中文摘要：

Conchostracans 和 corixids 是现存蝾螈的食谱的部分，在湖的环境的一个生态地重要的事实。这里，我们在水的侏罗记蝾螈 Jeholotriton paradoxus 和 Chunerpeton tianyiensis 的勇气报导他们的发现，在 Daohugou 先前丰富， Ningcheng 县，内部蒙古，中国。这揭示这的生态学的一些东西重要，古老，脊椎动物和无脊椎的集合。新石块证据显示这些侏罗记蝾螈的高度选择的喂；仅仅 conchostracan Euestheria luanpingensis 的少年上的 Jeholotriton preyed，和仅仅 corixid Yanliaocorixa chinensis 上的 Chunerpeton。我们能作为不同的颚和 U 字形的结构的后果推断饮食的差别；并且这样壁龛在侏罗记蝾螈划分。

英文摘要：

Conchostracans and corixids are part of the diet of extant salamanders, an ecologically important fact in a lacustrine environment. Here we report their discovery in the guts of the aquatic Jurassic salamanders Jeholotriton paradoxus and Chunerpeton tianyiensis, formerly abundant at Daohugou, Ningcheng County, Inner Mongolia, China. This reveals something of the ecology of this important, ancient, vertebrate and invertebrate assemblage. The new fossil evidence indicates the highly selective feeding of these Jurassic salamanders; Jeholotriton preyed only on juveniles of the conchostracan Euestheria luanpingensis, and Chunerpeton only on the corixid Yanliaocorixa chinensis. We can infer the dietary differences as a consequence of different jaw and hyoid structures; and thus niche partitioning in Jurassic salamanders.
