摘　　要：The Early Cretaceous Jehol Biota,renowned for its exceptionally wellpreserved volcanic-influenced ecosystem, was buried in lacustrine and occasionally fluvial sediments. This includes, notably, the Huajiying, Yixian and Jiufotang Formations in northern Hebei and western Liaoning and equivalent ash-interbedding sediments in neighboring areas [1–3](Fig. 1). It harbors many evolutionarily significant taxonomies, e.g. feathered dinosaurs,early birds, mammals and flowering plants, representing one of the most diversified terrestrial biotas of the Mesozoic [1,2,4].
