Inaria
''Inaria'' is an Ediacaran fossil. It is found in the Chace Range in Australia, and the White Sea area in Russia. It has radial symmetry and has been described as a tentacle-less cnidarian. The organism had a sac-like body that resembled a cluster of garlic or conical flask in shape, with a broad bulbous base embedded in the mud, and a tube extending above the sea floor. The body cavity of ''Inaria'' was a single chamber with the inner surface of the body wall forming deep invaginations that partitioned the cavernous stomach into several septa. In its deep environment it seems that it was the only species. ''Inaria'' was found in lower shoreface muds. Australia Post issued a 50 cent stamp featuring ''Inaria'' on 21 April 2005 in a series entitled Creatures of the slime. One species known as ''Inaria karli'' was named by Jim Gehling in 1987. He published in ''A Cnidarian of Actinian-Grade from the Ediacaran Pound Subgroup of South Australia''. Alcheringa 12: 299-314. See also ...

List Of Ediacaran Genera
The existence of life, especially that of animals, before the Cambrian had long been the subject of debate in paleontology. The apparent suddenness of the Cambrian explosion had no firm explanation, and Charles Darwin himself recognized the challenge it posed for his theory of evolution. While reports of Precambrian organisms have been made since Alexander Murray's 1868 discovery of ''Aspidella'', it wasn't until the discovery of ''Charnia'' in 1956 that considerable evidence of Precambrian life had been presented. The period immediately preceding the Cambrian, the Ediacaran, is now widely accepted of containing animal life. It spans from 635 to 540 million years ago, and covers approximately 2% of Earth's history. Taxonomists have purported a total of 245 described genera from the Ediacaran, 162 of which are accepted as valid.

Ediacaran
The Ediacaran ( ) is a geological period of the Neoproterozoic geologic era, Era that spans 96 million years from the end of the Cryogenian Period at 635 Million years ago, Mya to the beginning of the Cambrian Period at 538.8 Mya. It is the last period of the Proterozoic geologic eon, Eon as well as the last of the so-called "Precambrian supereon", before the beginning of the subsequent Cambrian Period marks the start of the Phanerozoic Eon, where recognizable fossil evidence of life becomes common. The Ediacaran Period is named after the Ediacara Hills of South Australia, where trace fossils of a diverse community of previously unrecognized lifeforms (later named the Ediacaran biota) were first discovered by geologist Reg Sprigg in 1946. Its status as an official geological period was ratified in 2004 by the International Union of Geological Sciences (IUGS), making it the first new geological period declared in 120 years. Although the period took namesake from the Ediacara Hills ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albumares
''Albumares brunsae'' is a tri-radially symmetrical fossil animal that lived on the late Ediacaran seafloor. It is a member of the extinct group Trilobozoa. Etymology The generic name ''Albumares'' derives from the Latin ''Mare Album'' (White Sea). The specific name "brunsae" honors Elizabeth P. Bruns, an early 20th-century Russian geologist noted for her extensive and important research of the Upper Precambrian stratigraphy of European Russia. Occurrence Fossils of ''Albumares brunsae'' are known from deposits in the Verkhovka Formation, Syuzma River in the Onega Peninsula of the White Sea, Arkhangelsk Region, Russia. There are reports of ''Albumares'' sp. from the Rawnslay Quartzite, Flinders Ranges in South Australia, but photographs or description of these fossils have not yet been published. Description ''Albumares'' fossils are preserved as negative, low impressions on the bases of sandstone beds. The fossil exhibits circular, trefoil-like (three-lobe) form, and is ...

Ediacaran Biota
The Ediacaran (; formerly Vendian) biota is a taxonomic period classification that consists of all life forms that were present on Earth during the Ediacaran Period (). These were enigmatic tubular and frond-shaped, mostly sessile, organisms. Trace fossils of these organisms have been found worldwide, and represent the earliest known complex multicellular organisms. The term "Ediacara biota" has received criticism from some scientists due to its alleged inconsistency, arbitrary exclusion of certain fossils, and inability to be precisely defined. The Ediacaran biota may have undergone evolutionary radiation in a proposed event called the Avalon explosion, . This was after the Earth had thawed from the Cryogenian period's extensive glaciation. This biota largely disappeared with the rapid increase in biodiversity known as the Cambrian explosion. Most of the currently existing body plans of animals first appeared in the fossil record of the Cambrian rather than the Ediacara ...

Fossil
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 prin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Sea
The White Sea (; Karelian language, Karelian and ; ) is a southern inlet of the Barents Sea located on the northwest coast of Russia. It is surrounded by Karelia to the west, the Kola Peninsula to the north, and the Kanin Peninsula to the northeast. The whole of the White Sea is under Russian sovereignty and considered to be part of the internal waters of Russia.A. D. Dobrovolskyi and B. S. Zalogi"Seas of USSR.

Cnidarian
Cnidaria ( ) is a phylum under kingdom Animalia containing over 11,000 species of aquatic invertebrates found both in fresh water, freshwater and marine environments (predominantly the latter), including jellyfish, hydroid (zoology), hydroids, sea anemones, corals and some of the smallest marine parasites. Their distinguishing features are an uncentralized nervous system distributed throughout a gelatinous body and the presence of cnidocytes or cnidoblasts, specialized cells with ejectable flagella used mainly for envenomation and capturing prey. Their bodies consist of mesoglea, a non-living, jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell (biology), cell thick. Cnidarians are also some of the few animals that can reproduce both sexually and asexually. Cnidarians mostly have two basic body forms: swimming medusa (biology), medusae and sessility (motility), sessile polyp (zoology), polyps, both of which are radially symmetrical with mou ...

Erlenmeyer Flask
An Erlenmeyer flask, also known as a conical flask (British English) or a titration flask, is a type of laboratory flask with a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer (1825–1909), who invented it in 1860. Erlenmeyer flasks have wide bases and narrow necks. They may be graduated, and often have spots of ground glass or Vitreous enamel, enamel where they can be labeled with a pencil. It differs from the beaker (glassware), beaker in its tapered body and narrow neck. Depending on the application, they may be constructed from glass or plastic, in a wide range of volumes. The mouth of the Erlenmeyer flask may have a beaded lip that can be bung, stoppered or covered. Alternatively, the neck may be fitted with ground glass or other connector for use with more specialized stoppers or attachment to other apparatus. A Büchner flask is a common design modification for filtration under vacuum. Uses In chemistry The sl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australia Post
Australia Post, formally the Australian Postal Corporation and also known as AusPost, is an Australian Government-State-owned enterprise, owned corporation that provides postal services throughout Australia. Australia Post's head office is located on Swan Street in Richmond, Victoria. Australia Post is the successor of the Postmaster-General's Department, which was established at Federation of Australia, federation in 1901 to formalise colonial postal services. In 1975, the department was abolished and its postal functions were taken over by the Australian Postal Commission. The organisation's current name and structure were adopted in 1989 when it was corporatisation, made into a government-owned corporation. History Colonial Australia (pre–1901) Before colonial control of mail started in 1809, mail was usually passed on by ad hoc arrangements made between transporters, storekeepers and settlers. These arrangements were flexible, and inherently unstable. It was common f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
