125 Million Years Ago, One of the World's Very First Flowers Bloomed

Ferocious dinosaurs roamed the Earth during the early Cretaceous Period (145 to 100 million years ago), but beneath their giant feet, a tiny—yet important—evolutionary movement was beginning to take root. During the previous Jurassic Era, the world had been filled with ferns, conifers, and cycads, and nary a flower bloomed. This changed around 125 million years ago, our fossil records show, when one of the word’s very first flowers, Archaefructus liaoningensis, sprouted in what is now northeastern China. This preserved plant marks the beginning of angiosperms, which are fruiting plants that rely on animals to spread their capsule-enclosed seeds.

In the video below, PBS Eons explains why angiosperms were so important to early life on Earth, and how they took over the world to eventually account for more than 80 percent of the world’s terrestrial plants.
