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.
The Jurassic period lasted from about 201 to 145 million years ago. During this time, many different species of dinosaurs existed. The end of the Jurassic period marked the extinction of some of these dinosaur species, while others survived and evolved into the next period.
Non-avian dinosaurs went extinct 65.5 years ago. However, most paleontologists not classify birds as dinosaurs. So, in a sense they never truly died out.
The Jurassic (named for the Jura Mountains) Period gave way to the Cretaceous about 145 million years ago.

Are turkeys dinosaurs?
No. Turtle are from a branch of reptiles completely separate from dinosaurs.
Did the dinosaurs extinct at once?
No, dinosaurs did not go extinct all at once. The extinction event that wiped out the non-avian dinosaurs around 66 million years ago is believed to have happened relatively quickly in geologic terms, but not instantaneously. Some species may have gone extinct earlier or later than others due to various factors.
Who studies dinosaurs?
Paleontologists study dinosaurs. They analyze fossils and use their findings to understand how dinosaurs lived, evolved, and interacted with their environment.
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.
When was Dinosaurs Don't Die created?
Dinosaurs Don't Die was created in 1975.

No
Why did dinosaurs die of hunger?
It isn't proven that the dinosaurs died from hunger. See the related question below.
Did all the dinosaurs die out?
AnswerYes, all the true dinosaurs died out approximately 64 million years ago. The nearest living relatives of dinosaurs are the birds.
Why did dinosaurs have to die?
