When did the age of dinosaurs end?

The age of the dinosaurs came to an end approximately 65 million years ago. From this point in time, there are currently no known dinosaur fossils. The time of the great dinosaur (and other species) extinction is used by scientists to delineate the end of the Cretaceous period as well as the end of the Mesozoic era. After this point, the Cenozoic era begins, starting with the Tertiary period.
