Antwort How old are dinosaurs? Weitere Antworten – Did dinosaurs exist at the same time as humans

No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth.Triassic Period
Approximately 230 million years ago, during the Triassic Period, the dinosaurs appeared, evolved from the reptiles. Plateosaurus was one of the first large plant-eating dinosaurs, a relative of the much larger sauropods. It grew to about 9 meters in length.252 to 66 million years ago
Dinosaurs lived during the Mesozoic Era (252 to 66 million years ago), often called the “Age of Dinosaurs.” The Mesozoic Era is divided into three time periods, the Triassic, Jurassic, and Cretaceous.

How long did dinosaurs live on Earth : about 165 million years
Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.

Could dinosaurs survive today

Many of them probably could survive today. Dinosaurs ruled the world for 150 million years, and endured hot and cold spells, volcanic eruptions, and changing sea levels. There is nothing about today's world that would be fatal to them.

Would humans exist if dinosaurs didn’t go extinct : “If we speculate that humans had evolved alongside dinosaurs, then they probably would have been able to co-exist,” says Farke. “Humans already evolved in ecosystems that had large land animals and predators. We probably would have done okay.”

There are later descriptions of creatures in the Bible that could be referring to dinosaurs. One example is the behemoth of Job 40:15-19. Even in fairly modern history there are reports of creatures which seem to fit the description of dinosaurs.

Paleontologists don't know for certain, but perhaps a large body size protected them from most predators, helped to regulate internal body temperature, or let them reach new sources of food (some probably browsed treetops, as giraffes do today).

When did T-Rex live

83.6 million years ago – 66 million years ago (Cretaceous)Tyrannosaurus / LivedThere are later descriptions of creatures in the Bible that could be referring to dinosaurs. One example is the behemoth of Job 40:15-19. Even in fairly modern history there are reports of creatures which seem to fit the description of dinosaurs.It is therefore entirely possible for prehistoric genetic material to survive for up to one million years. But the big dinosaurs departed this life some 66 million years ago. So the prospect of finding enough viable DNA material in what remains of them today is therefore vanishingly remote.

There were no Polar Ice Sheets. Instead Antarctica was covered in forests where T-Rex. And other dinosaurs could have roamed flowering plants were thriving.

Could dinosaurs exist again : But, based on everything we know at this moment in time, the answer is a firm “No”. It is possible that we may discover something tomorrow, or next year, or sometime in the future, that would let us reconstruct the DNA of extinct dinosaurs and to clone them and bring them back to life…

Could dinosaurs evolve again : But could the more canonical dinosaurs, like Tyrannosaurus, Triceratops and Stegosaurus, evolve again, if the climate and temperature switched back to what the conditions were like during the Cretaceous Probably not. While it's a fun thought experiment, we really can't predict what will evolve in the future.

How do we know dinosaurs existed

How do we know about them, then All of our direct evidence of dinosaurs comes from the geologic record: from Triassic, Jurassic, and Cretaceous sedimentary rock formations around the world. Sedimentary rocks are those that are made up of materials deposited at the Earth's surface, e.g., sediments.

The end of dinosaurs' rule: the Cretaceous extinction. After more than 140 million years in charge, the reign of the dinosaurs came to an abrupt end when a huge asteroid strike and massive volcanic eruptions caused disastrous changes to the environment. Most dinosaurs went extinct. Only birds remained.89.8 million years ago – 72.1 million years ago (Cretaceous – Maastrichtian)Velociraptor / Lived

What is older than T. rex : A new study published Thursday (Jan 11) in the journal 'Scientific Reports' revealed that the skull dates to between 73 million and 71 million years ago. It means that T. mcraeensis was 3 to 5 million years older than T. rex.
