When you imagine prehistoric life, it’s likely that the first thing that comes to mind are dinosaurs: long-necked Apatosauruses, flying Pterosaurs, big toothy Tyrannosaurs. But what don’t get as much attention are the prehistoric plants that lived alongside them.

Plants, shrubs, and trees played a key part in the food chains of dinosaurs, and many dinosaurs evolved to match the plant life available to them. The Apatosaurus’ long neck, for example, developed to reach leaves high up in prehistoric trees.

Joining Host Flora Lichtman to defend the importance of prehistoric plants is Riley Black, author of the new book When the Earth Was Green: Plants, Animals and Evolution’s Greatest Romance. She’s based in Salt Lake City, Utah.
