十足目节肢动物化石在关岭生物群的发现

Discovery of fossil Decapod from the Guanling biota

摘要: 云南罗平岔江新江底村发现的十足目节肢动物化石产出于三叠统卡尼阶小凹组，是十足目化石在关岭生物群的首次发现，也是此类化石在中国上三叠统中首次报道。此发现增加了关岭生物群的多样性，为今后在中国三叠纪其他特异埋藏化石库中寻找更多的十足目节肢动物化石提供了新的线索。

Abstract: This paper reports a new specimen of decapod from Xinjiangdi Village of Chajiang Town, Luoping County, Yunnan Province. The new material comes from Triassic (Carnian) Xiawa Formation. It is the first discovery of the decapod from the Guan-ling biota, and also the first report from the Upper Triassic strata in China. The new findings increase the diversity of the Guanling bi-ota and provide new clue for further discovery of decapod in other Triassic exceptional lagerstäten from China in the future.
