Many scientists believe that something other than asteroids have caused most catastrophic extinctions because some events, like the Permian extinction, show multiple stressors occurred simultaneously. The Deccan Traps volcanic eruptions coincide with the extinction of dinosaurs, suggesting a connection. Additionally, gradual environmental changes and feedback loops could have contributed to mass extinctions more than singular events like asteroid impacts.
It was larger than some other dinosaurs and had a unique shape.
Many paleontologists now classify birds as dinosaurs, but other than that, no.
Yes, sharks have existed longer than dinosaurs. Sharks first appeared over 400 million years ago, well before dinosaurs emerged around 230 million years ago. While dinosaurs dominated the Earth for about 165 million years, many shark species have survived through multiple mass extinctions, continuing to thrive in modern oceans. Thus, sharks have a much longer evolutionary history than dinosaurs.
A dinosaurs weight would depend on the type and size of it. some dinosaurs weigh less than others.
Yes. Scientists have now determined that birds are dinosaurs. Other than that, no.
This would be an incorrect premise, the most obvious answer being that Dinosaurs ruled the earth long before humans came along. Dinosaurs are now extinct and that would have been more than a mass extinction, it was global extinction.
Dinosaurs as most people think of them are completely extinct. However, birds evolved from dinosaurs, and as such, are considered to be a group of dinosaurs. Since birds are still alive today, so are some dinosaurs. No dinosaurs other than birds are alive today, though.
No modern bird is more closely related to dinosaurs than any other.
Some people believe that dinosaurs evolved from other reptiles more than 230 million years ago. Other people believe that God put them here.
Technically there are dinosaurs still around. Most paleontologists now classify birds as dinosaurs. Other than that, the dinosaurs are believed to have been wiped out by an asteroid or comet impact 65.5 million years ago.
