Flowering plant first appeared during what time period

Cretaceous period

Explanation: They began changing the way the world looked almost as soon as they appeared on Earth about 130 million years ago, during the Cretaceous period. That's relatively recent in geologic time: If all of Earth's history were compressed into an hour, flowering plants would exist for only the last 90 seconds.

Hope this helps!!
