The asteroid that ended the dinosaur age struck Mexico's Yucatán Peninsula about 66 million years ago, and the sulphur-rich rocks beneath it helped turn a roughly 10-kilometre object into a global climate disaster
New scientific findings clarify how an asteroid impact 66 million years ago triggered a global climate catastrophe and reshaped biological evolution.

Where it stands
The mass extinction of dinosaurs was driven by immediate, lethal heat waves and a subsequent, prolonged climate collapse. Following the impact of a roughly 10-kilometre object in the Yucatán Peninsula, dust trapped in the atmosphere is believed to have incinerated life within hours. The vaporisation of sulphur-rich rocks further altered the global environment, creating the conditions that defined the post-impact era.
Coverage from Space Daily and Science News details the mechanics of the collision, specifically how the composition of the subterranean rock amplified the asteroid's destructive potential. Meanwhile, the Jefferson City News Tribune and Live Science examine the aftermath, exploring theories regarding how fungi may have gained an evolutionary advantage and how these conditions ultimately facilitated the rise of mammals. The scientific community is now re-evaluating the sequence of these extinction events.
Researchers are focusing on the 'second strike' effect to determine how specific environmental shifts immediately following the impact transitioned into long-term ecological changes. While evidence supports the role of atmospheric dust and heat, the precise timeline of biological recovery remains a subject of investigation.

Answered
Where did the asteroid strike?
The impact occurred on the Yucatán Peninsula approximately 66 million years ago.
How large was the asteroid?
The asteroid was approximately 10 kilometres in size.
What factors contributed to the climate disaster?
The impact caused heat-trapping dust to enter the atmosphere and vaporised sulphur-rich rocks, leading to rapid heating and long-term environmental instability.
