Henry John Carter
Henry John Carter, FRS (18 August 1813 – 4 May 1895) was a surgeon working in Bombay, India, who carried out work in geology, paleontology, and zoology. He worked as an army surgeon in Bombay from 1859 on Her Majesty's Indian Service, Bombay Establishment. He edited a collection of geological papers on Western India, including a summary of the geology of India, which was published in 1857. Many items of his published work appeared in the journal of the Bombay Branch of the Royal Asiatic Society, and in the Annals of Natural History. He was elected a Fellow of the Royal Society in 1859. Life and work Carter joined the Devon and Exeter Hospital at the age of sixteen, and graduated from University College In a number of countries, a university college is a college institution that provides tertiary education but does not have full or independent university status. A university college is often part of a larger university. The precise usage varies f ... in 1837 and obt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcareous Sponges
The calcareous sponges or calcereans are sponges that make up the class Calcarea, characterized by spicules made of calcium carbonate in the form of high-magnesium calcite or aragonite. While the spicules in most species are triradiate (with three points in a single plane), some species may possess two- or four-pointed spicules.''Treatise on Invertebrate Paleontology'' Part E, Revised.

Unlike the far more common siliceous sponges, calcareans lack microscleres, tiny spicules which reinforce the flesh. In addition, their spicules develop from the outside-in, mineralizing within a hollow organic sheath. Biology All sponges in this class are strictly ma ...

Baerida
Baerida is an order of sea sponges in the subclass of Calcaronea Calcaronea is a subclass of sea sponges Sponges or sea sponges are primarily marine invertebrates of the animal phylum Porifera (; meaning 'pore bearer'), a basal clade and a sister taxon of the diploblasts. They are sessile filter feed ..., first described in 2000 by Radovan Borojevic, Nicole Boury-Esnault and Jean Vacelet. Baerida contains four families; two of these families ( Lepidoleuconidae and Petrobionidae) were formerly placed within the order Lithonida. Species of the order Baerida are leuconoid calcareous sponges with the skeleton either composed exclusively of micro-diactines, or in which microdiactines constitute exclusively or predominantly a specific sector of the skeleton, such as choano-skeleton or atrial skeleton. Large or giant spicules are frequently present in the cortical skeleton, from which they can partially or fully invade the choanoderm. In sponges with a reinforced cortex ...

Taxa Named By Henry John Carter
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
