Scientists are aiming to drill into the crater left by theasteroid that may have killed off the...Thompson, Ben
It was created by a 7.5-mile-wide (12 km) asteroid that hit Earth 66 million years ago. Though the crater is now partially on land, at the time of impact the Yucatan was under a shallow sea. The collision led to the extinction of 75% of species, including the nonavian dinosaurs. ...
Dinosaurs shared their last million years with modern creatures. Since more than just dinosaurs became extinct, reasons that only explain why dinosaurs died can be ruled out. For instance, there is one theory that disease caused the extinction of dinosaurs. But a disease could not have caused ...
FEMALE STUDENT: An asteroid hit Earth.Um...well, we think an asteroid hit Earth, near the Yucatan Peninsula, in Mexico, and that wiped out all the dinosaurs.MALE PROFESSOR: Right. I wouldn't say that we've got 100% proof, but there's very strong evidence that this is why that mass...
A 110-mile-wide crater in Mexico with the same geological age supports this theory. Believe it or not, this wasn’t the worst catastrophe in our planet’s history. That was when 96% of life was wiped out at the end of the Permian period, 252 million year ago. Scientists don’t know...
Earth’s Hidden Eighth Continent Is No Longer Lost The Ocean Can Remember for 20 Years, Study Says 14 Million Americans May Sink Within 76 Years Earth Has Tilted 31.5 Inches. That's Alarming. Gophers Saved a Lava-Destroyed Ecosystem

andsignificant C02 emission. The famous Cretaceous-Paleogene extinction event which wiped out dinosaurs is believed to be a result of an asteroid hitting the Earth. The actual meteorite impact crater was found in Mexico (Chicxulub crater) and strongly believed to be the main cause of the extincti...
there was also a crisis among the land plants, in addition to the disappearance of dinosaurs.So any event that can explain the destruction of the base of the food chain (plankton in the ocean, plants on land) can better explain what happened to organisms at the top of the food chain, ...
Although a majority of biologists are convinced that a mass extinction is underway on earth today, the human history with direct observatory data is too short to predict its future trends. At least five mass extinctions occurred during the Phanerozoic Eon, causing the rapid extinction of at least...
