Dinosaurs were not the only organisms that went extinct at the end of the Cretaceous period. C. More marine organisms went extinct during the Cretaceous than did dinosaur species. D. It is more important to understand how plankton and other marine organisms came to thrive during the Cretaceous ...
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. ...
Rock cores pulled from the famed Chicxulub crater off the coast of Mexico have revealed what the dinosaurs’ last day on Earth would have been like 66 million years ago. Leaving a crater in the Yucatán Peninsula more than six miles wide—or the size of San Francisco—the asteroid wiped ...
Um...well, we think an asteroid hit Earth, near the Yucatan Peninsula, in Mexico, and that wiped out all the dinosaurs. Professor: Right. I wouldn't say that we've got 100% proof, but there's very strong evidence that this is why that mass extinction occurred. Okay. But did you ...
Hidden below the waters of the Gulf of Mexico, the Chicxulub crater marks the impact site of an asteroid that struck Earth 66 million years ago. The most consequential outcome of this cataclysmic event was the fifth mass extinction, which wiped out about 80% of all animal species, including...
with some disastrous events.The most famous mass extinction(灭绝)was 66 million years ago,when it's widely believed that a meteorite(陨石)killed off the dinosaurs.A 110-mile-wide crater in Mexico with the same geological age supports this theory. Believe it or not,this wasn't the worst ...
A 110-mile-wide crater in Mexico with the same geological age supports this theory.Believe it or not, this wasn't the most cruel incident in our planet's history. That was when a surprising 96% of life was wiped out at the end of the Permian(二叠纪)period, 252 million years ago. ...
