Yes, all dinosaurs are extinct. They all went extinct millions of years ago. The exact cause of why they all went extinct is debated by scientist and anthropologist.
scientists don't know if an asteroid killed the dinosaurs it is just a guess the dinosaurs died 65 million years ago
The first date has to be an estimate, but since the dinosaurs effectively dominated the mammals by the start of the Jurassic (201 mya) we could reasonably credit them with 136 million years "in charge" using 65 mya (the end of the Cretaceous and a spectacular change in the fossil record) as the second.
Dinosaurs became extinct 65 million years ago, at the end of the Cretaceous period.
None. Dinosaurs had been extinct for approximately 65 million years before the start of the Revolutionary War.
none dinosaurs are extinct
All of them. The last dinosaur died some 65 million years ago.
I think they lived (the dinosaurs) for approximately 165 million years.
No dinosaurs were living on earth one million years ago, as all dinosaurs are thought to have gone extinct 65,000,000 years ago. However some dinosaurs are thought to have evolved into modern birds and other such creatures
