No, vertebra life has not existed for more than half a billion to a billion years ago. Dinosaurs first appeared about 230 million years ago and died out 65.5 million years ago.
No. Dinosaurs existed 65 billion years ago. The oldest bones of man are 25 million years old. They did not exist at the same time.
Dinosaurs lived between approximately 230 million and 65 million years ago, during the Mesozoic Era, which is divided into the Triassic, Jurassic, and Cretaceous periods. The last dinosaurs disappeared around 65 million years ago, likely due to a mass extinction event. This means that dinosaurs roamed the Earth for about 165 million years before their extinction.
About 248,000,000 years ago Answer:The oldest known Dinosaur is Eoraptor or a Coelophysis, but no one knows exactly what the oldest Dinosaur was, it likely has yet to be discovered. But it's 248 mya (million years ago).I should know i have a dinosaur encyclopedia
4.6 Billion Years
Dinosaurs went extinct.
No. As far as we know, nothing existed 75 billion years ago. The universe is about 13.7 billion years old and Earth about 4.55 billion. Dinosaurs appeared about 230 million years ago and died out 65.5 million years ago. So dinosaurs were around 75 million years ago, not 75 billion.
The universe started 13.8 billion years ago, Earth formed 4.5 billion years ago, and dinosaurs lived from 230 to 65 million years ago. If a billion years was an hour, a minute would be 17 million years, then dinosaurs lived from 13.5 to 3.8 minutes ago. So, from a geological prospective, dinosaurs did not live very long ago.
around 6.5 billion years ago
Dinosaurs lived 65 million years ago.
No. Dinosaurs existed 65 billion years ago. The oldest bones of man are 25 million years old. They did not exist at the same time.
64,000,000 years ago
Dinosaurs died out 65.5 million years ago, and the earliest humans evolved 2.3 million years ago, long after all the dinosaurs had disappeared. Hence, dinosaurs did not live alongside cavemen.
Dinosaurs lived 65 million years ago.
Not that anyone knows of. Though theories have been proven wrong before, all Dinosaur fossils that have been observed have been from 65 million years ago or older.
Not unless you count birds, which most paleontologists consider to be dinosaurs. Non-avian dinosaurs died out 65.5 million years ago.
65 million years ago
230 million years ago
