Overtime, weather and erosion eventually erased most of the visual evidence of this devastating impact, which wiped out an estimated 70 to 80 percent of all species on Earth, including the dinosaurs.
Theresult, scientists believe, was the mass extinction of 75% of species on Earth including the non-flying dinosaurs. The crater was discovered in the 1990s, but the idea that the K–Pg extinction was caused by an asteroid impact was proposed a decade earlier by a team that included the physics Nobel laureate Luis Alvarez. Anasteroid some six miles (10 kilometers) wide or bigger smashed into Earth and created the Vredefort Crater, in present-day South Africa, some 2 billion years ago, long before even the dinosaurs
Mostscientists agree a meteor impact, called Chicxulub, in Mexico’s Yucatan Peninsula, accompanied the extinction of the dinosaurs 65 million years ago. But until now, the time of the Great Dying 250 million years ago, when 90 percent of marine and 80 percent of land life perished, lacked evidence and a location for a similar impact event.
Asteroiddust found at Chicxulub Crater confirms cause of dinosaurs’ extinction. Although an asteroid impact has long been the suspected cause of the mass extinction 66 million years ago
Septem at 2:00 pm. For decades, scientists have vigorously debated whether an asteroid strike or massive volcanic eruptions ended the reign of the dinosaurs 66 million years ago

Hurtlingto Earth at some 45,000 miles an hour, the impact likely sent out a flash of energy that ignited landscapes within a 900 miles radius. “Mexico was on fire immediately,” Anderson says.
Hubblecaptures movie of DART asteroid impact debris Date: March 1, 2023 Sep. 18, 2019 — About 466 million years ago, long before the age of the dinosaurs, the Earth froze. The seas began to The impact: If a huge asteroid had struck Earth at the end of the Cretaceous, it would have flung off particles from the site where it hit. So, if the asteroid hypothesis were correct, we should find these particles at the impact Scientists agreed that the evidence was strong—dinosaurs had gone extinct and there was a widespread CNN—. The age of the dinosaurs ended 66 million years ago when a city-size asteroid struck a shallow sea off the coast of what is now Mexico. But exactly how the mass extinction of 75% of the

Aset of 50,000 artificial Earth impacting asteroids was used to obtain, for the first time, information about the dominance of individual impact effects such as wind blast, overpressure shock, thermal radiation, cratering, seismic shaking, ejecta deposition, and tsunami for the loss of human life during an impact event for impactor sizes between

J. Roughly 65.5 million years ago, a massive asteroid smashed into present-day Chicxulub, Mexico. The impact set fire to Earth’s surface. Dust and ash darkened the sky, sending the T3DJED.
