摘要/Abstract

摘要： 下寒武统双瓣壳节肢动物高肌虫朵氏小昆明虫是云南省澄江化石库中最常见的物种之一，新发现朵氏小昆明虫的携卵标本显示了在5.2亿年前的寒武纪动物就出现了孵育的繁殖策略和生态学上的K-选择策略，是对寒武纪海洋软泥质基底的响应。

Abstract: The Bivalved bradoriid arthropod Kunmingella douvillei is one of the most species from the Chengjiang Lagersttte in the Lower Cambrian. Kunmingella douvillei of newly discovered egg-bearing showed that animals appeared reproductive strategy of incubation and K-selection strategy in ecology in the Cambrian from 520 million years ago. It is response to soft clay base of the Cambrian Marine.
