how dinosaurs became extinct
Flash paper #3 Rebuttal to flash paper #2 In my last paper I wrote about the combination of a meteor strike and the release of millions of cubic feet of methane trapped on the ocean floor as a means to the extinction of the dinosaurs. However, this theory does not explain why frogs and reptiles, mammals and birds survived the extinction, but dinosaurs did not. My new theory is that dinosaurs died because they became too heavy to be supported by their weight. ... Then gravity increased allowing the dinosaurs to grow to gigantic proportions, and then sixty-five million years ago, gravity suddenly shifted back to what it is now.
