Coenites
''Coenites'' is an extinct genus of prehistoric corals in the family Coenitidae. ''C dublinensis'' occurs in the Columbus Limestone, a mapped bedrock unit consisting primarily of fossiliferous limestone, and it occurs in Ohio, Pennsylvania, and Virginia in the United States, and in Ontario, Canada.

Columbus Limestone
The Columbus Limestone is a mapped bedrock unit consisting primarily of fossiliferous limestone, and it occurs in Ohio, Pennsylvania, and Virginia in the United States, and in Ontario, Canada. Description Depositional environment The depositional environment was most likely shallow marine. Stratigraphy The Columbus conformably overlies the Lucas Dolomite in northeastern Ohio, and unconformably overlies other dolomite elsewhere. It unconformably underlies the Ohio Shale in northwestern Ohio and the Delaware Limestone in eastern Ohio. Its members include: Bellepoint, Marblehead, Tioga Ash Bed, Venice, Delhi, Klondike, and East Liberty. Notable Exposures *The type section is located in Columbus, Ohio. *The glacial grooves on Kelleys Island are cut into the Columbus Limestone. It is also quarried there. *An exposure in Ontario is located at Ingersoll, Ontario. Fossils The Columbus Limestone contains brachiopods, trilobites, bryozoans, mollusks, corals, stromatoporoids and echi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Prehistoric Hexacoral Genera
This list of prehistoric hexacorals (Scleractinia) is an attempt to create a comprehensive listing of all genera that have ever been included in the hexacorallia which are known from the fossil record. This list excludes purely vernacular terms. It includes all commonly accepted genera, but also genera that are now considered invalid, doubtful ('' nomina dubia''), or were not formally published (''nomina nuda''), as well as junior synonyms of more established names, and genera that are no longer considered scleractinia. Naming conventions and terminology Naming conventions and terminology follow the International Code of Zoological Nomenclature. Technical terms used include: * Junior synonym: A name which describes the same taxon as a previously published name. If two or more genera are formally designated and the type specimens are later assigned to the same genus, the first to be published (in chronological order) is the senior synonym, and all other instances are junior sy ...

Karl Eichwald
Karl Eduard von Eichwald (russian: Эдуард Иванович Эйхвальд, ''Eduard Ivanovich Eykhvald''; 4 July 1795, in Mitau, Courland Governorate – 10 November 1876, in Saint Petersburg) was a Baltic German geologist, physician, and Natural history, naturalist, who worked in Russian Empire, Russia. Career Eichwald was a Baltic German born at Mitau in Courland Governorate. He became a doctor of medicine and professor of zoology in Kazan in 1823; four years later professor of zoology and comparative anatomy at Vilnius; in 1838 professor of zoology, mineralogy and medicine at St. Petersburg; and finally, professor of palaeontology in the institute of mining, mines in that city. He travelled much in the Russian Empire, and was a keen observer of its natural history and geology. He died at St. Petersburg. Eichwald was a supporter of Darwinism. Works His published works include ''Reise auf dem Caspischen Meere und in den Caucasus'', 2 vols. (Stuttgart and Tübingen, 1834 ...

Prehistoric Hexacorallia Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tabulata
Tabulata, commonly known as tabulate corals, are an order of extinct forms of coral. They are almost always colonial, forming colonies of individual hexagonal cells known as corallites defined by a skeleton of calcite, similar in appearance to a honeycomb. Adjacent cells are joined by small pores. Their distinguishing feature is their well-developed horizontal internal partitions (''tabulae'') within each cell, but reduced or absent vertical internal partitions ( ''septa''). They are usually smaller than rugose corals, but vary considerably in shape, from flat to conical to spherical. Around 300 species have been described. Among the most common tabulate corals in the fossil record are ''Aulopora'', ''Favosites'', ''Halysites'', ''Heliolites'', ''Pleurodictyum'', ''Sarcinula'' and '' Syringopora''. Tabulate corals with massive skeletons often contain endobiotic symbionts, such as cornulitids and ''Chaetosalpinx''. Like rugose corals, they lived entirely during the Paleozoi ...

Paleontology In New Jersey
The location of the state of New Jersey Paleontology in New Jersey refers to paleontological research in the US state of New Jersey. The state is especially rich in marine deposits. During the Precambrian, New Jersey was covered by a shallow sea that was home to stromatolite forming bacteria. During the early part of the Paleozoic, the state was still covered by the sea, which was home to creatures like brachiopods and trilobites. By the Silurian, the northern part of the state was home to a river system. Sea levels rose and fell throughout the remainder of the state's Paleozoic rock record. There are no local rocks of Carboniferous or Permian age. During the Triassic, the state was a terrestrial ecoregion. Local lakes were home to the crustacean ''Cyzicus'' and the coelacanth ''Diplurus''. On land, dinosaurs left behind footprints, and continued to do so into the Jurassic. A sea rose over southern New Jersey during the Cretaceous. Invertebrates, plesiosaurs and turtles li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleozoic Life Of Ontario
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 even ...
