Duria Antiquior
''Duria Antiquior, a more ancient Dorset'', was the first pictorial representation of a scene of prehistoric life based on evidence from fossil reconstructions, a genre now known as paleoart. The first version was a watercolour painted in 1830 by the English geologist Henry De la Beche based on fossils found in Lyme Regis, Dorset, mostly by the professional fossil collector Mary Anning. De la Beche had the professional artist Georg Scharf produce lithographic prints based on the painting, which he sold to friends to raise money for Anning's benefit. It was the first depiction of a scene from deep time to see even limited publication. The print was used for educational purposes and widely circulated in scientific circles; it influenced several other such depictions that began to appear in both scientific and popular literature. Several later versions were produced. Origin of the painting and the lithograph By 1830 Mary Anning was well known to the leading British geologists and ...

Lias (period)
The Early Jurassic Epoch (in chronostratigraphy corresponding to the Lower Jurassic Series) is the earliest of three epochs of the Jurassic Period. The Early Jurassic starts immediately after the Triassic-Jurassic extinction event, 201.3 Ma (million years ago), and ends at the start of the Middle Jurassic 174.1 Ma. Certain rocks of marine origin of this age in Europe are called "Lias" and that name was used for the period, as well, in 19th-century geology. In southern Germany rocks of this age are called Black Jurassic. Origin of the name Lias There are two possible origins for the name Lias: the first reason is it was taken by a geologist from an English quarryman's dialect pronunciation of the word "layers"; secondly, sloops from north Cornish ports such as Bude would sail across the Bristol Channel to the Vale of Glamorgan to load up with rock from coastal limestone quarries (lias limestone from South Wales was used throughout North Devon/North Cornwall as it conta ...

Penny Magazine
''The Penny Magazine'' was an illustrated British magazine aimed at the working class, published every Saturday from 31 March 1832 to 31 October 1845. Charles Knight created it for the Society for the Diffusion of Useful Knowledge in response to ''Chambers's Edinburgh Journal'', which started two months earlier. Sold for only a penny and illustrated with wood-engravings, it was an expensive enterprise that could only be supported by very large circulation. Though initially very successful—with a circulation of 200,000 in the first year—it proved too dry and too Whiggish to appeal to the working-class audience it needed to be financially viable. Its competitor—which included a weekly short story—grew more slowly, but lasted much longer. Early success During the first few years of publication ''The Penny Magazine'' was highly successful in building an audience selling over 200,000 copies in 1832 with an estimation of nearly one million readers that year and easily outsell ...

John Phillips (geologist)
John Phillips FRS (25 December 1800 – 24 April 1874) was an English geologist. In 1841 he published the first global geologic time scale based on the correlation of fossils in rock strata, thereby helping to standardize terminology including the term Mesozoic, which he invented. Life and work Phillips was born at Marden in Wiltshire. His father belonged to an old Welsh family, but settled in England as an officer of excise and married the sister of William Smith, a renowned English geologist. When both parents died when he was a child, Phillips's custody was assumed by Smith and Phillips was brought into Smith's London home during early 1815. During the next few years he attended various schools and helped his uncle with his geological research and writing; he also developed an interest in lithography (printing from prepared slabs of stone), and was among the earliest English practitioners of the process, experimenting with it between about 1816 and 1819.

Jura Mountains
The Jura Mountains ( , , , ; french: Massif du Jura; german: Juragebirge; it, Massiccio del Giura, rm, Montagnas da Jura) are a sub-alpine mountain range a short distance north of the Western Alps and mainly demarcate a long part of the French–Swiss border. While the Jura range proper (" folded Jura", ''Faltenjura'') is located in France and Switzerland, the range continues as the Table Jura ("not folded Jura", ''Tafeljura'') northeastwards through northern Switzerland and Germany. Name The mountain range gives its name to the French department of Jura, the Swiss Canton of Jura, the Jurassic period of the geologic timescale, and the Montes Jura of the Moon. It is first attested as ''mons Iura'' in book one of Julius Caesar's ''Commentarii de Bello Gallico''. Strabo uses a Greek masculine form ''ὁ Ἰόρας'' ("through the Jura mountains", ''διὰ τοῦ Ἰόρα ὄρους'') in his ''Geographica'' (4.6.11). Based on suggestions by Ferdinand de Saussure, early c ...

Georg August Goldfuss
Georg August Goldfuss (Goldfuß, 18 April 1782 – 2 October 1848) was a German palaeontologist, zoologist and botanist. Goldfuss was born at Thurnau near Bayreuth. He was educated at Erlangen, where he graduated PhD in 1804 and became professor of zoology in 1818. He was subsequently appointed professor of zoology and mineralogy at the University of Bonn. Aided by Count Georg zu Münster, he issued the important (1826–44), a work which was intended to illustrate the invertebrate fossils of Germany, but it was left incomplete after the sponges, corals, crinoids, echinoderms and part of the mollusca had been figured. A collection of Goldfuss' botanical specimens are housed at Bonn University. Goldfuss died in Bonn. In 1820, he coined the word ''protozoa'' to refer to single-celled organisms such as ciliate The ciliates are a group of alveolates characterized by the presence of hair-like organelles called cilia, which are identical in structure to flagellum, eukaryotic ...

