Pentamerus Range
The Pentamerus Range ( da, Pentamerus Bjerge) is a mountain range in far northwestern Greenland. Administratively this range is part of Avannaata municipality. The area of the range is uninhabited.Google Earth This mountain chain was named after the Pentamerus fossils dating back to the Lower Silurian that have been found in it. Geography The Pentamerus Range is an up to almost 1,000 m high mountain range in Daugaard-Jensen Land. It runs roughly from northeast to southwest. See also *List of mountain ranges of Greenland *Peary Land Group The Peary Land Group is a geologic group in Greenland. It preserves fossils dating back to the Silurian period.

Gall Mite
Eriophyidae is a family of more than 200 genera of mites, which live as plant parasites, commonly causing galls or other damage to the plant tissues and hence known as gall mites. About 3,600 species have been described, but this is probably less than 10% of the actual number existing in this poorly researched family. They are microscopic mites and are yellow to pinkish white to purplish in color. The mites are worm like, and have only two pairs of legs. Their primary method of population spread is by wind. They affect a wide range of plants, and several are major pest species causing substantial economic damage to crops. Some species, however, are used as biological agents to control weeds and invasive plant species. Notable species Notable species in this family include: *'' Abacarus hystrix'', the cereal rust mite *'' Abacarus sacchari'', the sugarcane rust mite *'' Acalitus essigi'', the redberry mite, which affects blackberries *''Aceria chondrillae'', the chondrilla ga ...

Pentamerida
Pentamerida is an order of biconvex, impunctate shelled, articulate brachiopods that are found in marine sedimentary rocks that range from the Middle Cambrian through the Devonian.Moore, Lalcker and Fischer, 1952, Invertebrate Fossils, McGraw-Hill Pentamerids are characterized by a short hinge line where the two valves articulate, inner areas above the hinge line that slope inwardly from the beak of each valve, and a well-developed spondylium on the pedicle valve. The spondylium is a raised platform for muscle attachment found in the middle of the interior pedicle valve, generally toward the hinge and beak. The pedicle valve is the one that the pedicle, or hold-fast stalk, attaches to. The brachidia, which hold the lophophore, the ciliated feeding arms, are looped, as in the Orthida. The Short hinge line helps distinguish the pentamerids from the ancestral orthids from which they are obviously derived. The hinge line is not as short as found in the Rhynchonellida or Athyridida ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jeffersonville Limestone
The Devonian Jeffersonville Limestone is a mapped bedrock unit in Indiana and Kentucky. It is highly fossiliferous. Description The Jeffersonville is a coarse grained, dark gray, thick bedded, fossiliferous limestone.Butts, Charles, 1915, Geology and mineral resources of Jefferson County, Kentucky: Kentucky Geological Survey eport 4th series, v. 3, pt. 2, 270 p. R. D. Perkins (1963) divided the Jeffersonville into five zones based on petrology and fossil content,Ronald D. Perkins, 1963, Petrology of the Jeffersonville Limestone (Middle Devonian) of Southeastern Indiana: Geological Society of America Bulletin (1963), 74(11):1335-135abstract/ref> and these are summarized below (in stratigraphic order): * ''Paraspirifer acuminatus'' zone (top) * fenestrate bryozoan-brachiopod zone * ''Brevispirifer gregarius'' zone * ''Amphipora''-zone * Coral zone (base, overlies Geneva Dolomite or Louisville Limestone) Fossils The Jeffersonville Limestone is well known for its fossils, including ...

Paleozoic Life Of Manitoba
The Paleozoic (or Palaeozoic) Era is the earliest of three geologic eras of the Phanerozoic Eon. The name ''Paleozoic'' ( ;) was coined by the British geologist Adam Sedgwick in 1838 by combining the Greek words ''palaiós'' (, "old") and ''zōḗ'' (), "life", meaning "ancient life" ). It is the longest of the Phanerozoic eras, lasting from , and is subdivided into six geologic periods (from oldest to youngest): # Cambrian # Ordovician # Silurian # Devonian # Carboniferous # Permian The Paleozoic comes after the Neoproterozoic Era of the Proterozoic Eon and is followed by the Mesozoic Era. The Paleozoic was a time of dramatic geological, climatic, and evolutionary change. The Cambrian witnessed the most rapid and widespread diversification of life in Earth's history, known as the Cambrian explosion, in which most modern phyla first appeared. Arthropods, molluscs, fish, amphibians, reptiles, and synapsids all evolved during the Paleozoic. Life began in the ocean but eve ...

Silurian Brachiopods
The Silurian ( ) is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the shortest period of the Paleozoic Era. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods (myriapods, arachnids and hexapods) became fully terrestrialized. A significant evolutionary milestone durin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
