When the dinosaurs existed, the world was much warmer than it is today. There were many warm, shallow seas.
The primary plants included conifers, tree ferns, cycads, and, during the Jurassic, ginkgos. In the early Cretaceous, the last period when non avian dinosaurs lived, the first flowering plants appeared, and, before the extinction of the dinosaurs, early grasses grew near riverbeds, and there were palms and Magnolids.
Besides dinosaurs, there were pterosaurs in the sky, and icthyosaurs, plesiosaurs, mosasars, and thalattosuchians lived in the oceans. Many modern animal groups, such as mammals, birds, crocodillians, turtles, frogs, and salamanders evolved during the time that non avian dinosaurs existed.
