Purbeckodon Batei
''Purbeckodon'' is an extinct genus of mammaliaforms, possibly belonging to Morganucodonta, that is known from Early Cretaceous deposits of southeastern Dorset, England. It was collected in the Purbeck Limestone Group of Dorset. It was first named by Percy M. Butler, Denise Sigogneau-Russell and P. C. Ensom in 2011 and the type species In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the spe ... is ''Purbeckodon batei''.

Early Cretaceous
The Early Cretaceous (geochronology, geochronological name) or the Lower Cretaceous (chronostratigraphy, chronostratigraphic name) is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 143.1 Megaannum#SI prefix multipliers, Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian–Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining Anoxic event#Cretaceous, early Aptian Oceanic Anoxic Event 1a (OAE1a) was dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java Plateau, Ontong Java-Manihiki Plateau, Manihiki-Hikurangi Plateau, Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history.

Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...

History Of Dorset
Dorset is a rural county in south west England. Its archaeology documents much of the history of southern England, from the earliest Mesolithic settlements and through the Roman, Saxon, and Medieval periods to the present. Pre-Roman The first known settlement of Dorset was by Mesolithic hunters, who returned to Britain at a time when it was still attached to Europe by a land-bridge, around 12,500 BC. The population was very small, maybe only a few thousand across the whole of Britain, and concentrated along the coast: in Dorset, such places as the Isle of Purbeck, Weymouth, Chesil Beach and Hengistbury Head, and along the Stour valley. These populations used stone tools and fire to clear some of the native oak forest for herding prey. Genetic experiments carried out on a Mesolithic skeleton from Cheddar Gorge (in the neighbouring county of Somerset) have shown that a significant part of the contemporary population of Dorset is descended from these original inhabitants of the ...

Fossil Taxa Described In 2011
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 ...

Cretaceous England
The Cretaceous ( ) is a geological period that lasted from about 143.1 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 77.1 million years, it is the ninth and longest geological period of the entire Phanerozoic. The name is derived from the Latin , 'chalk', which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation . The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was largely ice-free, although there is some evidence of brief periods of glaciation during the cooler first half, and forests extended to the poles. Many of the dominant taxonomic groups present in modern times can be ultimately traced back to origins in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Berriasian Life
In the geological timescale, the Berriasian is an age/stage of the Early/Lower Cretaceous. It is the oldest subdivision in the entire Cretaceous. It has been taken to span the time between 143.1 ±0.6 Ma and 137.05 ± 0.2 (million years ago). The Berriasian succeeds the Tithonian (part of the Jurassic) and precedes the Valanginian. Stratigraphic definition The Berriasian Stage was introduced in scientific literature by Henri Coquand in 1869. It is named after the village of Berrias in the Ardèche department of France. The largely non-marine English Purbeck Formation is in part of Berriasian age. The first rocks to be described of this age were the beds of the English Purbeck Formation, named as the Purbeckian by Alexandre Brongniart in 1829 following description by Henry De la Beche, William Buckland, Thomas Webster and William Henry Fitton. The base of the Berriasian, which is also the base of the Cretaceous System, has traditionally been placed at the first appearance of ...

Denise Sigogneau-Russell
Denise Sigogneau-Russell (born ''c.'' 1941/42) is a French palaeontologist who specialises in mammals from the Mesozoic, particularly from France and the UK. She is currently based at the Muséum National d'Histoire Naturelle. Background Denise Sigogneau-Russell completed her PhD in 1969 on therapsids - the forerunners of mammals - from South Africa, where she spent two years. In 1976 a Belgian amateur fossil hunter brought her a mammal tooth from a quarry in eastern France, and this inspired her to change direction and begin research on mammals from the Mesozoic.Kielan-Jaworowska, Z. 2013. ''In Pursuit of Early Mammals''. Indiana University Press. She subsequently studied them in France, Portugal, Madagascar, Morocco, and England. Zofia Kielan-Jaworowska said that due to Sigogneau-Russell's "scholarship and diligence, she has contributed enormously to the knowledge of early mammal evolution.". She was married to Donald E. Russell, also a palaeontologist specialising in mammals, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Purbeck Marble
Purbeck Marble is a fossiliferous limestone found in the Isle of Purbeck, a peninsula in south-east Dorset, England. It is a variety of Purbeck stone that has been quarried since at least Roman times as a decorative building stone. Geology Stratigraphically these limestone beds lie towards the top of the Durlston Formation of the Purbeck Group. They were deposited during the Berriasian age of the Early Cretaceous epoch. Purbeck Marble is not a metamorphic rock, like a true marble, but is so-called because it can take a fine polish. Its characteristic appearance comes from densely packed shells of the freshwater snail '' Viviparus''. Sussex Marble is similar in type. The 'marble' is properly classified as a biomicrudite, as it consists of large clasts (the snail shells) in a fine-grained limestone mud matrix. The individual marble beds (also known as 'seams'), lie between layers of softer marine clays and mudstone, laid down during repeated marine ingressions. Some of th ...
