When was the carbon period?
The Carboniferous Period (Meaning "Carbon-Bearing") is and Geological Time Period WHICH LASTED ABOUT 60 Million Years, Between the Devonian Period 340 Million Years Ago (Mya) and the Permian Period 280 Mya. Swamps and Forests Flourished, Producting an Excess of Atmospheric Oxygen Up To 80% Higher Than Today's Levels, and Massive Quantities of Decaying Organic Matter. This organic matter eventually turned to coal for millions of years of pressure from the soil and rocks above it, and above it is responsible for the existence of large coal deposits in England and Western Europe. These coal beds, coming from the carbon period, powered the first industrial revolution and today are mined for coal. It was created when several smaller continents were pushing into each other, leading to Appalachians, Atlas and Urals. Panga was so great that its center was very dry, but the coastal areas flourished with a large and exotic flora and fauna. During the carbon period it was possible for an animal toAta migrated all the way from the North Pole to the South Pole. The excess oxygen due to floral overgrowth led to gigantism in some amphibians and insects, including the largest insects ever developed, the predecessor of the dragon, with a span of 73 cm (29 inches). Brachiopods were common during the Carbonian period and ancient species, such as trilobit , began to die.
Large carbon deposits produced during the Carbon period were caused by two main factors: the development of the bark on the trees in the form of an organic polymer lignin ; And lower sea levels, allowing forests and swamps grow on lowlands that would have been flooded before. The ligninby was the decisive evolutionary advantage for many trees, protected them from the outside world and made them less digestible for animals. Bacteria and animals took many millions of years to evolve, which could effectively spend lignin, causing large nAcquisition of organic material on the ground, sometimes higher than 2m (6.5 ft) high. Lignin still accounts for a quarter to half of the wood when it is dry. It is formed in the plant by removing water from certain sugars.
TheCarbonian period can be divided into a series of shorter subperiiod, each about 10 million years for duration: tournament, Viséan, Serpukhovian, Bashkirian, Moscovian, Kasimovian and Gzhelian period.
