''Eutrichiurides'' ("true '' Trichiurus'' resemblance") is an extinct genus of cutlassfish known from the early Paleocene to the early Oligocene. Taxonomy Species within this genus include: * †''E. africanus'' Dartevelle & Casier, 1949 - mid-late Paleocene (Selandian to Thanetian) of Angola ( Landana Formation) * †''E. delheidi'' (Leriche, 1908) (type species) - Early Oligocene of Belgium ( Boom Clay) (=''Trichiurides delheidi'' Leriche, 1908) * †''E. orpiensis'' (Leriche, 1906) - Early Paleocene of Morocco & North Dakota, USA ( Cannonball Formation), Late Paleocene of Belgium, Early Eocene of England * †''E. plicidens'' ( Arambourg, 1952) - middle Eocene (early Lutetian to middle Bartonian) of Alabama, USA ( Tallahatta, Lisbon and Gosport Sand Formations), potentially Bartonian of Libya * †''E. goberti'' Casier, 1944 - Early Eocene of Tunisia ( Gafsa-Metlaoui Basin) * †''E. termieri'' (Arambourg, 1952) - Late Paleocene/Early Eocene of Morocco (Ouled Abdoun Basin) ' ...

Cutlassfish
The cutlassfishes are about 45 species of predatory ray-finned fish in the family Trichiuridae of the order Scombriformes found in seas throughout the world. Fish of this family are long, slender, and generally steely blue or silver in colour, giving rise to their name. They have reduced or absent pelvic fin, pelvic and caudal fins, giving them an eel-like appearance, and large fang-like teeth. Some of the species are known as scabbardfishes or hairtails; others are called frostfishes because they appear in late autumn and early winter, around the time of the first frosts. The earliest known remains of cutlassfish are isolated teeth assigned to ''Eutrichiurides'' from the Danian, Early Paleocene of Morocco, the United States, and Angola, although their affinities are subject to question. The earliest known body fossil of a cutlassfish is a specimen tentatively assigned to ''Anenchelum'' from the Ypresian, Early Eocene of Italy. Classification This list of species follows FishB ...

Early Paleocene
The Danian is the oldest age (geology), age or lowest stage (stratigraphy), stage of the Paleocene Epoch or series (stratigraphy), Series, of the Paleogene Period or system (stratigraphy), System, and of the Cenozoic Era or Erathem. The beginning of the Danian (and the end of the preceding Maastrichtian) is at the Cretaceous–Paleogene extinction event . The age ended , being followed by the Selandian. Stratigraphic definitions The Danian was introduced in scientific literature by Germany, German-Switzerland, Swiss geologist Pierre Jean Édouard Desor in 1847 following a study of fossils found in France and Denmark.Danien Den Store Danske Encyklopædi He identified this stage in deposits from Faxe and Møns Klint and named it after the Latin name for Denmark.

Lutetian
The Lutetian is, in the geologic timescale, a stage (stratigraphy), stage or age (geology), age in the Eocene. It spans the time between . The Lutetian is preceded by the Ypresian and is followed by the Bartonian. Together with the Bartonian it is sometimes referred to as the Middle Eocene Subepoch. Stratigraphic definition The Lutetian was named after Lutetia, the Latin language, Latin name for the city of Paris. The Lutetian Stage was introduced in scientific literature by French geologist Albert de Lapparent in 1883 and revised by A. Blondeau in 1981. The base of the Lutetian Stage is at the first appearance of the nanofossil ''Blackites inflatus'', according to an official reference profile (GSSP) established in 2011. Of two candidates located in Spain, the Gorrondatxe section was chosen.See thwebsite of Eustoquio Molinafor these candidates. The top of the Lutetian (the base of the Bartonian) is at the first appearance of calcareous nannofossils, calcareous nanoplankton s ...

Nunavut, Canada
Nunavut is the largest and northernmost territory of Canada. It was separated officially from the Northwest Territories on April 1, 1999, via the ''Nunavut Act'' and the ''Nunavut Land Claims Agreement Act'', which provided this territory to the Inuit for self-government. The boundaries had been drawn in 1993. The creation of Nunavut resulted in the first major change to Canada's political map in half a century since the province of Newfoundland (now Newfoundland and Labrador) was admitted in 1949. Nunavut comprises a major portion of Northern Canada and most of the Arctic Archipelago. Its vast territory makes it the fifth-largest country subdivision in the world, as well as North America's second-largest (after Greenland). The capital Iqaluit (formerly "Frobisher Bay"), on Baffin Island in the east, was chosen by a capital plebiscite in 1995. Other major communities include the regional centres of Rankin Inlet and Cambridge Bay. Nunavut includes Ellesmere Island in the f ...

Eureka Sound Formation
The Eureka Sound Formation is a geologic formation found in the Canadian Territory of Nunavut on Ellesmere Island, which is part of the Canadian Arctic Archipelago. The Eureka Sound Formation is Tertiary in age. History During the early Tertiary period, marine beds began forming in the Eureka Sound Formation within an area that was previously thought to be almost exclusively non-marine. This discovery indicates that this region of the Arctic had been mild, temperate, and ice-free during the early to middle Eocene, despite being well above the Arctic Circle. As of May 2014, this discovery had been restricted to the easternmost regions of the Canadian Arctic on Ellesmere Island. Because the Eureka Sound Formation contains the largest accumulation of Arctic Paleogene deposits, studying its marine deposits is key in gaining a better understanding of the early Tertiary history of the Arctic Ocean. Fossils Some fossils discovered in the Eureka Sound Formation were Paleogene land ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Clay
The London Clay Formation is a Sediment#Shores and shallow seas, marine formation (geology), geological formation of Ypresian (early Eocene Epoch, c. 54-50 million years ago) age which outcrop, crops out in the southeast of England. The London Clay is well known for its fossil content. The fossils from the lower Eocene rocks indicate a moderately warm climate, the tropical or subtropical flora. Though sea levels changed during the deposition of the clay, the habitat was generally a lush forest – perhaps like in Indonesia or East Africa today – bordering a warm, shallow ocean. The London Clay is a stiff bluish clay which becomes brown when weathered and oxidized. Nodular lumps of pyrite are frequently found in the clay layers. Pyrite was produced by microbial activity (sulfate reducing bacteria) during clay sedimentation. Once clay is exposed to atmospheric oxygen, framboidal pyrite with a great specific surface is rapidly oxidized. Acid mine drainage, Pyrite oxidation produce ...

Ouled Abdoun Basin
The Oulad Abdoun Basin (also known as the Ouled Abdoun Basin or Khouribga Basin) is a phosphate sedimentary basin located in Morocco, near the city of Khouribga. It is the largest in Morocco, comprising 44% of Morocco's phosphate reserves, and at least 26.8 billion tons of phosphate. It is also known as an important site for vertebrate fossils, with deposits ranging from the Late Cretaceous (Maastrichtian) to the Eocene epoch (Ypresian), a period of about 25 million years. Geography The Oulad Abdoun is located west of the Atlas Mountains, near the city of Khouribga. The Oulad Abdoun phosphate deposits encompass some , an area of . The Oulad Abdoun is the largest and northernmost of Morocco's major phosphate basins, which from northeast to southwest, include the Ganntour, Meskala, and Oued Eddahab (Laayoune-Baa) basins. Paleobiota The Oulad Abdoun Basin stretches from the late Cretaceous to the Eocene and contains abundant marine vertebrate fossils, including sharks, b ...
