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.

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

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…

Asteroid impact sulfur release less lethal in dinosaur extinction

Paris, France (SPX) Jan 17, 2025 
Approximately 66 million years ago, a massive asteroid known as the Chicxulub impactor struck the Yucatan Peninsula in present-day Mexico. Measuring an estimated 10 to 15 kilometers in diameter, the asteroid left a colossal 200-kilometer-wide crater. This event triggered rapid climate changes that ultimately caused the extinction of non-avian dinosaurs and about 75% of Earth's species. A signifi

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…

Принято считать, что динозавры и другие животные вымерли около 66 миллионов лет назад из-за падения астероида Чиксулуб, в результате которого произошло значительное извержение серы, повлекшее суровую и длительную "ударную зиму". Однако новое исследование ставит под сомнение предыдущие представления ученых о масштабах катастрофы. Об этом пишет РБК-Украина (проект Styler) со ссылкой на статью в журнале Nature Communications.

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

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.

Extinction of the dinosaurs: Sulfur is not the main reason

Previous studies claim that the mass extinction that wiped the dinosaurs off the face of the Earth was caused by the emission of large amounts of sulfur. A new study questions this scenario.

Eerdere studies beweren dat de massa-extinctie die de dinosauriërs van de aardbodem veegde, werd veroorzaakt door de uitstoot van grote hoeveelheden zwavel. Een nieuwe studie stelt dit scenario ter discussie.

Chicxulub Asteroid Impact Sulfur Release Was Less Lethal In Dinosaur Extinction - Astrobiology

Approximately 66 million years ago, the Chicxulub impact event dramatically shaped the course of Earth’s biological history. The asteroid, known to have a diameter between 10 and 15 kilometers, crashed into what is now the Yucatán Peninsula in Mexico, creating a colossal 200-kilometer-wide crater. This event not only marked the violent end of the non-avian dinosaurs but also initiated a global ecological crisis. An estimated 75% of Earth’s speci…
