摘要
首次记述了塔里木盆地西缘上丘里塔格群特马豆克晚期－阿仑尼克中期三叶虫３属４种，它们是深沟虫类Ａｋｓｕａｓｐｉｓａｋｓｕｅｎｓｉｓｇｅｎ．ｅｔｓｐ．ｎｏｖ．，栉虫类Ｍｅｇａｌａｓｐｉｄｅｓａｎｇｕｓｔｕｓｓｐ．ｎｏｖ．和Ｍ．ｓｐ．，以及１个属种不能确定的带针虫类。三叶虫相和沉积相研究表明这一动物群生活于正常和风暴浪基面之间水动力能量较高的环境，代表一种低纬度带的浅水台地组合。三叶虫具有强烈的地方性色彩。三叶虫的组成和亲缘关系分析进一步证明塔里木陆块虽然古地理位置上靠近华南陆块，但应代表独立的板块。
Abstract Specimens studied in this paper were collected in 1987 by palaeontologists of the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences and the 05 Project Administration, Bureau of Petroleum Geology of Southwest China from the measured sections in the Kalpin and Bachu areas (Text fig.1). No trilobites have been described from the Upper Qiulitag Group before; some trilobites were previously recorded by Zhang (1981) in the Kalpin area from the top part of the group, which was, however, subsequently referred to a new rock unit, the Dawangou Formation (Zhou et al., 1991).
