Dinosaurs might have ultimately been doomed by death from below in the form of monumental volcanic eruptions.

The suggestion is based on new research that is part of a growing body of evidence indicating a space rock alone did not wipe out the giant reptiles.

The Age of Dinosaurs ended roughly 65 million years ago with the K-T or Cretaceous-Tertiary extinction event, which killed off all dinosaurs save those that became birds, as well as roughly half of all species on the planet, including pterosaurs. The prime suspect in this ancient murder mystery is an asteroid or comet impact, which left a vast crater at Chicxulub on the coast of Mexico.

Another leading culprit is a series of colossal volcanic eruptions that occurred between 63 million to 67 million years ago. These created the gigantic Deccan Traps lava beds in India, whose original extent may have covered as much as 580,000 square miles (1.5 million square kilometers), or more than twice the area of Texas.

Probably the most popular theory right now is the Asteroid Theory. According to this theory a large asteroid or comet collided with Earth about 65 million years ago. Scientists think that such a large collision would throw so much dust into the air that sunlight would not be able to shine and plants and animals would die. The dramatic changes in climate that resulted from this huge collision were too much for the dinosaurs. They were not able to survive.
Another theory that could explain how the dinosaurs became extinct is volcanic activity. A huge increase in volcanic activity at around 65 millions years ago could have pumped so much ash into the air that it blocked out the sun killing the dinosaurs.

Many theories are there but most popular one is sudden rise in temeprature in climate and asteoroid hiting the earth made them extinct.
