Samsarasuchus
''Samsarasuchus'' is an extinct genus of archosauriform reptile from the Early Triassic of India. This genus has one known species, ''Samsarasuchus pamelae''. ''Samsarasuchus'' lived a few million years after the Permian-Triassic extinction, the largest known mass extinction event. It was a member of the Proterosuchidae, a group of successful crocodile-like reptiles that survived the extinction event and were among the earliest successful archosauromorphs. ''Samsarasuchus'' is known from several vertebrae recovered from the Panchet Formation of West Bengal, India. The formation has been dated to the Induan, the earliest stage of the Triassic period. It was classified in the Chasmatosuchinae, a subfamily of proterosuchids that contains a majority of genera in the family, including the Permian '' Archosaurus''. It is the only valid proterosuchid from India; ''Ankistrodon'', another proterosuchid previously described from the Panchet Formation, is considered a ''nomen dubium'' due t ...

Proterosuchidae
Proterosuchidae is an early family of basal archosauriforms whose fossils are known from the Late Permian and the Early Triassic. The highest diversity of genera is known from European Russia, but fossils are also known from South Africa, India, China, Australia, Brazil and possibly Argentina. The name comes from Greek πρότερο- ("first") and σοῦχος ("crocodile"). Description They were slender, medium-sized (about long, largest specimens reached ), long-snouted and superficially crocodile-like animals, although they lacked the armoured scutes of true crocodiles, and their skeletal features are much more primitive. The limbs are short and indicate a sprawling posture, like contemporary lizards but unlike most later archosaurs. Their most characteristic feature is a distinct down-turning of the premaxilla (the front of the upper jaw, which overhangs the lower jaw). Evolutionary history The terminal Permian catastrophe, which killed off 95% of all types of life, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pamela Lamplugh Robinson
Pamela Lamplugh Robinson (18 December 1919 – 24 October 1994) was a British paleontologist who worked extensively on the fauna of the Triassic and Early Jurassic of Gloucestershire and later worked in India on the Mesozoic and Gondwanan fauna. She helped establish the geology unit at the Indian Statistical Institute and directed research in vertebrate paleontology of India in the 1960s. Biography Robinson was born in Manchester to James Arthur Robinson and Ann (née Lamplugh) in 1919. She went to a private school and later the Manchester Girls' High School. After the divorce of her parents in 1938 she went to the University of Hamburg for premedical studies but this was interrupted by the war. Returning to England, she worked at the British Woollen Industries Research Association in Leeds where she attended evening lectures in Paleontology at Leeds University by Dorothy Rayner, which captured her interest. She worked from 1942 to 1945 at the Royal Ordnance factory at Thorp Arc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ankistrodon
''Ankistrodon'' is an extinct genus of archosauriform known from the Early Triassic Panchet Formation of India. First thought to be a theropod dinosaur, it was later determined to be a proterosuchid.

Panchet Formation
The Panchet Formation is an Early Triassic geological formation from the Damodar Valley of India. It is among the few geological formations outside of Russia, South Africa, and China that documents the recovery of global ecosystems immediately after the Permian-Triassic extinction. It shares similar traits to some of these other formations, including the dominance of ''Lystrosaurus'' and the primary predators being proterosuchid reptiles. It also preserves a diversity of temnospondyl amphibians.

Early Triassic
The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between 251.9 Ma and Ma (million years ago). Rocks from this epoch are collectively known as the Lower Triassic Series, which is a unit in chronostratigraphy. The Early Triassic is the oldest epoch of the Mesozoic Era. It is preceded by the Lopingian Epoch (late Permian, Paleozoic Era) and followed by the Middle Triassic Epoch. The Early Triassic is divided into the Induan and Olenekian ages. The Induan is subdivided into the Griesbachian and Dienerian subages and the Olenekian is subdivided into the Smithian and Spathian subages. The Lower Triassic series is coeval with the Scythian Stage, which is today not included in the official timescales but can be found in older literature. In Europe, most of the Lower Triassic is composed of Buntsandstein, a lithostratigraphic unit of continental red beds. The Early Triassic and partly also the Middle Trias ...

Fossil Taxa Described In 2023
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of ''Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before print. The ob ...

Prehistoric Reptile Genera
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indian Religions
Indian religions, sometimes also termed Dharmic religions or Indic religions, are the religions that originated in the Indian subcontinent. These religions, which include Buddhism, Hinduism, Jainism, and Sikhism,Adams, C. J."Classification of religions: Geographical"(), ''Encyclopædia Britannica'', 2007. Retrieved 15 July 2010. are also classified as Eastern religions. Although Indian religions are connected through the history of India, they constitute a wide range of religious communities, and are not confined to the Indian subcontinent. Evidence attesting to prehistoric religion in the Indian subcontinent derives from scattered Mesolithic rock paintings. The Harappan people of the Indus Valley civilisation, which lasted from 3300 to 1300 BCE (mature period 2600–1900 BCE), had an early urbanized culture which predates the Vedic religion. The documented history of Indian religions begins with the historical Vedic religion, the religious practices of the early Indo- ...

Saṃsāra
''Saṃsāra'' (Devanagari: संसार) is a Sanskrit word that means "wandering" as well as "world," wherein the term connotes "cyclic change" or, less formally, "running around in circles." ''Saṃsāra'' is referred to with terms or phrases such as transmigration/reincarnation, karmic cycle, or Punarjanman, and "cycle of aimless drifting, wandering or mundane existence". When related to the theory of karma, it is the cycle of death and rebirth. The "cyclicity of all life, matter, and existence" is a fundamental belief of most Indian religions. The concept of ''saṃsāra'' has roots in the post-Vedic literature; the theory is not discussed in the Vedas themselves. It appears in developed form, but without mechanistic details, in the early Upanishads. The full exposition of the ''saṃsāra'' doctrine is found in early Buddhism and Jainism, as well as in various schools of Hindu philosophy. The ''saṃsāra'' doctrine is tied to the karma theory of Hinduism, and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium,'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
