摘要

Mesozoic fossil locality in Linglongta village, Jianchang County, western Liaoning,has drawn extensive attention among paleontologists as producing hundreds of beautifully preserved feathered dinosaurs and mammals. The SIMS U-Pb zircon analyses of zircons derived from three tuff layers in Daxishan section in Linglongta yield (160.7±1.7), (159.5±2.3) and (158.9±1.7) Ma, indicating that they were formed at early Late Jurassic. Such a result is generally consistent with biostratigraphic evidence, providing a maximum known age for the first appearance of feathered dinosaurs.
