化石Anabarites的发现及再论玉尔吐斯组的时代归属

R EVIEW OF THE AGE OF UYIRTUS FORMATION IN THE LIGHT OF THE DISCOVERY OF Anabarites

本文根据在新疆阿克苏—乌什地区下寒武统玉尔吐斯组中发现的真正Anabarites化石,纠正了过去误定为Anabarites的几个化石,再次论证了玉尔吐斯组的时代归属.与梅树村阶可以对比.本文还阐述了玉尔吐斯组中,与小壳化石共生的高肌虫是一类较原始的最古老的甲壳类高肌虫,区别于筇竹寺阶的高肌虫.

On the basis of real Anabarites obtained from Uyirtus formation. Lower Cambrian in Aksu-Wushi area, the writer corrects the names of some fossils and once again discusses the age of this formation. The Bradoriida coexsisting with small shell fossils in Uyirtus formation is a type of primitive crustacean differing from that of Qiongzhusi member.
