∙ 10y agoMost dinosaurs died off about 65 million years ago.
Most life on Earth ended 65 million years ago during what is called the Cretaceous-Paleogene extinction event.
There is substantial scientific evidence of an asteroid or comet impact on Earth that caused or was the primary contributor to the extinction. A few scientists still hold other views, including a massive eruption of volcanoes.

Was the extinction of dinosaurs caused by a metoerite crashing to earth?
Most dinosaurs died off about 65 million years ago. Most life on Earth ended 65 million years ago during what is called the Cretaceous-Paleogene extinction event. There is substantial scientific evidence of an asteroid or comet impact on Earth that caused or was the primary contributor to the extinction. A few scientists still hold other views, including a massive eruption of volcanoes. See related links.
Has earth ever had a meteor strike?
Yes Halley's comet struck Arizona over 63 million years ago and is believed to have caused the extinction of dinosaurs.
The mass extinction at the end of the Mesozoic Era was caused by .?
a comet impacting the earth
What is the name of the comet that wiped out dinosaurs?
Scientists usually refer to this as an asteroid, not a comet. It's the asteroid that caused the Chicxulub crater.
Has a Comet Ever Hit?
It is very likely that a comet has hit the earth in the distant past. It is possible that a comet striking the earth led to the extinction of the dinosaur.

Scientists usually refer to this as an asteroid, not a comet. It's the asteroid that caused the Chicxulub crater.
Why was the comet impact a chance happening that benefited the evolution of humans?
Because that comet, which sent many dinosaurs into extinction, caused the mammals to go through a large adaptive radiation event that allowed the vast variation in mammals we see today, especially the variations called apes.
When was the last time a comet hit earth and caused an extinction?
The Cretaceous Paleogene extinction event about 65 million years ago.
Has a Comet Ever Hit?
It is very likely that a comet has hit the earth in the distant past. It is possible that a comet striking the earth led to the extinction of the dinosaur.
How might a collision with a meteor or comet have caused the extinction of the dinosaurs?
The asteroid impact would have thrown an enormous amount of dust and ash into the atmosphere. This would have blocked out sunlight for months or years, killing plants. With no plants to eat, the herbivorous dinosaurs would have starved. The carnivorous dinosaurs would have then starved, since they would have had no prey.
Did Luis Walter Alvarez have a brother?
Yes, Luis Walter Alvarez had a brother named Walter Alvarez who was also a renowned scientist. Walter Alvarez is best known for his work on the hypothesis that a comet impact caused the mass extinction of dinosaurs.
Why is it important to understand the cause of the dinosaurs extinction?
Understanding the causes of an extinction can help us prepare for and hopefully prevent a similar situation in the future. The fact that as much as 90% of dinosaur species died out from climate change near the end of the Mesozoic warns us not to allow global warming to get out of hand. Because we know that the death blow to the dinosaurs was the asteroid impact, astronomers keep track of Near Earth Objects, and are formulating plans for deflecting a large asteroid or comet in the event that one heads toward Earth.
Why don't dinosaurs existed?
They did exist, between around 225-65 million years ago, and were wiped out by the last Mass Extinction Event (summised to be a comet impact).
What dinosaurs survived that comet?
There are numerous theories on why Dinosaurs became extinct. One that is widely accepted is that a comet caused a massive disruption of the earths climate and Dinosaurs could not adapt quickly enough and therefor died out.See the National Geographic reference for a thorough discussion of this topic.
