New evidence suggests sulfur's role in dinosaur extinction was overstated

Asteroid impact sulfur release less lethal in dinosaur extinction

Previous studies have posited that the mass extinction that wiped the dinosaurs off the face of the Earth was caused by the release of large volumes of sulfur from rocks within the Chicxulub impact crater 66 million years ago. A new study questions this scenario. Using groundbreaking empirical measurements of sulfur within the related Cretaceous-Paleogene (K-Pg) boundary layer, the international team has demonstrated that the role of sulfur duri…

What Killed The Dinosaurs? New Study Suggests We’ve Got One Key Element Wrong

New evidence suggests sulfur's role in dinosaur extinction was overstated

Approximately 66 million years ago, the Chicxulub asteroid, estimated to be 10–15 kilometers in diameter, struck the Yucatán Peninsula (in current-day Mexico), creating a 200-kilometer-wide impact crater. This impact triggered a chain reaction of destructive events, including a rapid climate change that eventually led to the extinction of the non-avian dinosaurs and, in total, about 75% of species on Earth.

It is generally believed that dinosaurs and other animals died out about 66 million years ago due to the fall of the Chicxulub asteroid, which resulted in a significant sulfur eruption, which led to a harsh and prolonged “shock winter”. However, the new study calls into question scientists' previous ideas about the scale of the disaster. RBC-Ukraine (Styler project) writes about this with reference to an article in the journal Nature Communicati…

An asteroid impact caused the extinction of the dinosaurs 66 million years ago. However, sulfur aerosols were not the main reason for the global cold phase that followed.
