Seriola Sanctaebarbarae
''Seriola sanctaebarbarae'' (named after the city of Santa Barbara) is an extinct species of marine ray-finned fish known from the Late Miocene of California, USA. It is known from the presumably Tortonian-aged diatomite deposits of the Monterey Formation near Lompoc. It was a close relative of modern amberjacks, belonging to the same genus as them (''Seriola''). Its morphology differs from that of the modern California yellowtail (''S. dorsalis'') that now occupies the California coast, and resembles that of the older species '' S. prisca'' from the Early Eocene of Italy and '' S. natgeosoc'' from the Middle Eocene (Bartonian) of North Caucasus, Russia. The species ''Hemicaranx archaeus'', also found in the same formation, appears to be synonymous with it. It was a large species that could grow up to .

Late Miocene
The Late Miocene (also known as Upper Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages. The Tortonian and Messinian stages comprise the Late Miocene sub-epoch, which lasted from 11.63 Ma (million years ago) to 5.333 Ma. The evolution of ''Homo'' The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') were the first groups to split from the line leading to the hominins, including humans, then gorillas (genus ''Gorilla''), and finally chimpanzees and bonobos (genus ''Pan (genus), Pan''). The splitting date between hominin and chimpanzee lineages is placed by some between 4 and 8 million years ago, that is, during the Late Miocene.

California Yellowtail
''Seriola dorsalis'', the California yellowtail, is a species of ray-finned fish of the family Carangidae. This species is also known by several alternate names, such as yellowtail jack, amberjack, forktail, mossback, white salmon and yellowtail tunis or tunaCalifornia Yellowtail Retrieved August 2009 or by its Spanish name jurel. Although previously thought to belong to ''S. lalandi'', recent genetic analysis distinguished California yellowtail (''S. dorsalis'') as a distinct species from the yellowtail amberjack (''S. lalandi''). The California yellowtail is differentiated from yellowtail amberjack as they differ in range. The yellowtail amberjack is found farther south in the Pacific Ocean.

Fossil Taxa Described In 1921
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 ...

Miocene Fish Of North America
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 followed the Oligocene and preceded 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 distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and hominoids into Eurasia. During the late Miocene, the connections between the A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tortonian Life
The Tortonian is in the geologic time scale an age or stage of the late Miocene that spans the time between 11.608 ± 0.005 Ma and 7.246 ± 0.005 Ma (million years ago). It follows the Serravallian and is followed by the Messinian. The Tortonian roughly overlaps with the regional Pannonian Stage of the Paratethys timescale of Central Europe. It also overlaps the upper Astaracian, Vallesian and lower Turolian European land mammal ages, the upper Clarendonian and lower Hemphillian North American land mammal ages and the upper Chasicoan and lower Huayquerian South American land mammal ages. Definition The Tortonian was introduced by Swiss stratigrapher Karl Mayer-Eymar in 1858. It was named after the Italian city of Tortona in the Piedmont region. The base of the Tortonian Stage is at the last common appearance of calcareous nanoplankton '' Discoaster kugleri'' and planktonic foram '' Globigerinoides subquadratus''. It is also associated with the short normal polarized magnetic c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Caucasus
The North Caucasus, or Ciscaucasia, is a subregion in Eastern Europe governed by Russia. It constitutes the northern part of the wider Caucasus region, which separates Europe and Asia. The North Caucasus is bordered by the Sea of Azov and the Black Sea to the west, the Caspian Sea to the east, and the Caucasus Mountains to the south. The region shares land borders with the countries of Georgia (country), Georgia and Azerbaijan in the South Caucasus. Located in the southern part of the region, Mount Elbrus is the List of European ultra-prominent peaks, tallest peak in Europe. Krasnodar is the List of cities and towns in Russia by population, most populous among the urban area, urban centres in the region. The North Caucasus came under Russian control in the 19th century, following the Caucasian War between the Russian Empire and the various regional powers. The territory is the Southern Russia, southernmost portion of Russia and is divided between a number of Republics of Russia, ...

Bartonian
The Bartonian is, in the International Commission on Stratigraphy's (ICS) geologic time scale, a stage or age in the middle of the Eocene Epoch or Series. The Bartonian Age spans the time between . It is preceded by the Lutetian and is followed by the Priabonian Age. Stratigraphic definition The Bartonian Stage was introduced by Swiss stratigrapher Karl Mayer-Eymar in 1857. The name derives from the Barton Group, a lithostratigraphic unit from the south English Hampshire Basin, which in turn derived its name from the local coastal village Barton-on-Sea (part of New Milton) in southern England. The distinction between group and stage was made in the second part of the 20th century, when stratigraphers saw the need to distinguish between litho- and chronostratigraphy. The base of the Bartonian is at the first appearance of the calcareous nanoplankton species ''Reticulofenestra reticulata''. In 2009, an official reference profile (GSSP) for the base of the Bartonian had not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Eos, Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seriola Natgeosoc
''Seriola'' is a genus of ray-finned fish, with many species commonly known as amberjacks. Nine extant species are currently recognized, although these were formerly split into many more. Also, several species are currently placed in several other genera of the Carangidae that were originally described under ''Seriola''. They are a large, carnivorous finfish popularly known for the firm texture and rich flavour of their flesh, which make them an ideal fish for aquaculture. Because specimens caught can weigh up to , and are powerful swimmers and hunters, they are also highly prized by sport fisherman. Most ''Seriola'' species are either benthic, demersal, or pelagic, and can be found down to 200 m. All 9 species cover most of the globe in terms of distribution, usually in coastal waters. Most are shown to be pelagic spawners, releasing eggs into the open ocean habitat until hatching, and they do this through dioecious, external reproduction. Most ''Seriola'' species are found in ...

Ypresian
In the geologic timescale the Ypresian is the oldest age (geology), age or lowest stage (stratigraphy), stratigraphic stage of the Eocene. It spans the time between , is preceded by the Thanetian Age (part of the Paleocene) and is followed by the Eocene Lutetian Age. The Ypresian is consistent with the Lower Eocene (Early Eocene). Events The Ypresian Age begins during the throes of the Paleocene–Eocene Thermal Maximum (PETM). The Fur Formation in Denmark, the Messel shales in Germany, the Oise amber of France and Cambay amber of India are of this age. The Eocene Okanagan Highlands are an uplands subtropical to temperate series of lakes from the Ypresian. The Ypresian is additionally marked by another warming event called the Early Eocene Climatic Optimum (EECO). The EECO is the longest sustained warming event in the Cenozoic record, lasting about 2–3 million years between 53 and 50 Ma. The interval is characterized by low oxygen-18 isotopes, high levels of atmospheric pCO2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seriola Prisca
''Seriola prisca'' (''prisca'' being Latin for "ancient") is an Extinction, extinct species of prehistoric marine Actinopterygii, ray-finned fish from the Eocene. Complete fossil specimens are known from the famous Ypresian, Early Eocene-aged Monte Bolca site of Italy. It was a close relative of modern amberjacks, belonging to the same genus as them (''Seriola''), and is one of the oldest known members of the genus. Due to its age and it belonging to an extant genus, it has often been used to provide a minimum age constraint for divergence of the Carangidae, carangid radiation. It closely resembles and may be related to the extinct species ''Seriola natgeosoc, S. natgeosoc'' from the Bartonian of North Caucasus, Russia. It was first erroneously identified in 1796 by Giovanni Serafino Volta as a fossil specimen of the extant "''Scomber pelagicus''" (now synonymized with the modern mahi-mahi). In 1834, it was described by Louis Agassiz as ''Lichia prisca'', who considered it an ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
