The colossal impact event, which triggered a mass extinction event over much of Earth's land and ocean environments, also filled the present-day Gulf of Mexico with nutrients for at least 700,000 ...

Although an asteroid impact has long been the suspected cause of the mass extinction 66 million years ago, ... In the following decade, Chicxulub Crater was discovered in the Gulf of Mexico.

Around 66 million years ago, an asteroid between six and ten miles (10 to 15 kilometers) wide slammed into what is now the Gulf of Mexico, leaving behind a massive 90-mile-wide (150 kilometers ...

It would take another 10 years before samples from the Chicxulub crater were studied by Penfield. When he did, he found an unusually large amount of shocked quartz, as well as impact melt spherules.

The asteroid that created the Chicxulub Crater in the Gulf of Mexico is estimated to have been about 12km across. It gouged out a 200km-wide depression, and in the process set off mighty earth ...

The Chicxulub crater formed when a 7.5-mile-wide (12 kilometers) space rock traveling at around 27,000 mph (43,000 km/h) slammed into Earth, creating a roughly 124-mile-wide (200 km) bowl in what ...

Based on its apparent position in Earth’s geologic layer cake, it may have formed not long before or after Chicxulub — the 100-mile-wide chasm under the Gulf of Mexico excavated by a six-mile ...

About 66 million years ago, an asteroid slammed into the planet, wiping out all non-avian dinosaurs and about 70% of all marine species. But the crater it left behind in the Gulf of Mexico was a ...
