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.
What else can I help you with?
Are turkeys dinosaurs?
No. Turtle are from a branch of reptiles completely separate from dinosaurs.
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.
Who studies dinosaurs?
A paleontologist (pay-lee-un-TAH-lah-jist) studies the fossils of dinosaurs.
Were all dinosuars carnivores?
No, not all dinosaurs were carnivores. There were herbivorous dinosaurs that primarily ate plants, such as the Triceratops and the Apatosaurus. Additionally, some dinosaurs were omnivores, meaning they ate both plants and meat.
Did dinosaurs have mitochondrian?
Considering that most eukaryotic cells have mitochondria and that dinosaurs are eukaryotes like all other animals that ever lived, it is certain that they did have mitochondria in their cells. In fact, birds are considered dinosaurs (they certainly descended from dinosaurs) and their cells have mitochondria, so we can be as sure as scientifically possible that dinosaurs indeed did have mitochondria.
How would the dropping temperatures impact the dinosaurs?
if temperature drops quick enough, plants die. if plants die, the dinosaurs that eat plants die. if those dinosaurs die, then the carnivorous meat-eating dinosaurs die. then, all dinosaurs die.
Did dinosaurs completely die out?
Birds are direct descendants of dinosaurs so they did not die out.

Dinosaurs Don't Die was created in 1975.
