The Baishan Basin, situated in southeastern Jilin is one of the easternmost Jehol Biota localities in China. Until now, the fossils here belonging to Jehol Biota have not yet been reported except for few fossils listed in geological survey reports. The fossil collections here are noteworthy in that they are the first fossil record documented from the Early Cretaceous Yingzuilazi Formation of the Baishan Basin, southeastern Jilin and the easternmost locality of Jehol Biota, China. This finding is important to explore the distribution, evolution and biodiversity of the Jehol Biota and even the Late Mesozoic terrestrial ecosystem, as well as for the division and correlation of the Late Mesozoic terrestrial strata.展开更多