Crinoid
Crinoids are marine animals that make up the class Crinoidea. Crinoids that are attached to the sea bottom by a stalk in their adult form are commonly called sea lilies, while the unstalked forms are called feather stars or comatulids, which are members of the largest crinoid order, Comatulida. Crinoids are echinoderms in the phylum Echinodermata, which also includes the starfish, brittle stars, sea urchins and sea cucumbers. They live in both shallow water and in depths as great as . Adult crinoids are characterised by having the mouth located on the upper surface. This is surrounded by feeding arms, and is linked to a U-shaped gut, with the anus being located on the oral disc near the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, in most crinoids the five arms are subdivided into ten or more. These have feathery pinnules and are spread wide to gather planktonic particles from the water. At some stage in their lives, most crinoids have ...

Argonaut (animal)
The argonauts (genus ''Argonauta'', the only extant genus in the family Argonautidae) are a group of pelagic octopuses. They are also called paper nautili, referring to the paper-thin eggcase that females secrete. This structure lacks the gas-filled chambers present in chambered nautilus shells and is not a true cephalopod shell, but rather an evolutionary innovation unique to the genus. It is used as a brood chamber, and to trap surface air to maintain buoyancy. It was once speculated that argonauts did not manufacture their eggcases but utilized shells abandoned by other organisms, in the manner of hermit crabs. Experiments by pioneering marine biologist Jeanne Villepreux-Power in the early 19th century disproved this hypothesis, as Villepreux-Power successfully reared argonaut young and observed their shells' development. Argonauts are found in tropical and subtropical waters worldwide. They live in the open ocean, i.e. they are pelagic. Like most octopuses, they have a rounde ...

Ammonite
Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids (i.e., octopuses, squid and cuttlefish) than they are to shelled nautiloids such as the living ''Nautilus'' species. The earliest ammonites appeared during the Devonian, with the last species vanishing during the Cretaceous–Paleogene extinction event. Ammonites are excellent index fossils, and linking the rock layer in which a particular species or genus is found to specific geologic time periods is often possible. Their fossil shells usually take the form of planispirals, although some helically spiraled and nonspiraled forms (known as heteromorphs) have been found. The name "ammonite", from which the scientific term is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams' horns. Pliny the Elder ( 79 AD near Pomp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belemnitida
Belemnitida (or the belemnite) is an extinct order of squid-like cephalopods that existed from the Late Triassic to Late Cretaceous. Unlike squid, belemnites had an internal skeleton that made up the cone. The parts are, from the arms-most to the tip: the tongue-shaped pro-ostracum, the conical phragmocone, and the pointy guard. The calcitic guard is the most common belemnite remain. Belemnites, in life, are thought to have had 10 hooked arms and a pair of fins on the guard. The chitinous hooks were usually no bigger than , though a belemnite could have had between 100 and 800 hooks in total, using them to stab and hold onto prey. Belemnites were an important food source for many Mesozoic marine creatures, both the adults and the planktonic juveniles, and likely played an important role in restructuring marine ecosystems after the Triassic–Jurassic extinction event. They may have laid between 100 and 1,000 eggs. Some species may have been adapted to speed and swam in the tur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regency Era
The Regency era of British history officially spanned the years 1811 to 1820, though the term is commonly applied to the longer period between and 1837. George III of the United Kingdom, King George III succumbed to mental illness in late 1810 and, by the Regency Act 1811, his eldest son George IV of the United Kingdom, George, Prince of Wales, was appointed prince regent to discharge royal functions. When George III died in 1820, the Prince Regent succeeded him as George IV. In terms of periodisation, the longer timespan is roughly the final third of the Georgian era (1714–1837), encompassing the last 25 years or so of George III's reign, including the official Regency, and the complete reigns of both George IV and his brother William IV of the United Kingdom, William IV. It ends with the accession of Queen Victoria in June 1837 and is followed by the Victorian era (1837–1901). Although the Regency era is remembered as a time of refinement and culture, that was the prese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pterosaur
Pterosaurs (; from Greek ''pteron'' and ''sauros'', meaning "wing lizard") is an extinct clade of flying reptiles in the order, Pterosauria. They existed during most of the Mesozoic: from the Late Triassic to the end of the Cretaceous (228 to 66 million years ago). Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger. There were two major types of pterosaurs. Basal pterosaurs (also called 'non-pterodactyloid pterosaurs' or 'rhamphorhynchoids') were smaller animals with fully toothed jaws and, typically, long tails. Their wide wing membranes probably included and connected the hind legs. On the ground, they would have had an awkward sprawling posture, but the anatomy of their joints and strong claws would have made them effective climbers, and some may have even lived in trees. Basal pterosaurs were insectiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
