The largest extinction of animals commonly called dinosaurs was around 65 million years ago, in a time period known as the Cretaceous-Tertiary extinction event, which lasted somewhere from several to several thousand years (evidence is not determinate on the exact length of the event for several reasons, and above-mean rates of extinction persisted for quite some time). This view is supported by the vast majority of scientific evidence and knowledge.Some dinosaurs did survive however, to become extinct at much later times, and others had gone extinct much earlier, so one could technically describe all of the last 230 million years as "when [the] dinosaurs became extinct".There is a substantial number of scientists, however, who would say that, technically speaking, "the dinosaurs" did not become extinct at all, because one group is still with us: the birds. There is considerable evidence that birds are descended from a group of dinosaurs known as Maniraptora (see the related link below), which would indicate that birds are properly included within the dinosaur clade (group of organisms related by descent).All the dinosaurs went extinct about 65 million years ago after a giant asteroid hit earth.
