Dinosaurs were thought to have shown a substantial diversification in their last 50 million years, from the mid-Cretaceous onwards, when new groups such as the duckbilled hadrosaurs, the horned ceratopsians, and many new predators appeared.
This mid-Cretaceous expansion seemed to coincide with the Cretaceous Terrestrial Revolution, the time when modern ecosystems became established on land, with flowering plants, social insects, lizards, snakes, birds and mammals.
A thorough numerical study now shows that this picture is incorrect: dinosaurs had done all their diversifying much earlier in their history, and they did not participate in the Cretaceous explosion of life on land.
