What is one catastrophic event that can cause a mass extinction?
An asteroid from space, like the one that killed the dinosaurs, which was a mile in width.
How do you use mass extinction in a sentence?
The mass extinction of dinosaurs were caused volcanoes that cause global warming with their toxic gases, therefore, killing the plants, starving the plant eating dinosaurs to death, and with no more plant eating dinosaurs, the meat eating dinosaurs died, too.
Did the dinosaurs extinct at once?
No, not all at once. Throughout the 150 million year "reign" of the dinosaurs, all kinds of groups of dinosaurs have flourished then died out. Dinosaurs living in the Triassic Period were not the same as dinosaurs living in the Cretaceous period. However, the final blow to the dinosaurs that caused them all to die out was the K-T mass extinction that occurred 65 million years ago.
When did the dinosaurs became extingt?
The last dinosaurs became extinct about 65 million years ago at the end of the Cretaceous period.
When did the first dinosaurs appeared on earth?
The first dinosaurs appeared on earth about 250 million years ago just after the Permian-Triassic mass extinction. The Triassic dinosaurs weren't too fierce and they were mainly neutrally defensive, which means they don't attack unless provoked.
Why the huayangosaurus went extinct?
huayangosaurus went extinct in the K/T Mass Extinction in 65 million years ago with all Dinosaurs Went Extinct
What is an example of mass extinction?
When the meteorite hit Earth and killed the dinosaurs.
What is one catastrophic event that can cause a mass extinction?
An asteroid from space, like the one that killed the dinosaurs, which was a mile in width.
Why did life continue to exist after a mass extinction?
Not every animal went extinct, only some, such as the dinosaurs.
Why did the Ornithomimus die out?
Pterodactyls died out along with the dinosaurs and many other animal and plant species during the K-T extinction event. It is believed that an asteroid, along with other environmental changes, struck the Earth and contributed to the mass extinction. Dinosaurs, pterosaurs, and many marine reptiles were not able to cope, so they went extinct.
Did asteroids cause the mass extinction of dinosaurs?
I think so.
Why did trilobites become extinct?
The trilobites went extinct during the mass extinction at the end of the Permian period.
How many years ago was the largest mass extinction?
The most extreme that we are aware of was the Permian Extinction about 252 million years ago, in which 95% of all life was killed. The cause is still unknown, although it is possible that this was an impact event.
When did the mass extinction that killed dinosaurs occur?
In the Late Cretaceous (65 million years ago).
How do you use mass extinction in a sentence?
The mass extinction of dinosaurs were caused volcanoes that cause global warming with their toxic gases, therefore, killing the plants, starving the plant eating dinosaurs to death, and with no more plant eating dinosaurs, the meat eating dinosaurs died, too.
What is likely reason why dinosaurs became extinct?
it is said they died from a total wipe out from a meteor strong enough to kill them all but there are other reasons such as they died from a volcano water loss or maybe a lot of the other died so there was no food for the carnivores
When did dinosaurs and pigs walk the earth?
Dinosaurs: Most got extinct in the mass extinction event, about 65 million years ago. Today's birds and reptiles are generally believed to be the descendants of the dinosaurs.Pigs: They walk on earth today.
