It is believed that a meteor striking earth brought about the extinction of the dinosaurs. A huge cloud of dust was cast high into the sky, blocking out the sunlight, and reducing the temperature.

Separate trails of evidence demonstrate massive world-wide deposits of volcanic ash around the same time. It's not as if we have news footage of the events, but we are always accumulating and analyzing data as it is uncovered.

How do scientists believe that a great flood killed the dinosaurs?
Scientists do not believe that the extinction of the dinosaurs was the result of a great flood. There are still a number of competing theories about the extinction of the dinosaurs although it is clear that there was a large meteor impact in the Yucatan region, which played a role. It may also be that rising carbon dioxide levels and ocean acidity played a role as well. It may be that there were a number of contributing factors, rather than just one single cause. But scientists do not think that flooding was involved. Note that some dinosaurs were aquatic, and would not have been killed by flooding since they already lived in the water.
Most scientists now believe that birds evolved directly from bipedal?
Most scientists believe that birds evolved directly from bipedal, terrestrial dinosaurs.
Why do scientists believe that birds evolved from dinosaurs?
Birds are thought to have evolved from bipedal dinosaurs.
Scientists have found a huge underwater crater in Mexico that they believe could be linked to the extinction of the dinosaurs What event 65 million years ago most likely caused this crater?
The event that was marked by an asteroid hitting the Earth 65.5 million years ago near modern day Chixulub in the Yucatan Peninsula in Mexico is known as the K-T or Cretaceous-Tertiary Extinction Event.
What was the mass extinction in the mesozoic era caused by?
You are probably asking about the mass extinction at the Cretaceous-Mesozoic boundary, about 65 million years ago. We know that there was a major meteoric impact in the Yucatan peninsula at that time, which was at least partially involved in the mass extinction; some scientists believe that there were other contributing factors, but it remains a complicated and difficult issue to investigate.
Does an asteroid contribute to extinction?
I believe it does. Scientists think that an asteroid wiped out the dinosaurs.
How do scientists tie biblical creation in with the extinction of the dinosaurs?
Most scientists do not believe in Biblical Creation, so there is no reason to tie it with the extinction of dinosaurs. However, Creationists often say that humans originally co-existed alongside dinosaurs until the Great Flood, when dinosaurs all drowned.
What do scientists believe dinosaurs evolved from?
Birds, which are not just considered descendants of dinosaurs; they are dinosaurs.
How do scientists believe that a great flood killed the dinosaurs?

How many years were dinsoaurs on earth?
Scientists believe dinosaurs roamed the earth for roughly 180 million years, longer than any other creature on earth. The few dinosaurs that survived the mass extinction lived into the Jurassic period.
Most scientists now believe that birds evolved directly from bipedal?
Most scientists believe that birds evolved directly from bipedal, terrestrial dinosaurs.
Is the extincion of dinos are real?
The scientists believe that dinosaurs were extinct.
Why did archelon turtles become extinct?
The Archelon became extinct at the end of the Triassic period, at the same time as the dinosaurs. Because of this, scientists believe the k-2 extinction is to blame. The k-2 extinction is the giant meteor that impacted Earth.
Are dinosaurs monsters?
dinosaurs are monsters from the past. scientists believe dinosaurs lived 3.5 billion to 200 million years ogo
Are chickens dinosaurs?
Chickens are birds, which scientists believe descended from the dinosaurs. So, in a way, yes, chickens are dinosaurs.
What animal did scientists believe were most similar to dinosaurs?
The birds, having evolved from dinosaurs, are their closest living relatives. Crocodilians are the second closest relative of dinosaurs.
Did dinosaurs live Cenozoic era?
The general answer would be no, dinosaurs lived in the Mesozoic. However, many scientists believe that modern birds, which have lived throughout the Cenozoic, are dinosaurs.
