Gryphaea Dilatata
''Gryphea dilatata'', common name "devil's toenail" is a species of Jurassic oyster, an extinct marine (ocean), marine bivalve Mollusca, mollusc in the family Gryphaeidae. This fossil oyster is frequently found in abundance in the localities where it occurs. It belongs to the Oxfordian stage, Oxfordian and Kimmeridgian clays of the Jurassic and can grow to a diameter in excess of . It lived a sedentary life-style, settled on the sea bed and was a filter feeder. Its abundance at certain localities — such as Furzy Cliff, Weymouth, Dorset, Weymouth, Dorset, (England) — suggests it often formed large beds of hundreds of individuals. It is closely related to the similar species ''Gryphaea dilobotes''.

James Sowerby
James Sowerby (21 March 1757 – 25 October 1822) was an English naturalist, illustrator and mineralogist. Contributions to published works, such as ''A Specimen of the Botany of New Holland'' or ''English Botany'', include his detailed and appealing plates. The use of vivid colour and accessible texts were intended to reach a widening audience in works of natural history. Biography James Sowerby was born in Lambeth, London, his parents were named John and Arabella. Having decided to become a painter of flowers his first venture was with William Curtis, whose ''Flora Londinensis'' he illustrated. Sowerby studied art at the Royal Academy and took an apprenticeship with Richard Wright. He married Anne Brettingham De Carle and they were to have three sons: James De Carle Sowerby (1787–1871), George Brettingham Sowerby I (1788–1854) and Charles Edward Sowerby (1795–1842), the Sowerby family of naturalists. His sons and theirs were to contribute and continue the enormous vo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Furzy Cliff
Furzy Cliff, also known as Jordan's Cliff, is located on the coast near the village of Preston, just to the east of Weymouth, Dorset, England. It is at the northeastern end of Weymouth Beach, looking out over Weymouth Bay to Portland Harbour and the Isle of Portland. Close by to the east is Bowleaze Cove. Just inland to the north are Jordan Hill and the remains of the Jordan Hill Roman Temple. On the top of the cliff there is a large grass area with good views. Furzy Cliff consists of Oxford Clay with a thin Corallian Limestone layer over this. Mudslides frequently occur on the narrow undercliff and the base is mainly made up of clay material. Fossilized examples of '' Gryphaea dilatata'', commonly called "devil's toenail", an extinct species of Jurassic oyster, and '' Metriacanthosaurus parkeri'', a theropod dinosaur, can be found in the Oxford Clay. In 1816–17, the artist John Constable painted '' Weymouth Bay: Bowleaze Cove and Jordon Hill'', including Furzy Cliff, wh ...

Prehistoric Bivalves
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 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 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gryphaea Dilatata Lateral
''Gryphaea'', one of the genera known as devil's toenails, is a genus of extinct oysters, marine bivalve mollusks in the family Gryphaeidae. These fossils range from the Triassic period to the middle Paleogene period, but are mostly restricted to the Triassic and Jurassic. They are particularly common in many parts of Britain. These oysters lived on the sea bed in shallow waters, possibly in large colonies. The complete fossils consist of two articulated valves: a larger gnarly-shaped shell (the "toenail") and a smaller, flattened shell, the "lid". The soft parts of the animal occupied the cavity between the two shells, just like modern oysters. The shells also feature prominent growth bands. The larger, curved shell sat within the mud on the sea floor. These shells are sometimes found in fossil plates along with ''Turritella'', clams, and sometimes sharks' teeth and fossilized fish scales. Its distribution is common in areas of both Europe.

Jurassic Coast
The Jurassic Coast is a World Heritage Site on the English Channel coast of southern England. It stretches from Exmouth in East Devon to Studland Bay in Dorset, a distance of about , and was inscribed on the World Heritage List in mid-December 2001. The site spans 185 million years of geological history, coastal erosion having exposed an almost continuous sequence of rock formation covering the Triassic, Jurassic and Cretaceous periods. At different times, this area has been desert, shallow tropical sea and marsh, and the fossilised remains of the various creatures that lived here have been preserved in the rocks. Natural features seen on this stretch of coast include arches, pinnacles and stack rocks. In some places the sea has broken through resistant rocks to produce coves with restricted entrances and, in one place, the Isle of Portland is connected to the land by a barrier beach. In some parts of the coast, landslides are common. These have exposed a wide range of fossils, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gryphaea Arcuata
''Gryphaea arcuata'' is an extinct species of foam oyster, a bivalve mollusc in the family Gryphaeidae from the Early Jurassic of Europe. It is commonly referred to in English folklore as the 'devils toenail' due to its supposed resemblance to the devil's 'cloven hoof'.

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.

Dorset
Dorset ( ; archaically: Dorsetshire , ) is a county in South West England on the English Channel coast. The ceremonial county comprises the unitary authority areas of Bournemouth, Christchurch and Poole and Dorset (unitary authority), Dorset. Covering an area of , Dorset borders Devon to the west, Somerset to the north-west, Wiltshire to the north-east, and Hampshire to the east. The county town is Dorchester, Dorset, Dorchester, in the south. After the Local Government Act 1972, reorganisation of local government in 1974, the county border was extended eastward to incorporate the Hampshire towns of Bournemouth and Christchurch. Around half of the population lives in the South East Dorset conurbation, while the rest of the county is largely rural with a low population density. The county has a long history of human settlement stretching back to the Neolithic era. The Roman conquest of Britain, Romans conquered Dorset's indigenous Durotriges, Celtic tribe, and during the Ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weymouth, Dorset
Weymouth is a seaside town in Dorset, on the English Channel coast of England. Situated on a sheltered bay at the mouth of the River Wey, south of the county town of Dorchester, Weymouth had a population of 53,427 in 2021. It is the third largest settlement in Dorset after Bournemouth and Poole. The history of the town stretches back to the 12th century and includes roles in the spread of the Black Death, the settlement of the Americas and the development of Georgian architecture. It was a major departure point for the Normandy Landings during World War II. Prior to local government reorganisation in April 2019, Weymouth formed a borough with the neighbouring Isle of Portland. Since then the area has been governed by Dorset Council. Weymouth, Portland and the Purbeck district are in the South Dorset parliamentary constituency. A seaside resort, Weymouth and its economy depend on tourism. Visitors are attracted by its harbour and position, halfway along the Jurassic Coast ...

Kimmeridgian
In the geologic timescale, the Kimmeridgian is an age in the Late Jurassic Epoch and a stage in the Upper Jurassic Series. It spans the time between 157.3 ± 1.0 Ma and 152.1 ± 0.9 Ma (million years ago). The Kimmeridgian follows the Oxfordian and precedes the Tithonian. Stratigraphic definition The Kimmeridgian Stage takes its name from the village of Kimmeridge on the Dorset coast, England. The name was introduced into the literature by French geologist Alcide d'Orbigny in 1842. The Kimmeridge Clay Formation takes its name from the same type location (although this formation extends from the Kimmeridgian stage of the Upper Jurassic into the Lower Cretaceous). It is the source for about 95% of the petroleum in the North Sea. Historically, the term Kimmeridgian has been used in two different ways. The base of the interval is the same but the top was defined by British stratigraphers as the base of the Portlandian (''sensu anglico'') whereas in France the top was defined as t ...

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...
