Paleozoic
古生代
Paleozoic (PZ) is a generation in the geological age, beginning at the isotopic age of 542 ± 0.3 million years (Ma), ending at 251 ± 0.4 Ma. Paleozoic is the first generation of the modern life, the last generation is the Neoproterozoic Neoproterozoic, the next generation is the Mesozoic. Paleozoic includes Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian. Which Cambrian, Ordovician, Silurian also known as the early Paleozoic, Devonian, Carboniferous, Permian and also known as the Late Paleozoic. Paleozoic meaning for the ancient biological age, lasted about 300 million years. For the animal world, this is an important period. It was a prelude to a Cambrian that could not be fully explained so far. The range of activities of the Cambrian animals is limited to the oceans, but during the Paleozoic continuation, some animal activities turned to dry land. In the later stages of the Paleozoic, reptiles and mammal-like animals appeared, and the Paleozoic ended with the largest known creatures so far. Early Paleozoic is called the age of invertebrates. Late Paleozoic is called fish and amphibious times. ... 古生代（Paleozoic，符号PZ）是地质时代中的一个代，开始于同位素年龄542±0.3百万年（Ma），结束于251±0.4Ma。 古生代是显生宙的第一个代，上一个代是元古宙的新元古代，下一个代是中生代。古生代包括寒武纪、奥陶纪、志留纪、泥盆纪、石炭纪、二叠纪。其中寒武纪、奥陶纪、志留纪又合称早古生代，泥盆纪、石炭纪、二叠纪又合称晚古生代。 古生代意為遠古的生物時代，持續约3亿年。對動物界來說，這是一個重要時期。它以一場至今不能完全解釋清楚的進化拉開了寒武紀的序幕。寒武紀動物的活動範圍只限於海洋，但在古生代的廷續下，有些動物的活動轉向乾燥的陸地。古生代後期，爬行動物和類似哺乳動物的動物出現，古生代以迄今所知最大的一次生物絕滅宣吿完結。 早古生代稱為無脊椎動物時代。 晚古生代稱為魚類及兩棲類時代。...
The Paleozoic geological history has been dating from about 5.7 billion years ago to 2.5 billion years ago. Duration of about 3.2 billion years. Divided into the Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian six discipline. The formation of this period called "Paleozoic." Living creatures with invertebrates as the most important. During this period, China mainly distributed marine strata. In the late formation of many coal-bearing strata. 古生代 地质历史中起自约57亿年前至25亿年前的时代。持续时间约32亿年。分为寒武纪、奥陶纪、志留纪、泥盆纪、石炭纪和二叠纪等六个纪。该时期形成的地层称“古生界”。生活的生物群以无脊椎动物为最重要。中国该时期主要分布海相地层。在中后期形成了不少含煤地层。
