I'm of the mind that they were on their way to extincton

I agree.

The Earth used to be smaller, spun faster, and a higher oxygen content. Those things enabled the reptiles and mammals to grow to such extreme sizes. The Land masses might have been changing (moving up or down) and the oceans relocating much more than they do now.

Loss of breeding grounds, or feeding spots, and maybe viruses could have helped wipe them out. Over time, it became harder to carry their weight as gravity increased.

So... they went 'extinct'. Life is life. It just has different forms at different times to match the living conditions. Forms go extinct. Life doesn't.

The cave men driveing SUV's caused the dinosaurs to go extinct...geeze, get with it people..:O)

I agree that the earth is getting fatter...asked my grandkids why you always have to dig down to find ancient stuff...no answer....therefore I am right, the earth is fatter than it use to be.. Someone please find me wrong..:O)
