Around the end of the Cretaceous Period.
Dinosaurs became extinct at the end of the Mesozoic Era 65 million years ago. Their extinction also marked the beginning of the Cenozoic Era.
Dinosaurs disappeared near the end of the cretaceous period.
Most people believe it was at the end of the Cretaceous however the truth is that it ended in the Tertiary PERIOD not era so be careful that was why the event was called the K-T event because c had been taken in a mass extinction in the oceans.
All non avian dinosaurs lived in the Mesozoic Era (251 - 65Ma). The mass extinction 65 million years ago of all non avian dinosaurs along with many other types of animals and plants marks the boundary between the Mesozoic and the Cenozoic Eras.

Did dinosaurs become extinct AD or BC?
B.CAnswer:Although the majority of dinosaurs died out about 70 million years ago, the present day birds are evolved from theropods and are direct descendants of the dinosaurs. In that manner dinosaurs have not become extinct.
When did dinosaur's go extinct?
Dinosaurs became extinct 65 million years ago, at the end of the Cretaceous period.
Dinosaurs died in what geological period?
Dinosaurs died in the Cretaceous, Jurassic, and Triassic periods, but became extinct at the end of the Cretaceous.
Did the dinosaurs extinct at once?
No, not all at once. Throughout the 150 million year "reign" of the dinosaurs, all kinds of groups of dinosaurs have flourished then died out. Dinosaurs living in the Triassic Period were not the same as dinosaurs living in the Cretaceous period. However, the final blow to the dinosaurs that caused them all to die out was the K-T mass extinction that occurred 65 million years ago.
When did turrasic dinosaurs die?
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.
