsch (14 August 1871 Tuntschendorf, Silesia – 24 April 1960 McLean, Virginia) was an American malacologist and carcinologist. He was named the last of those belonging to the "Descriptive Age of Malacology". Early life Bartsch emigrated with his parents to the U.S.A in 1880, first to Missouri and then to Burlington, Iowa. As a child, he took up jobs in his spare time in several employments. He soon took an interest in nature, first by keeping a small menagerie at home, and during his high school years, collecting birds and preparing skins. He established a natural-history club in his home with a little museum and a workshop. By the time he went to the University of Iowa in 1893, he had collected 2,000 skins. Among his professors at the university were the University of Iowa were the geologist Samuel Calvin, botanists Thomas H. Macbride and Bohumil Shimek, and the zoologist Charles C. Nutting. He graduated from the university with a B.S. in 1896, and M.S. in 1899, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
