Brian G. Gardiner (biologist)
Brian George Gardiner PPLS (30 October 1932 – 21 January 2021) was a British palaeontologist and zoologist, specialising in the study of fossil fish (palaeoichthyology). Early life and education Gardiner was born on 30 October 1932 in Cashes Green, Gloucestershire. He was educated at Marling School, Stroud and then took a first degree in zoology at Imperial College London, where he specialised in entomology. This was followed by a PhD in palaeontology at University College London at which time he was a scientific associate at the Natural History Museum, London. Academic career Gardiner was appointed an assistant lecturer in palaeontology at Queen Elizabeth College in 1958, and was later made Professor of Palaeontology at the Department of Biology at the same college. Queen Elizabeth College later merged with King's College London (1985). In 1963, he worked on secondment at the University of Alberta, Edmonton. In 1969, Gardiner described seven new genera and species of p ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

CREDENTIAL
A credential is a piece of any document that details a qualification, competence, or authority issued to an individual by a third party with a relevant or ''de facto'' authority or assumed competence to do so. Examples of credentials include academic diplomas, academic degrees, Professional certification, certifications, security clearances, Identity document, identification documents, badges, passwords, user names, key (lock), keys, power of attorney, powers of attorney, and so on. Sometimes publications, such as scientific papers or books, may be viewed as similar to credentials by some people, especially if the publication was peer reviewed or made in a well-known Academic journal, journal or reputable publisher. Types and documentation of credentials A person holding a credential is usually given documentation or secret knowledge (''e.g.,'' a password or key) as proof of the credential. Sometimes this proof (or a copy of it) is held by a third, trusted party. While in some c ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Palaeontology
Paleontology, also spelled as palaeontology or palæontology, is the scientific study of the life of the past, mainly but not exclusively through the study of fossils. Paleontologists use fossils as a means to classify organisms, measure geologic time, and assess the interactions between prehistoric organisms and their natural environment. While paleontological observations are known from at least the 6th century BC, the foundation of paleontology as a science dates back to the work of Georges Cuvier in 1796. Cuvier demonstrated evidence for the concept of extinction and how life of the past was not necessarily the same as that of the present. The field developed rapidly over the course of the following decades, and the French word ''paléontologie'' was introduced for the study in 1822, which was derived from the Ancient Greek word for "ancient" and words describing relatedness and a field of study. Further advances in the field accompanied the work of Charles Darwin who p ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class (biology), class of Osteichthyes, bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fish fin, fins made of webbings of skin supported by radially extended thin bony spine (zoology), spines called ''lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister taxon, sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation (anatomy), articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they domi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Evolution Of Fish
Fish began evolving about 530 million years ago during the Cambrian explosion. It was during this time that the early chordates developed the skull and the vertebral column, leading to the first craniates and vertebrates. The first fish lineages belong to the Agnatha, or jawless fish. Early examples include ''Haikouichthys''. During the late Cambrian, eel-like jawless fish called the conodonts, and small mostly armoured fish known as ostracoderms, first appeared. Most jawless fish are now extinct; but the extant lampreys may approximate ancient pre-jawed fish. Lampreys belong to the Cyclostomata, which includes the extant hagfish, and this group may have split early on from other agnathans. The earliest Gnathostomata, jawed vertebrates probably developed during the late Ordovician period. They are first represented in the fossil record from the Silurian by two groups of fish: the armoured fish known as Placodermi, placoderms, which evolved from the ostracoderms; and the Acantho ...

Taxonomy
image:Hierarchical clustering diagram.png, 280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the Taxonomy (biology), classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchy, hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a Taxonomy for search e ...

Anatomy
Anatomy () is the branch of morphology concerned with the study of the internal structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine, and is often studied alongside physiology. Anatomy is a complex and dynamic field that is constantly evolving as discoveries are made. In recent years, there has been a significant increase in the use of ...

Linnean Society
The Linnean Society of London is a learned society dedicated to the study and dissemination of information concerning natural history, evolution, and taxonomy. It possesses several important biological specimen, manuscript and literature collections, and publishes academic journals and books on plant and animal biology. The society also awards a number of prestigious medals and prizes. A product of the 18th-century enlightenment, the society is the oldest extant biological society in the world and is historically important as the venue for the first public presentation of the theory of evolution by natural selection on 1 July 1858. The patron of the society is Anne, Princess Royal. Honorary members include: King Charles III of the United Kingdom, Emeritus Emperor Akihito of Japan, King Carl XVI Gustaf of Sweden (both of the latter have active interests in natural history), and the eminent naturalist and broadcaster Sir David Attenborough.

Witteberg
The Witteberg or Witteberge is a South African mountain range just off the south-west corner of Lesotho. The range, which rises to 2408 metres, stretches for about from Lundin's Neck in the east to Lady Grey in the west. The range lends its name to the Witteberg Series, the uppermost fossiliferous sequence of the Cape System of sedimentary rocks in South Africa. The Witteberg Series (340-375 Ma) consists of clastic, shoreline deposits of shales, sandstones, and quartzites, and lies below the plant-bearing and glacial beds of the Lower Karoo System. The Witteberg Series has yielded fossil fragments of ''Lepidodendron''-like plants and large numbers of the ichnogenus known as '' Spirophyton''. The upper part of the series is also rich in palaeoniscoid fauna. In 1969, Brian G. Gardiner PPLS, former professor of palaeontology at King's College, described 7 new genera and species of ray-finned fish from here – ''Australichthys longidorsalis'', ''Aestuarichthys fulcratus'', ...

Palaeoniscidae
Palaeoniscidae is an extinct family of "palaeoniscoid" ray-finned fishes (Actinopterygii). The family includes the genus ''Palaeoniscum'' and potentially other Palaeozoic and Mesozoic early actinopterygian genera. The name is derived from the Ancient Greek words παλαιός (''palaiós'', ancient) and ὀνίσκος (''oniskos'', 'cod-fish' or woodlouse). Historic background The family was first named "Palaeoniscini" by Charles Lucien Bonaparte in 1846, and "Palaeonisciden" by Carl Vogt in 1851. Later, the family name was standardized to Palaeoniscidae. The authorship of the family Palaeoniscidae is variably attributed to either Bonaparte or Vogt in the literature. Vogt ascribed the following genera to Palaeoniscidae: ''Palaeoniscum'', '' Platysomus'' (misspelled as ''Platysemius''), '' Amblypterus'', '' Eurynotus'', '' Pygopterus'', and ''Acrolepis''. With the exception of ''Palaeoniscum'', these genera were later placed in separate families ( Platysomidae, Amblypteridae) o ...

King's College London
King's College London (informally King's or KCL) is a public university, public research university in London, England. King's was established by royal charter in 1829 under the patronage of George IV of the United Kingdom, King George IV and the Arthur Wellesley, 1st Duke of Wellington, Duke of Wellington. In 1836, King's became one of the two founding colleges of the University of London. It is one of the Third-oldest university in England debate, oldest university-level institutions in England. In the late 20th century, King's grew through a series of mergers, including with Queen Elizabeth College and Chelsea College of Science and Technology (1985), the Institute of Psychiatry (1997), the United Medical and Dental Schools of Guy's and St Thomas' Hospitals and the Florence Nightingale School of Nursing and Midwifery (in 1998).
