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.
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.
Approximately when did the mass extinction of dinosaurs occur?
The mass extinction of dinosaurs occurred around 66 million years ago during the Cretaceous-Paleogene (K-Pg) boundary.
Did the breakup of Pangaea have a effect on dinosaur extinction?
No, the breakup of Pangaea occurred long before the mass extinction of dinosaurs. The main factor believed to have caused dinosaur extinction is an asteroid impact that occurred around 66 million years ago.
Was the extinction of dinosaurs caused by a comet crashing to earth?
no a dieses killed all the dinosaurs but we may never know if i am wrong or right No, The reason for their ending may be because of the Flood that happened in the Bible, If you look it up in Genesis you can read more.
When was the first mass extinction?
540 million years ago was the first mass extinction
When was the last time a comet hit earth and caused an extinction?
The Cretaceous Paleogene extinction event about 65 million years ago.
Did the Permian extinction come before the the dinosaur extinction?
Yes. At the time of ther Permian extinction 251 million years ago dinosaurs had not yet evolved. The dinosaur extinction was 65 million years ago.
When did the three mass extiintion happen?
The three mass extinctions referred to are the Permian-Triassic extinction about 252 million years ago, the Triassic-Jurassic extinction about 201 million years ago, and the Cretaceous-Paleogene extinction about 66 million years ago.
What happened 65 million years ago?
About 65 million years ago was the Cretaceous-Paleongene excintion event, likely caused by a combination of an asteroid impact and a surge in volcanic activity. A number of groups of animals went extinct including ammonites, pterosaurs, plesiosaurs, and dinosaurs.

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.

What caused the Devonian Extinction?
Evidence leads most paleontologists to believe the Devonian mass extinction event to be caused by global cooling, triggered by a glaciation event on Godwana. A less-proven theory states the extinction could have also been caused by meteoric impact.Background Info:After the Ordovician mass extinction event around 440 - 450 million years ago, surviving groups of species continued to diversify evolutionarily into what became the Silurian and Devonian periods.The Devonian period spanned from 408-360 million years ago, in which came the first sharks, bony fish, and ammonoids (a type of predatory mollusk) in the ocean, as well as terrestrial amphibians, insects, and true land plants.
