It has a relatively wide range of Jurassic-Cretaceous-Tertiary stratum in Southwest China, and the Lufeng County is also the Lufengosaurus living Area in Yunnan Province. The meteorite impact is an important reason for the widespread acceptance of the Cretaceous / Tertiary biological extinction, and even the main reason. I want to apply for a topic in this area to compare with the evidence in other parts of the world. My next article is about the meteorite impact of the Cretaceous/Tertiary boundary recently. Welcome everyone to give me suggestions ! Interested parties can cooperate.
