What first appeared in the Cretaceous period?

First Flowering Plants

Angiosperms (flowering plants) appeared in the fossil record more than 100 million years ago during the Cretaceous Period. Once they appeared, they quickly became the dominant type of plant life on land and remain so today. The earliest angiosperms evolved from a specialized group of seed ferns.Jan 4, 2021

What was before the dinosaur age?

The age immediately prior to the dinosaurs was called the Permian. Although there were amphibious reptiles, early versions of the dinosaurs, the dominant life form was the trilobite, visually somewhere between a wood louse and an armadillo. In their heyday there were 15,000 kinds of trilobite.Feb 22, 2001
