For ten million years prior to the K-T Extinction that wiped out the dinosaurs, massive volcanic traps were erupting in India. They released massive amounts of greenhouse gases, which altered the climate. The altered climate had decreased dinosaur biodiversity to one tenth of what it had been by 65.5 million years ago. Some paleontologists believe that this is what wiped out the dinosaurs.
What else can I help you with?
Why did scientist modify their theory about the extinction of the dinosaurs?
because they realised they were wrong.
3 possible contribution of extinction of the dinosaurs between the creatceous and tertiary?
Impact event: The most widely accepted theory is that a large asteroid impact caused drastic environmental changes leading to the extinction of the dinosaurs. Climate change: Volcanic activity and changes in atmospheric composition could have led to significant climate disruption, affecting the food chain and ultimately leading to the extinction of the dinosaurs. Competition and evolution: The rise of new species, particularly mammals, may have outcompeted dinosaurs for resources, leading to their decline and eventual extinction in the Cretaceous-Tertiary boundary.
When did a volcano erupt when dinosaurs live?
One significant volcanic eruption during the time of the dinosaurs was the eruption of the Deccan Traps in India around 66 million years ago. This eruption is thought to have contributed to the mass extinction event that led to the extinction of the dinosaurs.
What survived the extinction event of the dinosaurs-?
Avian dinosaurs survived the extinction event of the dinosaurs.
What is ghost ranches theory for the extinction of coelophysis dinosaurs?
scientist say the die because of a flood and a drought
How did dinosaurs go extinct(theory)?
It is a rock called an asteroid, or comet, or a volcanic eruption.
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.
Walter and luis alvarez think that a large rocky object is what?
Walter and Luis Alvarez proposed the theory that a large rocky object, such as an asteroid or comet, colliding with Earth caused the mass extinction of the dinosaurs. This theory is known as the Alvarez Hypothesis.
Is extinct a noun?
No it is an adjective, extinction is the noun. Dinosaurs are extinct. The extinction of dinosaurs happened a long time ago.
How does the theory of asteroid impact relate to the extinction of Dinosaurs?
I does not. The asteroid would of had to knock out the entire earth for that to happen. If you think of the facts it is just not possible.
Where most likely killed the dinosaurs?
The most widely accepted theory for the mass extinction of dinosaurs is the impact hypothesis, which suggests that a giant asteroid struck the Earth around 66 million years ago, creating the Chicxulub crater in present-day Mexico. This impact would have caused widespread fires, tsunamis, and a "nuclear winter" effect, drastically altering the climate and ecosystems. Additionally, volcanic activity, specifically the Deccan Traps in India, may have contributed by releasing massive amounts of volcanic gases, further destabilizing the environment. Together, these events likely led to the extinction of approximately 75% of Earth's species, including the dinosaurs.
What a sentence for extinction?
It is believed that a meteor strike led to the extinction of dinosaurs
