羅平生物群是目前已知多樣性最為豐富的中生代海生化石庫之一，代表二疊紀(jì)末生物大絕滅后早三疊世海洋生態(tài)系統(tǒng)的全面復(fù)蘇。

羅平生物群是海生動(dòng)物、陸生植物以及少量陸生動(dòng)物的混合群落。其中，節(jié)肢動(dòng)物占主宰地位，以甲殼綱為主，還有鱟類、千足蟲類等。魚類也豐富多樣， 至少有二十多個(gè)種，其中大部分是新屬新種。伴生化石還包括海生爬行類、雙殼類、腹足類、菊石、棘皮類、腕足類、牙形石、有孔蟲等。羅平生物群保存精美，種類豐富，規(guī)模龐大， 堪稱世界級(jí)化石寶庫，是云南省繼澄江動(dòng)物群之后又一重大發(fā)現(xiàn)。

羅平生物群由中國地質(zhì)調(diào)查局成都地調(diào)中心進(jìn)行1：50 000區(qū)調(diào)時(shí)發(fā)現(xiàn)。首發(fā)地位于云南省羅平縣城東南12km羅雄鎮(zhèn)大洼子村。生物化石賦存于中三疊統(tǒng)世（安尼期）關(guān)嶺組二段。

Luoping Biota

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 Luoping 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, mostly 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.

The Luoping Biota is discovered by Chengdu Geological Survey Center, China Geological Survey Bureau, in 1: 50 000 regional survey.The first discovery place is Dawazi Village in Luoxiong Town, 12km SE of Luoping County town.The fossils are occurred in Member 2 of the Guanling Formation,Middlle Triassic(Anlsian)
