封面故事：中华侏罗兽(左) 和八臂仙母虫 (右)的标本及复原图。中华侏罗兽是目前世界上发现的最古老的真兽类哺乳动物, 代表了早期哺乳动物演化的一个新里程碑。八臂仙母虫确定属于原始类群的栉水母动物, 为追溯早期多细胞生物的起源提供了化石依据。这项由中国地质科学院地质研究所季强、吕君昌、唐烽三个团队分别在古生物演化领域取得的研究成果，共同当选2011年度中国地质科学院十大科技进展，排名第六。详见本期第715-729页。（图片提供：季 强、唐 烽）
Cover Story：Specimens and restored diagrams of Juramaia sinensis (Eutheria) (left) and Eoandromeda octobrachiata (right). Juramaia sinensis (Eutheria) is the oldest placental mammal ever discovered in the world, which represents a new milestone in early mammal evolution. Eoandromeda octobrachiata belongs to ctenophore of the primordial group. This discovery provides fossil evidence for tracing the origin of early multicellural living things. The research achievement in the field of paleobiological evolution acquired by three research groups directed respectively by Pro-fessor JI Qiang, Lü Jun-chang and TANG Feng, Institute of Geology, CAGS, ranks jointly the sixth among “Top Ten Scientific and Technological Progresses of CAGS in 2011”. For details, see page 715-729 of this issue. (photo by JI Qiang, TANG Feng)
