Extinction of the Dinosaurs

The article The Death of the Dinosaurs published by The New York Times. The author is Peter Brannen on Jan 31, 2015. This is talking about 2 hypothesis that explained how the dinosaurs extinct in many many years ago. And this is the link: http://nyti.ms/1yU55rg.


For along time ago, the dinosaurs were extinct. One of the first hypothesis explained what happened that time is from geologist Gerta Keller of Princeton. These dinosaurs were killed not by the lava itself, but by the environmental catastrophe unleashed by the volcanic gases. It was the end time of global warming, acid raining and acidifying oceans that might sound familiar today as vast body of scientific research warns us of our own developing ecological crisis.


Another hypothesis is a luckless tyrannosaur looking over its shoulder as a fireball from heaven bears down on the horizon, the monster's death by vaporization imminent.

The planet has endured five major mass extinctions in which most of its fauna was wiped away in a geologic eye blink. And when I know this, actually, I did not feel anything. Scared? No! It could happen again in this world where we are living. Nothing is last forever. Human will die in someday, no one can run from the death.

Dr.Keller then points to rocks in Texas, Tunisia and elsewhere that indicate warming episodes of at least 7 degrees Fahrenheit it under 10,000 years, with acidifying oceans that killed all but the hardiest life-forms, which then thrived for millenniums.

In my opinion, I believe that the hypothesis of Dr.Keller is the best way to explained the death of the dinosaurs. Because she proved that at least 7 degrees Fahrenheit in under 10,000 years, with acidifying oceans that killed all. But according to many results we had, it's still fragile olive branch in a field where few have been extended in recent decades.
