The first discovery of anomalocaridid appendages from the Balang Formation (Cambrian Series 2) in Hunan, China

Abstract

Liu, Q., 2013. The first discovery of anomalocaridid appendages from the Balang Formation (Cambrian Series 2) in Hunan, China. Alcheringa 37, 1–6. ISSN 0311-5518.

This study reports the first discovery of anomalocaridid appendages from the lower part of the Balang Formation (Cambrian Series 2) in Paiwu, northwestern Hunan Province, China. The material includes Anomalocaris sp., a representative of a genus recognized in most of the major Cambrian Lagerstätten, and Peytoia sp. cf. P. nathorsti Walcott, 1911, representing the first record of the ‘Appendage F’-type (Hurdia/Peytoia-type) frontal appendages from China. These new discoveries increase our knowledge of the diversity of anomalocaridids in China.

中国湖南Balang组(寒武纪系列2)anomalocaridid附肢 的首次发现
