245 million years ago to 65 million years ago, so about 180 million years. If you mean individually, I think it differs between the different species
.
if you are a Christian and you believe The Bible, it says that dinosaurs lived with man, which is about 6000 years ago.
They died about 65,000,000,000 years ago. If you can't read the number here it is in words: Sixty-five million years ago
From 251-65 million years ago
No dinosaurs are not still alive there are some relatives of dinosaurs that have been alive since dinosaurs like alligators and crocodiles even tigers and elephants.
There have been no dinosaurs alive for millions of years, let alone last century.
Crocodile it has been alive since the dinosaurs
alligators get as old as 73 to 75 years old as the average human does. They have been around even longer than dinosaurs have been alive. Most dinosaurs have evolved from crocidiels such as a "Leoplurodon"
No and yes. Dinosaurs have long been extinct long long long before humans came about. However we live in close proximity to their descendants. Birds namely, so keep that in mind next time you see a robin or pigeon outside that it was descended from long extinct dinosaurs.
In the sense that birds are dinosaurs, and thus that dinosaurs are still alive, yes. However they were not alive when non-avian dinosaurs were around. Parrots did not evolve until a few million years after non-avian dinosaurs died out.
Dinosaurs have long been extinct, making it impossible for scientists to work with living dinosaurs.
i think the sky was always blue...
That is a matter of opinion. To me, it would be the crocodile as it has been alive since the age of the dinosaurs.
None. Dinosaurs had been extinct for approximately 65 million years before the start of the Revolutionary War.
yes, cavemen were alive.
no there are not
