The group originated and diversified during the Early Cretaceous and became ecologically significant thereafter. [110] Flower-like structures first appear in the fossil records some ~130 mya, in the Cretaceous. [111]
The fossil history of flowering plants records the development of flowers and other distinctive structures of the angiosperms, now the dominant group of plants on land.The history is controversial as flowering plants appear in great diversity in the Cretaceous, with scanty and debatable records before that, creating a puzzle for evolutionary biologists that Charles Darwin named an "abominable ...

The origin time of the crown group of flowering plants remains contentious. [52] By the Late Cretaceous, angiosperms appear to have dominated environments formerly occupied by ferns and gymnosperms. Large canopy -forming trees replaced conifers as the dominant trees close to the end of the Cretaceous, 66 million years ago. [ 53 ]
