Verbeekinidae
Verbeekinidae are a family of large fusulinaceans characterized by subspherical, planispirally coiled tests and a long coiling axis. The wall is composed of a dense outer tectum and inner alveolar keriotheca. They are most prominent in Japan and Southeast Asia.https://www.mindat.org/taxon-P113009.html Lower taxa As presently defined by ( Loeblich & Tappan, 1988) the Verbeekinidae includes three subfamilies: Verbinkininae, Missellinindae, and Pseudodoliolininae. The family is entirely Permian, with a range from the Wolfcampian (L Perm.) to the Ochoan (U Perm.) Discussion In 1964 Loeblich and Tappan included the Verbeekininae (=Verbeekinidae, sensu 1988) and Neoschwagerininae (= Neoschwagerinidae sensu 1988) in the Verbeekinidae.

Fusulinacea
The Fusulinacea is a superfamily in the Fusulinida in which the test is spherical, discoida, or fusiform; commonly coiled, less often uncoiling in the late stage, numerous chambers per whorl; test wall of microgranular calcite (as for the order) in one to four layers. Tunnels or secondary foramina may result from partial resorption and secondary deposition may produce chomata, parachomate, tectoria, and axial fillings. Range: M Devonian (Givetian) - U Permian The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleoz ... (Djulfian ) Families The Fusulinacea, as revised in Loeblich and Tappan, 1988, includes 7 families, 27 subfamilies, and 164 genera. The families are: * Loeblichidae * Ozawainellidae * Fusulinidae * Schwagerinidae * Staffelllidae * Verbeekinidae * Neoschwageriidae—lis ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Helen Niña Tappan Loeblich
Helen Niña Tappan Loeblich (October 12, 1917 – August 18, 2004) was an American micropaleontologist who was a professor of geology at the University of California, Los Angeles, a United States Geological Survey (USGS) biostratigrapher, and a scientific illustrator whose micropaleontology specialty was research on Cretaceous foraminifera. Early life Dr Helen Nina Tappan Leoblich was born on October 12, 1917, in Norman, Oklahoma. She came from a well-educated background. Her mother Mary Pearl Jenks Tappan was a math teacher at Cornell, and her father, Frank Girard Tappan, was a Dean of Electrical Engineering at the University of Oklahoma. Education Tappan Loeblich earned her BS in 1937 and her Master's in 1939, both in geology from the University of Oklahoma. Her master's thesis was on mid-Cretaceous foraminifera of Oklahoma and Texas. At the University of Oklahoma, she met her future husband and long time scientific collaborator, Alfred R. Loeblich Jr, in chemistr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permian
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ochoan
The Ochoan is a stage in the Permian stratigraphy (and an age in the geologic timescale) of North America. The Ochoan age is roughly simultaneous with the Changhsingian age in the timescale of the ICS. This post-Guadalupian stage is known for high levels of evaporite An evaporite () is a water-soluble sedimentary mineral deposit that results from concentration and crystallization by evaporation from an aqueous solution.

Treatise On Invertebrate Paleontology
The ''Treatise on Invertebrate Paleontology'' (or ''TIP'') published by the Geological Society of America and the University of Kansas Press, is a definitive multi-authored work of some 50 volumes, written by more than 300 paleontologists, and covering every phylum, class, order, family, and genus of fossil and extant (still living) invertebrate animals. The prehistoric invertebrates are described as to their taxonomy, morphology, paleoecology, stratigraphic and paleogeographic range. However, taxa with no fossil record whatsoever have just a very brief listing. Publication of the decades-long ''Treatise on Invertebrate Paleontology'' is a work-in-progress; and therefore it is not yet complete: For example, there is no volume yet published regarding the post-Paleozoic era caenogastropods (a molluscan group including the whelk and Common periwinkle, periwinkle). Furthermore, every so often, previously published volumes of the ''Treatise'' are revised. Evolution of the proje ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schwagerinidae
The Schwagerinidae comprise a family of large, generally fusiform, foraminiferans included in the Fusulinacea, a superfamily of fusulinids, locally abundant during the later Carboniferous ( Pennsylvanian) and most of the Permian. M.L. Thompson (1964) gives the following diagnosis: Shell large, fusiform to irregularly cylindrical, planispiral, involute in most, irregularly uncoiled in some; spirotheca thick, composed of tectum and alveolar kariotheca; septa fluted in end zones of primitive genera, fluted completely across shell and to tops of chambers of more advanced genera; tummel singular in most forms, multiple in one genus; axial fillings absent to massive; chomata massive to slight. As with all fusulinaceans, the Schagerinidae are a shallow water form which in places make up a significant portion of the sediment, now limestone. More familiar genera include '' Schwagerina'', ''Triticites'', and ''Parafusulina ''Parafusulina'' is a genus of foraminifera included in the fusu ...
