Primocandelabrum
''Primocandelabrum'' is a genus of rangeomorph known from the Avalon-type Ediacaran biota. It makes up the brunt of some bedding plane assemblages. ''Primocandelabrum'' was described by Hofmann, O'Brien, and King in 2008. Diversity Fossil specimens of Primocandelabrum from Charnwood Forest: * Primocandelabrum aelfwynnia Kenchington & Wilby, 2017 * Primocandelabrum boyntoni Kenchington & Wilby, 2017 * Primocandelabrum aethelflaedia Kenchington & Wilby, 2017 Fossil specimens of Primocandelabrum from Bonavista Peninsula: * Primocandelabrum Hiemaloranum Hofmann, 2008 * Primocandelabrum sp. Hofmann, 2008 Etymology The fossils are thus named since it resembles candelabra, giving it its signature genus name.

Hylaecullulus
''Hylaecullulus fordi'' is a species of Ediacaran petalonamid from the Charnwood Forest of Leicestershire, England that serves as an important rangeomorph because of its multifoliate anatomy, known from its fossils. Its overall body plan is similar to that of a goblet, from which its name, ''Hylaecullulus'', derives. Etymology The name ''Hylaecullulus fordi'' derives from its occurrence within Charnwood Forest: , (which means 'from the woods' in Ancient Greek and , which means 'small goblet' in that language. The name of the type species, "fordi", was given to honour Trevor Ford, who made important contributions to the Ediacaran fauna. Discovery ''Hylaecullulus fordi'' was discovered in the hilly tract of Charnwood Forest in 2018 by a team led by C. G. Kenchington. This team found six well-preserved fossils, all of which had fossilised with the lateral view of the animal visible, from the top of the Bradgate Formation of the Maple Group. Although two specimens out of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rangeomorpha
The rangeomorphs are a form taxon of frondose Ediacaran Ediacaran biota, fossils that are united by a similarity to ''Rangea''. Some researchers, such as Pflug and Narbonne, suggest that a natural taxon Rangeomorpha may include all similar-looking fossils. Rangeomorphs appear to have had an effective reproductive strategy, based on analysis of the distribution pattern of ''Fractofusus misrai'', which consisted of sending out a waterborne asexual propagule to a distant area, and then spreading rapidly from there, just as plants today spread by stolons or runners. Rangeomorphs are a key part of the Ediacaran biota, which survived about 30 million years, until the base of the Cambrian, which was . They were especially abundant in the early Ediacaran Mistaken Point assemblage found in Newfoundland (island), Newfoundland.

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Petalonamae
The petalonamids (Petalonamae) are an extinct group of archaic animals typical of the Ediacaran biota, also called frondomorphs, dating from approximately 635 million years ago to 516 million years ago. They are benthic and motionless animals, that have the shape of leaves, fronds (frondomorphic), feathers or spindles and were initially considered algae, octocorals or sea pens. It is now believed that there are no living descendants of the group, which shares a probable relation to the Ediacaran animals known as Vendozoans. It is considered that the organisms were fluffy at least in appearance, as if "inflatable." They are particularly difficult to classify phylogenetically. Lacking mouths, intestines, reproductive organs, and with no preserved evidence of internal structures, these organisms' existence is very strange by current standards. The most widely accepted hypothesis is that they could suck nutrients from the water around them by osmosis. The fronds were composed of bra ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ediacaran Biota
The Ediacaran (; formerly Vendian) biota is a Taxonomy (biology), taxonomic period classification that consists of all life forms that were present on Earth during the Ediacaran Period (). These were composed of enigmatic tubular and frond-shaped, mostly sessility (zoology), sessile, organisms. Trace fossils of these organisms have been found worldwide, and represent the earliest known complex multicellular organisms. 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 Snowball Earth, 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, fossil record of the Cambrian rather than the Ediacaran. For macroorganisms, the Cambrian biota appears to have almost completely replaced the organisms that dominate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charnwood Forest
Charnwood Forest is a hilly tract in north-western Leicestershire, England, bounded by Leicester, Loughborough and Coalville. The area is undulating, rocky and picturesque, with barren areas. It also has some extensive tracts of woodland; its elevation is generally and upwards, the area exceeding this height being about . The highest point, Bardon Hill, is . On its western flank lies an abandoned coalfield, with Coalville and other former mining villages, now being regenerated and replanted as part of the National Forest. The M1 motorway, between junctions 22 and 23, cuts through Charnwood Forest. The hard stone of Charnwood Forest has been quarried for centuries, and was a source of whetstones and quern-stones. The granite quarries at Bardon Hill, Buddon Hill and Whitwick supply crushed aggregate to a wide area of southern Britain. The forest is an important recreational area with woodland walks, noted for their displays of bluebells in the early spring, rock climbing ...

Bonavista Peninsula
The Bonavista Peninsula is a large peninsula on the east coast of the island of Newfoundland in the Canadian province of Newfoundland and Labrador. It consists of 50 incorporated towns/unincorporated communities which have a population of 12,176 as of the 2016 Canadian Census. Bonavista is the largest population centre on the peninsula. The peninsula runs 85 km northeast from a 19 km wide isthmus and measures between 15–40 km in width. It separates Bonavista Bay in the north from Trinity Bay to the south. Geography Starting at the Trinity Bay side it commences at the northeastern part of the bay at Shoal Harbour, immediately north of Clarenville. Continuing east the peninsula's south shore includes the communities of Trinity and Catalina, with Port Rexton in Robinhood Bay between them, ending at its easternmost tip at Cape Bonavista. The north shore of the peninsula includes the communities of Bonavista, Summerville and Musgravetown to Port Blandford. The h ...

Candelabra
A candelabra (plural candelabras) or candelabrum (plural candelabra or candelabrums) is a candle holder with multiple arms. Although electricity has relegated candleholders to decorative use, interior designers continue to model light fixtures and lighting accessories after candelabra and candlesticks. Accordingly, the term candelabra has entered common use to describe small-based light bulbs used in chandeliers and other lighting fixtures made for decoration as well as lighting. In Judaism and in the Philippine religion Iglesia ni Cristo, the menorah is a special kind of candelabrum. The Candelabra is also used in certain Eastern Catholic and Eastern Orthodox church architecture and liturgy by bishops as the Trikiridikiri. Singular and plural This word originally came from Latin, in which ''candelabrum'' is the singular form and ''candelabra'' is the plural. Over time, English usage changed so that ''candelabra'' as the singular and ''candelabras'' as the plural is no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proterozoic Animals
The Proterozoic () is a geological eon spanning the time interval from 2500 to 538.8million years ago. It is the most recent part of the Precambrian "supereon". It is also the longest eon of the Earth's geologic time scale, and it is subdivided into three geologic eras (from oldest to youngest): the Paleoproterozoic, Mesoproterozoic, and Neoproterozoic. The Proterozoic covers the time from the appearance of oxygen in Earth's atmosphere to just before the proliferation of complex life (such as trilobites or corals) on the Earth. The name ''Proterozoic'' combines two forms of ultimately Greek origin: meaning 'former, earlier', and , 'of life'. The well-identified events of this eon were the transition to an oxygenated atmosphere during the Paleoproterozoic; the evolution of eukaryotes; several glaciations, which produced the hypothesized Snowball Earth during the Cryogenian Period in the late Neoproterozoic Era; and the Ediacaran Period (635 to 538.8 Ma) which is characterized b ...
