Grand Canyon May Have Existed When T-Rex Roamed the Earth

Geologists, who have been fighting about the Grand Canyon’s age, now have evidence that suggests the bottom of one of the world’s most famous gorges is about 65 million years older than thought. Scientists from the California Institute of Technology and the University of Colorado at Boulder found data that may point to the formation being carved to near its modern depth 70 million years ago. That would date the canyon to the Late Cretaceous period when Tyrannosaurus Rex still roamed the earth before their demise about 5 million years later, according to a study published in the journal Science. The western canyon would have been carved around the same time as the dinosaur’s existence, according to today’s study. A previous study, from 2008, suggested parts of the eastern canyon were developed about 55 million years ago, a period that’s the dividing line between the Paleocene and the Eocene, when the first modern mammals emerged. The Grand Canyon, on the Colorado Plateau in northern Arizona, is 277 river miles long, up to 18 miles wide, and 1 mile deep. The Colorado River runs through it...more

So now it's clear:  The Grand Canyon was caused by overgrazing by dinosaurs and global warming. 

I would blame this dastardly display of sustainability ignorance on early cavemen.  I mean, why didn't they get together and adopt Agenda 1?  However, I can't blame man because...he didn't exist yet.

There must have been some Primates out there who wore boots and made a livin' off of T-Rex steaks and other dinosaur delights.  Talk about your Rocky Mountain Oysters!

And global warming you ask?  Well, if cow farts contribute to global warming just imagine the damage done when ole Tyrannosaurus Rex let loose.

I rest my case.
