Famous Chicxulub influence This occurred in the Yucatan province of Mexico 66 million years ago by an asteroid 10 to 15 km in size and ended dinosaursmay not have been a major factor in this extinction, at least as determined by a study published in Nature.

The research paper states that the main causes of extinction will be exposure to silicate dust and sulfur produced by the impact, as well as soot from wildfires.

They found that fine dust could remain in the atmosphere for up to 15 years and help cool the Earth’s surface by up to 15°C. They suggest that this dust may have blocked photosynthesis for more than 600 days after the impact, causing a mass extinction of animal and plant species not adapted to survive in conditions of darkness, cold and lack of food.

Jem Burke Senel and his colleagues carried out paleoclimate modeling based on the analysis of fine-grained material embedded in well-preserved impact deposits in North Dakota, USA. They found that the size distribution silicate residues (approximately 0.8-8.0 micrometers) revealed a larger contribution from dust thinner than previously thought.

The authors suggest that the role of silicate dust, along with soot and sulfur, may have blocked photosynthesis and withstood the shock winter long enough to cause a catastrophic collapse of primary productivity, setting off a chain reaction of extinction.
