the extinction of the dinosaurs

In the New York Times article by Peter Brannen titled The Death of the Dinosaurs published on January 31, 2015, the author argued that the evidence for the extinction of the dinosaurs via climate change and massive volcanic activity explains the demise of these ancient creatures better than their demise caused by a "colossal fireball from heaven." http://nyti.ms/1yU55rg (http://dannyblasearthscience.blogspot.com/)

Dr. keller is a geologist at prinston who says that climate change is the reason the dinosaurs went extinct.

The father and son team made the theory that most people say is true, basically a meteor hit the earth and killed the dinosaurs.

Earth has had five major extinctions that we now of and that makes me feel worried that this can happen again which is not good.

Rocks in Texas, Tunisia tell Dr. Keller that warming episodes caused the extinction of the dinosaurs.


In my opinion the dinosaurs were killed by a meteor which led to volcanoes to erupt and kill the dinosaurs.
