Two Jurassic salamanders with stomach contents from Inner Mongolia, China

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