A current theory that is widely accepted and supported by a great deal of evidence is that organisms were significantly affected by the environmental effects of the Chicxulub meteor impact, leading to the disruption of the food chain and the extinction of nearly 60% of the existing species that existed at that time including the non avian dinosaurs.
Essentially, the atmospheric dust and gas created prevented the Earth's plants from receiving enough sunlight over a period of many years. The colder climate also reduced the habitats of cold-blooded reptiles like the dinosaurs.
Another event that is thought to have contributed to this mass extinction is the occurrence of very large scale volcanic eruptions (known as a large igneous province) in this case known as the Deccan Traps that produced significant volumes of volcanic gasses that contributed to global cooling.
Dinosaurs were a casualty of one, or a combination of, these events.
it is a metor rock that crushes into the earth kill the dinosaurs
It is not a "who" but a what that killed off the dinosaurs. It is thought that an asteroid hit the earth causing a prolonged winter which killed off all the plants so they starved to death and died.
No, it wasn't lava that killed the dinosaurs. The most widely accepted theory is that they were killed by an asteroid impact that caused a chain reaction of events, including massive wildfires, climate change, and the destruction of food sources. This event led to the extinction of most species on Earth, including the dinosaurs.
No, not a meteor shower. The dinosaurs became extinct after a meteor struck the earth which blocked out the sun and killed much of the vegetataion that the dinosaurs used for food.
The dinosaurs were killed by an asteroid impact around 66 million years ago at the end of the Cretaceous period. This event triggered mass extinctions and led to the decline of dinosaurs and the rise of mammals as the dominant terrestrial animals.
The theory is that it was a large meteorite striking the earth that caused a huge dust cloud to rise and blot out the sun. As plant life succumbed to lack of light, so plant eaters died off first. With no plant eaters to prey on, the carnivore dinosaurs also died eventually from lack of food.
No, the majority of the scientific community has come to the conclusion that the dinosaurs were killed off by a meteor impact 65 million years ago.
Homosapiens (humans) did not exist until after the dinosaurs were already gone.
what is your conclusion about what killed the dinosaurs
No one knows what killed the dinosaurs.
It is not a "who" but a what that killed off the dinosaurs. It is thought that an asteroid hit the earth causing a prolonged winter which killed off all the plants so they starved to death and died.
it's what killed the dinosaurs.
some predict the the dinosaurs died of a big asteroid.
that's what killed the dinosaurs
The dinosaurs were killed by a very, very large rock called a woodwind.
Actually volcanos and meteorites killed the dinosaurs the crater hit Mexico and volcanos all over the world were the dinosaurs lived
Nobody knows for sure but they think dinosaurs were killed by a giant astroid.
because not all the dinosaurs were killed some survived
