Nephrops
''Nephrops'' is a genus of lobsters comprising a single extant species, '' Nephrops norvegicus'' (the Norway lobster or Dublin Bay prawn), and several fossil species. It was erected by William Elford Leach in 1814, to accommodate ''N. norvegicus'' alone, which had previously been placed in genera such as ''Cancer'', '' Astacus'' or ''Homarus''. ''Nephrops'' means "kidney eye" and refers to the shape of the animal's compound eye. Although the species in the genus ''Metanephrops'' were previously included in ''Nephrops'', molecular phylogenetics suggests that the two genera are not sister taxa, ''Nephrops'' being more closely related to ''Homarus'' than either is to ''Metanephrops''. Most of the fossil species assigned to the genus ''Nephrops'' are known only from partial remains, and their affinities are not certain. They include: *''Nephrops reedi'' Carter, 1898 – Pliocene, England *''Nephrops costatus'' Rathbun, 1918 – Pleistocene, Panama *''Nephrops maoensis'' Rathbun, 19 ...

Nephrops Norvegicus
''Nephrops norvegicus'', known variously as the Norway lobster, Dublin Bay prawn, ' (compare langostino) or ''scampi'', is a slim, coral-colored lobster that grows up to long, and is "the most important commercial crustacean in Europe". It is now the only extant species in the genus '' Nephrops'', after several other species were moved to the closely related genus ''Metanephrops''. It lives in the north-eastern Atlantic Ocean, and parts of the Mediterranean Sea, but is absent from the Baltic Sea and Black Sea. Adults emerge from their burrows at night to feed on worms and fish. Description ''Nephrops norvegicus'' has the typical body shape of a lobster, albeit narrower than the larger-bodied genus ''Homarus''. It is pale orange in colour, and grows to a typical length of , or exceptionally long, including the tail and claws. A carapace covers the animal's cephalothorax, while the abdomen is long and segmented, ending in a broad tail fan. The first three pairs of legs bear cl ...

Lobster
Lobsters are Malacostraca, malacostracans Decapoda, decapod crustaceans of the family (biology), family Nephropidae or its Synonym (taxonomy), synonym Homaridae. They have long bodies with muscular tails and live in crevices or burrows on the sea floor. Three of their five pairs of legs have claws, including the first pair, which are usually much larger than the others. Highly prized as seafood, lobsters are economically important and are often one of the most profitable commodities in the coastal areas they populate. Commercially important species include two species of ''Homarus'' from the northern Atlantic Ocean and Scampi (other), scampi (which look more like a shrimp, or a "mini lobster")—the Northern Hemisphere genus ''Nephrops'' and the Southern Hemisphere genus ''Metanephrops''. Distinction Although several other groups of crustaceans have the word "lobster" in their names, the unqualified term "lobster" generally refers to the clawed lobsters of the fam ...

Metanephrops
''Metanephrops'' is a genus of lobsters, commonly known as scampi. Important species for fishery include '' Metanephrops australiensis'' (Australian scampi) and '' Metanephrops challengeri'' (New Zealand scampi). It differs from other lobsters such as '' Homarus'' and '' Nephrops norvegicus'' in that its two main claws are of equal size, rather than being differentiated into a ''crusher'' and a ''pincher''. There are 18 extant species recognised in the genus: Species *'' Metanephrops andamanicus'' (Wood-Mason, 1891) *'' Metanephrops arafurensis'' (De Man, 1905) *'' Metanephrops armatus'' Chan & Yu, 1991 *'' Metanephrops australiensis'' (Bruce, 1966) *'' Metanephrops binghami'' (Boone, 1927) *''Metanephrops boschmai'' (Holthuis, 1964) *'' Metanephrops challengeri'' (Balss, 1914) *'' Metanephrops formosanus'' Chan & Yu, 1987 *''Metanephrops japonicus'' (Tapparone-Canefri, 1873) *'' Metanephrops mozambicus'' Macpherson, 1990 *'' Metanephrops neptunus'' (Bruce, 1965) *''Metanephro ...

Homarus
''Homarus'' is a genus of lobsters, which include the common and commercially significant species ''Homarus americanus'' (the American lobster) and '' Homarus gammarus'' (the European lobster). The Cape lobster, which was formerly in this genus as ''H. capensis'', was moved in 1995 to the new genus ''Homarinus''. Description ''Homarus'' is one of three extant genera of clawed lobsters to show dimorphism between claws – a specialisation into a crushing claw and a cutting claw. The other similar genera are '' Nephrops'', which is much more slender, and has grooves along the claws and the abdomen, and '' Homarinus'', the Cape lobster from South Africa, which is even smaller, and has hairy claws. tp://ftp.fao.org/docrep/fao/009/t0411e/t0411e09.pdf Subfamily Nephropinae Dana, 1852 pp. 51–86 in Holthuis (1991). While analyses of morphology suggest a close relationship between ''Homarinus'' and ''Homarus'', molecular analyses using mitochondrial DNA reveal that they are not ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 143.1 to 66 mya (unit), million years ago (Mya). It is the third and final period of the Mesozoic Era (geology), 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 Sea level#Local and eustatic, eustatic sea levels that created numerous shallow Inland sea (geology), inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land.

Decapod Genera
The Decapoda or decapods, from Ancient Greek δεκάς (''dekás''), meaning "ten", and πούς (''poús''), meaning "foot", is a large order (biology), order of crustaceans within the class Malacostraca, and includes crabs, lobsters, crayfish, Caridea, shrimp, and Dendrobranchiata, prawns. Most decapods are scavengers. The order is estimated to contain nearly 15,000 extant species in around 2,700 genera, with around 3,300 fossil species. Nearly half of these species are crabs, with the shrimp (about 3,000 species) and Anomura including hermit crabs, king crabs, porcelain crabs, squat lobsters (about 2500 species) making up the bulk of the remainder. The earliest fossils of the group date to the Devonian. Anatomy Decapods can have as many as 38 appendages, arranged in one pair per body segment. As the name Decapoda (from the Greek language, Greek , ', "ten", and , '':wikt:-pod, -pod'', "foot") implies, ten of these appendages are considered legs. They are the pereiopods, foun ...

Oligocene
The Oligocene ( ) is a geologic epoch (geology), epoch of the Paleogene Geologic time scale, Period that extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from Ancient Greek (''olígos'') 'few' and (''kainós'') 'new', and refers to the sparsity of Neontology, extant forms of Mollusca, molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major chang ...
