Did the impact of a large meteorite cause the extinction of the dinosaurs?

Well, it was an awful long time between the extinction of the dinosaours (about 65 million years ago) until "we" showed up - about 50 thousand years ago. So I think you'd be safe to say their extinction didn't have any effect on us, per se.. However, whatever caused their extinction did lead to the emergence of other types of animals on the planet, mammals being one of them, who may not have prospered so well had they all been eaten by dinosaurs. Despite what some people might think, 'mankind' and 'dinosaurs' never walked the earth together. Except for crocodiles, and perhaps, sharks - they've been around A Long Time, and may be the only surviving link to the age of Reptiles.

What are examples of mass extinctions?
The K-T (Cretaceous and Tertiary) boundary event thought to have been caused by the impact of a large meteorite forming the Chicxulub crater as well as very large scale volcanic activity (in this case the large igneous province known as the Deccan Traps) is a very good example and is thought to have been responsible for the extinction of the dinosaurs.
Did the cretaceous or permian extinction cause dinosaurs to become extinct?
No, as there was no Cretaceous-Permian extinction. There was the Permian-Triassic extinction, which ocurred before the dinosaurs appeared. Non-avian dinosaurs were wiped out in the Cretaceous-Paleogene extinction.
Did asteroids cause the mass extinction of dinosaurs?
I think so.
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
Can anything other than an earthquake cause a tsunami?
nothing else except maybe a large enough meteorite impact. The one that killed the dinosaurs I'll bet had a nice sized tsunami.
What does a 65.5 million year old impact crater in Mexico provide evidence for?
At the very least, that it was caused by a meteorite falling to Earth. According to calculations, the "rock" had 4.1 to 4.4 kilometers (2.5-2.7 miles) of diameter. It is also theorized that such impact was the cause of the KT Extinction Event, commonly known as the "dinosaur extinction".
What is one type of catastrophic change that can cause a mass extinction?
One type of catastrophic change that can cause a mass extinction is an asteroid impact. When a large asteroid collides with the Earth, it can release massive amounts of energy, cause widespread destruction, trigger tsunamis and wildfires, and create a global "impact winter" due to the release of dust and debris into the atmosphere. Such an event is believed to have caused the extinction of the dinosaurs 65 million years ago.
When did the Cretaceous Tertiary extinction occur?
About 65.5 million years ago. The Cretaceous and Tertiary are geological time periods either side of this event. The event is significant because there was a large mass extinction event at this time including the extinction of all non avian dinosaurs. Most experts agree that the cause of the extinction was a asteroid impact.
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 humans cause the extinction of dinosaurs?
No. Humans and dinosaurs never met. Dinosaurs died out 65 million years ago. The human race is about 200,000 years old.
When did dinosaurs?
Non-avian dinosaurs existed from around 230 million years ago in the Triassic period until the end of the Cretaceous period, 65 million years ago. The cause of their extinction is most likely an asteroid impact coupled with environmental change.
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.
