罗平生物群

Luoping Biota

罗平生物群是目前已知多样性最为丰富的中生代海生化石库之一．代表二叠纪末生物大绝灭后早三叠世海洋生态系统的全面复苏。罗平生物群是海生动物、陆生植物以及少量陆生动物的混合群落。其中，节肢动物占主宰地位，以甲壳纲为主。还有鲎类、千足虫类等。鱼类也丰富多样，至少有二十多个种，其中大部分是新属新种。伴生化石还包括海生爬行类、双壳类、腹足类、菊石、棘皮类、腕足类、牙形石、有孔虫等。罗平生物群保存精美，种类丰富，规模庞大，堪称世界级化石宝库。是云南省继澄江动物群之后又一重大发现。

The Luoping Biota is one of the most diverse Mesozoic marine Fossil-Lagerstatten known in the world, which represents the overall revival of marine ecosystem of early Triassic after mass extinction of organisms at end of Permian. The Lnoping Biota is a mixed community of marine animals, terrestrial plants and a few terrestrial animals. The arthropod is the dominant member in the community, mainly the crustacean. Moreover, the horseshoe crab and millipede are discovered as well. The fishes are also abundant and diverse, including at least more than 20 spicies, mosdy new taxa. There are still many associated fossils, such as marine reptiles, bivalves, gastropods, ammolites, echinoderms, brachiopods, conodonts, foraminifers and plants, etc. The Luoping Biota is preserved perfectly, abundant and diverse in taxology, which can be regarded as the so-called world-rank fossil treasury. It is another important discovery after the discovery of Chengjiang Fauna in Yunnan Province.
