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] |
Halka Chronic
Halka Chronic (February 26, 1923 – April 16, 2013) was a geologist who traveled and wrote books about the geology of different states. She studied the Grand Canyon, Walnut Canyon and then resided in Boulder, Colorado where she continued to study the Rocky Mountains. Early life Halka Chronic was born in Tucson, Arizona on February 26, 1923. She was born to Sidney F. and Marylka Modjeska Pattison as Helena Bainbridge Pattison. Halka spent her childhood summers in Corona Del Mar, California with her mother, an artist, and her brother, Karl. In her early life she took trips across the country to Cape Cod, Massachusetts. She developed her passion for traveling and sailing, as well as her skill as a watercolor painter, during these travels with her family. Halka attended the University of Arizona and Stanford University, and she received her Ph.D in Geology from Columbia University in 1949. Halka chose to focus on the fossils of Walnut Canyon, Arizona while earning her Ph.D. Halka ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Bivalve
Bivalvia (), in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. As a group, bivalves have no head and they lack some usual molluscan organs, like the radula and the odontophore. They include the clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. The gills have evolved into ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other hard surfaces. Some bivalves, such as the scallops and file shells, can swim. The shipworms bore into wood, clay, or stone and live inside these substances. The shell of a bivalve is composed of calc ...

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

Nucinellidae
Nucinellidae is a family of bivalves, in the order Solemyida. Its species are small and principally reside in deep-water environments. The species' average length is less than , the largest species being '' Nucinella boucheti'' (La Perna, 2005) at a length of . The family's characteristic features include large gills and reduced palps and their appendages; oval shells with few hinge teeth; they possess a single adductor muscle and one divided foot The foot ( : feet) is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is a separate organ at the terminal part of the leg made ... exhibiting papillae. The family contains two known genera: '' Huxleyia'' and '' Nucinella''. Speaking of ''Nucinella'', the genus' ligament system is of the simple arched type, lacking nymphae. Regarding the former, the system is "submerged" beneath its dorsal margin. Genera and species * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Herbert Girty
George Herbert Girty (1869–1939) was an American paleontologist. Biography Girty was educated at Yale University, where he obtained his PhD in 1894. During his postgraduate year at Stanford University in 1895, he was appointed as a paleontologist, and worked for the United States Geological Survey. He kept that position till he retired 44 years later. He is best known for his research on Permian faunas and for researches of Mississippian and Pennsylvanian invertebrates, in the Western United States The Western United States (also called the American West, the Far West, and the West) is the region comprising the westernmost states of the United States. As American settlement in the U.S. expanded westward, the meaning of the term ''the We ....
