摘　　要：The Cretaceous,lasting from 145 to 66 million years ago,was a time period of major turnover in terrestrial and marine ecosystems when many modern groups of plants and animals appeared for the first time.The Cretaceous was also famously terminated abruptly by the impact of a huge asteroid that wiped out such classic animals as dinosaurs and pterosaurs,but these organisms were supposedly killed in their prime,with no pre-extinction diversity decline[1].A new study[2]identifies a long-term decline in the pterosaurs,lasting some 60 million years of the middle and late Cretaceous,before their final disappearance.
