Information: - Sinotubulites is a genus of small , tube - shaped shelly fossils from the Ediacaran period . It is often found in association with Cloudina . Its tube has a '' tube - in - tube '' structure composed of several thin layers . It bears prominent longitudinal sculptures and / or irregular rings , which were formed by the wrinkles of tube layers , and weaken gradually towards the inner layers . The organism probably had a sessile life - style , lying on the sea floor . Sinotubulites and Cloudina ( discovered in 1972 ) are currently the two earliest known fossils of organisms that mineralized shells when alive , and are often found in the same fossil beds . It is remarkable that Cloudina specimens often have tiny holes bored in them , which are attributed to predators , while no such borings have been found in Sinotubulites . This suggests that Sinotubulites had evolved features that made it a much less attractive target than Cloudina . As a result , both organisms are important in analyses of the Cambrian explosion , as predation and the appearance of mineralised components are often cited as possible causes of the '' explosion '' . - Ediacara Hills are a range of low hills in the northern part of the Flinders Ranges of South Australia, around north of Adelaide. The area has many old copper and silver mines from mining activity during the late 19th century. The hills also contain fossils of early multicellular life forms, the Ediacaran biota (lagerstatte), and have given their name to the Ediacaran geological period. - The Ediacaran Period, spans 94 million years from the end of the Cryogenian Period 635 million years ago (Mya), to the beginning of the Cambrian Period 541 Mya. It marks the end of the Proterozoic Eon, and the beginning of the Phanerozoic Eon. It is named after the Ediacara Hills of South Australia. - A genus (genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. - The Cambrian Period (or ) was the first geological period of the Paleozoic Era, of the Phanerozoic Eon. The Cambrian lasted 55.6 million years from the end of the preceding Ediacaran Period 541 million years ago (mya) to the beginning of the Ordovician Period mya. Its subdivisions, and its base, are somewhat in flux. The period was established (as Cambrian series) by Adam Sedgwick, who named it after Cambria, the Latinised form of "Cymru", the Welsh name for Wales, where Britain's Cambrian rocks are best exposed. The Cambrian is unique in its unusually high proportion of lagerstatte sedimentary deposits, sites of exceptional preservation where "soft" parts of organisms are preserved as well as their more resistant shells. As a result, our understanding of the Cambrian biology surpasses that of some later periods. - Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus. - South Australia (abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories. It has a total of 1.7 million people, and its population is the most highly centralised of any state in Australia, with more than 75 percent of South Australians living in the capital, Adelaide, or its environs. Other population centres in the state are relatively small. - In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs. What is the relationship between 'sinotubulites' and 'animal'?
