Ichthyosaurs
Ichthyosaurs (Ancient Greek for "fish lizard" – and ) are large extinct marine reptiles. Ichthyosaurs belong to the order known as Ichthyosauria or Ichthyopterygia ('fish flippers' – a designation introduced by Sir Richard Owen in 1842, although the term is now used more for the parent clade of the Ichthyosauria). Ichthyosaurs thrived during much of the Mesozoic era; based on fossil evidence, they first appeared around 250 million years ago ( Ma) and at least one species survived until about 90 million years ago, into the Late Cretaceous. During the Early Triassic epoch, ichthyosaurs and other ichthyosauromorphs evolved from a group of unidentified land reptiles that returned to the sea, in a development similar to how the mammalian land-dwelling ancestors of modern-day dolphins and whales returned to the sea millions of years later, which they gradually came to resemble in a case of convergent evolution. Ichthyosaurs were particularly abundant in the Late Tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ophthalmosaurus
''Ophthalmosaurus'' (meaning "eye lizard" in Greek) is an ichthyosaur of the Jurassic period (165–150 million years ago). Possible remains from the Cretaceous, around 145 million years ago, are also known. It was a relatively medium-sized ichthyosaur, measuring long and weighing . Named for its extremely large eyes, it had a jaw containing many small but robust teeth. Major fossil finds of this genus have been recorded in Europe with a second species possibly being found in North America. Description ''Ophthalmosaurus'' was a medium-sized ichthyosaur, measuring long and weighing . It had a robust, streamlined body that was nearly as wide as it was tall in frontal view. Like other derived ichthyosaurs ''Ophthalmosaurus'' had a powerful tail ending in a pronounced bi-lobed caudal fluke whose lower half was formed around the caudal spine whereas the upper lobe was made up entirely from soft tissue. The limbs of ''Ophthalmosaurus'' were short and rounded with the forelimbs bein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ichthyosaurus Somersetensis
''Ichthyosaurus'' (derived from Greek ' () meaning 'fish' and ' () meaning 'lizard') is a genus of ichthyosaurs from the Early Jurassic (Hettangian - Pliensbachian), with possible Late Triassic record, from Europe (Belgium, England, Germany, Switzerland, and Portugal). It is among the best known ichthyosaur genera, as it is the type genus of the order Ichthyosauria.Maisch MW, Matzke AT. 2000. The Ichthyosauria.

Plesiosauria
The Plesiosauria (; Greek: πλησίος, ''plesios'', meaning "near to" and ''sauros'', meaning "lizard") or plesiosaurs are an order or clade of extinct Mesozoic marine reptiles, belonging to the Sauropterygia. Plesiosaurs first appeared in the latest Triassic Period, possibly in the Rhaetian stage, about 203 million years ago. They became especially common during the Jurassic Period, thriving until their disappearance due to the Cretaceous–Paleogene extinction event at the end of the Cretaceous Period, about 66 million years ago. They had a worldwide oceanic distribution, and some species at least partly inhabited freshwater environments. Plesiosaurs were among the first fossil reptiles discovered. In the beginning of the nineteenth century, scientists realised how distinctive their build was and they were named as a separate order in 1835. The first plesiosaurian genus, the eponymous '' Plesiosaurus'', was named in 1821. Since then, more than a hundred valid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Triassic
The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between 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 Triassic ...

Society For Promoting Natural History
A society is a group of individuals involved in persistent social interaction, or a large social group sharing the same spatial or social territory, typically subject to the same political authority and dominant cultural expectations. Societies are characterized by patterns of relationships (social relations) between individuals who share a distinctive culture and institutions; a given society may be described as the sum total of such relationships among its constituent of members. In the social sciences, a larger society often exhibits stratification or dominance patterns in subgroups. Societies construct patterns of behavior by deeming certain actions or concepts as acceptable or unacceptable. These patterns of behavior within a given society are known as societal norms. Societies, and their norms, undergo gradual and perpetual changes. Insofar as it is collaborative, a society can enable its members to benefit in ways that would otherwise be difficult on an individua ...

Weston, Bath
Weston is a suburb and electoral ward of Bath in Bath and North East Somerset, South West England, located in the northwest of the city. Originally a separate village, Weston has become part of Bath as the city has grown, first through the development of Lower Weston in Victorian times and then by the incorporation of the village into the city, with the siting of much local authority housing there in the period after World War II. The ward includes Upper Weston, Weston village, Weston Park and the lower slopes of Primrose Hill. The area known as Lower Weston, south of Weston Road, is within Newbridge ward. History The earliest evidence of occupation comes from two Celtic caddy spoons found in the village in 1825. There are believed to have been used as ceremonial anointing regalia. During the 10th century, Weston had been divided into two estates. One, on the slopes of Lansdown was given by Edmund I to Aethelare in 946. Weston was the birthplace of Saint Alphege who was bo ...

Flood Myth
A flood myth or a deluge myth is a myth in which a great flood, usually sent by a deity or deities, destroys civilization, often in an act of divine retribution. Parallels are often drawn between the flood waters of these myths and the primaeval waters which appear in certain creation myths, as the flood waters are described as a measure for the cleansing of humanity, in preparation for rebirth. Most flood myths also contain a culture hero, who "represents the human craving for life". The flood-myth motif occurs in many cultures, including the Mesopotamian flood stories, Native American in North America, the Genesis flood narrative, '' manvantara-sandhya'' in Hinduism, and Deucalion and Pyrrha in Greek mythology. Mythologies One example of a flood myth is the '' Epic of Gilgamesh''. Many scholars believe that this account was copied from the Akkadian '' Atra-Hasis'', which dates to the 18th century BCE. In the Gilgamesh flood myth, the highest god, Enlil, decid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edward Lhuyd
Edward Lhuyd FRS (; occasionally written Llwyd in line with modern Welsh orthography, 1660 – 30 June 1709) was a Welsh naturalist, botanist, linguist, geographer and antiquary. He is also named in a Latinate form as Eduardus Luidius. Life Lhuyd was born in 1660, in Loppington, Shropshire, England, the illegitimate son of Edward Lloyd of Llanforda, Oswestry, and Bridget Pryse of Llansantffraid, Ceredigion, Llansantffraid, near Tal-y-bont, Ceredigion, Talybont, Cardiganshire in 1660. His family belonged to the gentry of south-west Wales. Though well-established, the family was not wealthy.
