Comet explosion 13,000 yrs ago led to mammoths' extinction: Study
A massive cosmic explosion may have led to the extinction of mammoths, a research stated. A fragmented comet exploded in the atmosphere nearly 13,000 years ago, triggering intense heat and widespread burning causing the smoke to block the sun, leading to an 'impact winter'. Hence, the shockwaves, followed by harsh conditions, led to the collapse of Ice Age megafauna.
