London, England
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as '' Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.

James Scott Bowerbank
James Scott Bowerbank (14 July 1797 – 8 March 1877) was a British naturalist and palaeontologist. Biography Bowerbank was born in Bishopsgate, London, and succeeded in conjunction with his brother to his father's distillery, in which he was actively engaged until 1847. In early years astronomy and natural history, especially botany, engaged much of his attention; he became an enthusiastic worker at the microscope, studying the structure of shells, corals, moss agates, and flints. He also formed an extensive collection of fossils. The organic remains of the London Clay attracted particular attention, and about the year 1836 he and six other workers founded The London Clay Club – the members comprising Dr Bowerbank, Frederick E. Edwards (1799–1875), author of ''The Eocene Mollusca'' ( Palaeontograph. Soc.), Searles Valentine Wood, John Morris, Alfred White (zoologist), N. T. Wetherell, surgeon of Highgate (1800–1875), and James De Carle Sowerby. In 1840, Bowerbank pu ...

Trinidad
Trinidad is the larger and more populous of the two major islands of Trinidad and Tobago. The island lies off the northeastern coast of Venezuela and sits on the continental shelf of South America. It is often referred to as the southernmost island in the West Indies. With an area of , it is also the List of Caribbean islands by area, fifth largest in the West Indies. Name The original name for the island in the Arawak language, Arawaks' language was which meant "Land of the Hummingbird". Christopher Columbus renamed it ('The Island of the Holy Trinity, Trinity'), fulfilling a vow he had made before setting out on his third voyage. This has since been shortened to ''Trinidad''. History Island Caribs, Caribs and Arawaks lived in Trinidad long before Christopher Columbus encountered the islands on his third voyage on 31 July 1498. The island remained Spanish until 1797, but it was largely settled by French colonists from the French Caribbean, especially Martinique.Besson, ...

Colonial Office
The Colonial Office was a government department of the Kingdom of Great Britain and later of the United Kingdom, first created to deal with the colonial affairs of British North America but required also to oversee the increasing number of colonies of the British Empire. Despite its name, the Colonial Office was never responsible for all Britain's Imperial territories; for example, protectorates fell under the purview of the Foreign Office, and British India was ruled by the East India Company until 1858 (the British Raj ruled the India Office as a result of the Indian Mutiny), while the role of the Colonial Office in the affairs of the Dominions changed as time passed. It was headed by the Secretary of State for the Colonies, also known more informally as the Colonial Secretary. First Colonial Office (1768–1782) Prior to 1768, responsibility for the affairs of the British colonies was part of the duties of the Secretary of State for the Southern Department and a committe ...

Stratum
In geology and related fields, a stratum ( : strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either '' bedding surfaces'' or ''bedding planes''.Salvador, A. ed., 1994. ''International stratigraphic guide: a guide to stratigraphic classification, terminology, and procedure. 2nd ed.'' Boulder, Colorado, The Geological Society of America, Inc., 215 pp. . Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as either being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both ''bed'' and ''lamina''.Neuendorf, K.K.E., Mehl, Jr., J.P., and Jackson, J.A. , eds., 2005.

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. 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 ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Cambridge Greensand
The Cambridge Greensand is a geological unit in England whose strata are earliest Cenomanian in age. It lies above the erosive contact between the Gault Formation and the Chalk Group in the vicinity of Cambridgeshire, and technically forms the lowest member bed of the West Melbury Marly Chalk Formation.Cambridge Greensand
