What plants existed during the Triassic period?
During the Triassic Period (245–200 million years ago), the earliest dinosaurs evolved from reptiles and began to colonize the land, air, and water. Huge seed ferns and conifers dominated the forests, and modern corals, fish, and insects evolved. The supercontinent Pangaea started to separate into Laurasia (today’s Northern Hemisphere continents) and Gondwanaland (today’s Southern Hemisphere continents). The Triassic Period ended with a mass extinction.
