After 30 years of intense controversy and often unscholarly invective, KT studies may have finally reached the point where the sum of scientific evidence points overwhelmingly away from a KT impact and towards volcanism and associated climate and environmental changes as the likely cause for the mass extinction. .

Why Did the Dinosaurs Die Out?

Other factors such as extensive release of volcanic gases, climatic cooling (with related changes in ocean currents and weather patterns), sea-level change, low reproduction rates, poison gases from a comet, or changes in the Earth's orbit or magnetic field may have contributed to this extinction event.

New Blow for Dinosaur-Killing Asteroid Theory

Keller suggests that the massive volcanic eruptions at the Deccan Traps in India may be responsible for the extinction, releasing huge amounts of dust and gases that could have blocked out sunlight and brought about a significant greenhouse effect.

More Than a Meteor Likely Killed Dinosaurs 65 Million Years Ago

The story that seems to be taking shape, according to Keller, is that Chicxulub, though violent, actually conspired with the prolonged and gigantic volcanic eruptions of the Deccan Flood Basalts in India, as well as with climate change, to nudge species towards the brink.

More Than a Meteor Likely Killed Dinosaurs 65 Million Years Ago

Growing evidence shows that the dinosaurs and their contemporaries were not wiped out by the famed Chicxulub meteor impact alone, according to a paleontologist who says multiple meteor impacts, massive volcanism in India and climate changes culminated in the end of the Cretaceous Period.
