The trajectory of the asteroid thought to have killed the dinosaurs 66 million years ago was just right to cause maximum damage. A new study of Chicxulub crater in Mexico, wherethe asteroidstruck, has revealed that the angle and speed of the impact were probably in the perfect ra...

How does an asteroid impact change a planet's surface? How big is a meteorite before impact? How large was the asteroid that created Chicxulub crater? What characterisitics of a meteorite determine the impact crater? How large was the asteroid impact that killed the dinosaurs?
The popular belief is that an asteroid impact caused the mass extinction at the K-Pg (formerly K-T) boundary 66 million years ago. This is the mass extinction that killed off the non-avian dinosaurs along with 75% of species on Earth. However, in reality there is a raging scientific deb...
There are two main reasons crocodiles survived the asteroid that killed the dinosaurs. First, crocodiles can live for a very long time without food. Second, they lived in places that were the least affected when the asteroid hit Earth.
—Asteroid impact, not volcanic activity, killed the dinosaurs, study finds —Fiery meteor that doomed the dinosaurs struck at 'deadliest possible' angle —How did birds survive the dinosaur-killing asteroid? In 2007, a team of scientists led by Bill Bottke of the Southwest Research Institute (...
The scientists believe that the fossils discovered in Tanis were killed and entombed on the day a massive asteroid known as Chicxulub slammed into Earth 66 million years ago, marking the end of the dinosaurs reign and the advent of mammals. ...
In fact, there is strong evidence that this impact event represents the asteroid that killed the dinosaurs nearly 66 million years ago. How big was the asteroid that killed the dinosaurs? The asteroid responsible for the Chicxulub impact event was roughly 8 miles in diameter The location of ...
