If Crocodiles lived during the era of dinosaurs, why didnt other species live through the mass extinciton?
The K-T, or end of Cretaceous extinction wiped out many large animals, notably dinosaurs. Stephen Jay Gould once wrote an essay pondering the question of why large animals are especially vulnerable to mass extinctions. Now we know the answer. The dinosaurs were wiped out because a giant meteor fell to the earth 65 million years ago. The force of the impact thrown up a lot of molten rock into the atmosphere. These then rained down on earth, raising atmospheric temperature to lethal levels for most animals that were no land. At the same time, these hot molten rocks ignited world wide forest fires. Being large animals, dinosaurs have to run to escape forest fires. But because these fires were world wide in extent, the dinosaurs and other land animals have no place to run. Not only did the dinosaurs became extinct, there were some large mammals that were also wiped out. An entire group of birds, called the enantiornithine birds, also became extinct. Some birds survived, but they were not e
