Paleontology In Saskatchewan
The Fauna of Saskatchewan include several diverse land and aquatic animal species. From the multiplicity of invertebrates and vertebrates, two have been chosen as symbols of Saskatchewan. Cenozoic vertebrate fossils reveal the Geology of Saskatchewan, geological evolution of the Interior Plains, interior plains and its prehistoric biogeography. Today, Saskatchewan's ecosystems range from the Subarctic, sub-arctic tundra of the Canadian Shield in north Saskatchewan to aspen parkland, the Mid-Continental Canadian forests in the centre of the province and grassland prairie. Fauna inhabit areas unique to their own specific and varied breeding, foraging and nesting requirements. With a large land and water area, and small population density, the Flora of Saskatchewan, ecoregions of Saskatchewan provide important habitat for many animals, both endangered and not. Naturalists observing wildlife have enumerated shrinking and growing wildlife populations. They advocate programs and method ...

White-tailed Deer
The white-tailed deer (''Odocoileus virginianus''), also known Common name, commonly as the whitetail and the Virginia deer, is a medium-sized species of deer native to North America, North, Central America, Central and South America. It is the most widely-distributed mainland ungulate herbivore in the Americas; coupled with its natural predator, the Cougar, mountain lion (''Puma concolor''), it is one of the most widely-distributed terrestrial mammal species in the Americas and the world. Highly adaptable, the various subspecies of white-tailed deer inhabit many different ecosystems, from arid grasslands to the Amazon basin, Amazon and Orinoco Basin, Orinoco basins; from the Pantanal and the Llanos to the high-elevation terrain of the Andes. Globally, the white-tailed deer has been introduced (primarily for Trophy hunting, sport hunting) to New Zealand, the Greater Antilles of the Caribbean (Cuba, Jamaica, Hispaniola, and Puerto Rico), and some countries in Europe (mainly the Cz ...

Aspen Parkland
Aspen parkland refers to a very large area of ecotone, transitional biome between prairie and boreal forest in two sections, namely the Peace River Country of northwestern Alberta crossing the border into British Columbia, and a much larger area stretching from central Alberta, all across central Saskatchewan to south central Manitoba and continuing into small parts of the US states of Minnesota and North Dakota. Aspen parkland consists of groves of aspen, Populus, poplar and spruce, interspersed with areas of prairie grasslands, also intersected by large stream and river valleys lined with aspen-spruce forests and dense shrubbery. This is the largest boreal-grassland transition zone in the world and is a zone of constant competition and tension as prairie and woodlands struggle to overtake each other within the parkland. This article focuses on this biome in North America. Similar biomes also exist in Russia north of the steppes (forest steppe) and in northern Canada. Definitio ...

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Miocene
The Miocene ( ) is the first epoch (geology), 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 Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
Paleocene
The Paleocene ( ), or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by an asteroid impact (Chicxulub impact) and possibly volcanism (Deccan Traps), marked the beginning of the Paleocene and killed off 75% of species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. ...

Merycoidodon BW
''Merycoidodon'' (" ruminating teeth") is an extinct genus of herbivorous artiodactyl of the family Merycoidodontidae, more popularly known by the name ''Oreodon'' ("hillock teeth"). It was endemic to North America during the Middle Eocene to Middle Miocene (46—16 mya) existing for approximately . Taxonomy Most researchers in paleobiology and paleontology now use the antecedent genus ''Merycoidodon'' to refer to this Oligocene epoch oreodont, even though it was once widely known by the younger synonym of ''Oreodon''. Taxonomically speaking, ''Merycoidodon'' belongs to the family Merycoidodontidae (once known as "Oreodontidae"), a group of artiodactyls related to camels that were endemic to North America. Its ancestors date back to the Eocene and its last descendants are known from the end of the Miocene, so that oreodonts, broadly speaking, lived throughout most of the Paleogene. Morphology ''Merycoidodon'' would have somewhat resembled a pig in appearance, but had a lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sharp-tailed Grouse
The sharp-tailed grouse (''Tympanuchus phasianellus''), also known as the sharptail or fire grouse, is a medium-sized prairie grouse. One of three species in the genus ''Tympanuchus'', the sharp-tailed grouse is found throughout Alaska, much of Northern Canada, Northern and Western Canada, and parts of the Western United States, Western and Midwestern United States. The sharp-tailed grouse is the List of Canadian provincial and territorial symbols, provincial bird of the Canadian province of Saskatchewan. Taxonomy In 1750 the English naturalist George Edwards (naturalist), George Edwards included an illustration and a description of the sharp-tailed grouse in the third volume of his ''A Natural History of Uncommon Birds''. He used the English name "The Long-tailed Grous from Hudson's-Bay". Edwards based his hand-coloured etching on a preserved specimen that had been brought to London from Hudson Bay by James Isham. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct.
