Praearcturus
''Praearcturus'' is an extinct genus of scorpion known from the late Devonian of what is now Britain. It is the only genus in the family Praearcturidae and contains the single species ''Praearcturus gigas''. The type fossil was discovered in Rowlestone, England, and was described in 1871 by Henry Woodward (geologist), Henry Woodward. The species could reach a total length of nearly , making it one of the largest scorpions known. References Prehistoric scorpions {{Paleo-scorpion-stub ...

Scorpion
Scorpions are predatory arachnids of the order Scorpiones. They have eight legs, and are easily recognized by a pair of grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Their taxonomy is being revised to account for 21st-century genomic studies. Scorpions primarily prey on insects and other invertebrates, but some species hunt vertebrates. They use their pincers to restrain and kill prey, or to prevent their own predation. The venomous sting is used for offense and defense. During courtship, the male and female grasp each other's pincers and dance while he tries to move her onto his ...

Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began domina ...

Rowlestone
Rowlestone (also spelled Rowlstone) is a village and civil parish in the county of Herefordshire in England. It is a rural area with agriculture the main source of employment, and had only 87 residents in 2004, increasing to 180 at the 2011 Census. The area was historically Welsh-speaking. Two Welsh Bibles from Rowlestone, formerly stored in the Rowlestone vicarage and damaged by fire, are kept in the Herefordshire County archives. It is notable mainly for the Norman parish church of St. Peter, which contains some distinguished carvings, including a tympanum showing Christ in Majesty with four attendant angels. These carvings are of the same distinctive Herefordshire School as those at the nearby Church of St Mary and St David, Kilpeck The Church of St Mary and St David is a Church of England parish church at Kilpeck in the English county of Herefordshire, about 5 miles from the border with Monmouthshire, Wales. Pevsner describes Kilpeck as "one of the most perfect Norman c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century. The English language, the Anglican Church, and Eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Woodward (geologist)
Henry Bolingbroke Woodward (24 November 1832 – 6 September 1921) was an English geologist and paleontologist known for his research on fossil crustaceans and other arthropods. Woodward was born Norwich, England on 24 November 1832 and was educated at Norwich School. He became assistant in the geological department of the British Museum in 1858, and in 1880 keeper of that department. He became Fellow of the Royal Society in 1873, LL.D (St Andrews) in 1878, president of the Geological Society of London (1894–1896). He was awarded the Murchison Medal in 1884 and Wollaston Medal in 1906. Woodward was president of the Geologists' Association for the years 1873 and 1874, president of the Malacological Society in 1893–1895, president of the Museums Association for the year 1900, and president of the Palaeontographical Society from 1895 (upon the death of incumbent president T. H. Huxley) to his own death in 1921. He published a ''Monograph of the British Fossil Crustace ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
