The Real Reason Dinosaurs Became Extinct

Washington, Nov 18 : Fossilized dinosaur droppings found in central India show sauropod dinosaurs may have fed on grass between 65 million and 71 million years ago, refuting the theory that grasses emerged long after the dinosaur era, a study said Friday.
An international team of researchers, including Vandana Prasad of the Birbal Sahni Institute of Palaeobotany in Lucknow, India, studied the dinosaur coprolites, or fossilized droppings, of 65 million years ago.
The researchers sent some photographs and samples to Caroline Stromberg of the Swedish Museum of Natural History, who spotted tiny particles of silica called phytoliths that have come from the grass family, including relatives of rice and bamboo and forage-type grasses, according to a report in the journal Science published Friday.
The discovery surprised scientists. The earliest grass fossils ever found could be traced back to about 55 million years ago. And the giant plant-eating sauropod dinosaurs were supposed to eat plants like ferns and palms, as they didn't have the special kind of teeth needed to grind up abrasive blades.
Scientists said the diversity of the grasses suggest that grasses must have originated considerably earlier, well over 80 million years ago.
The findings also suggest that rodent-like early mammals that roamed among the dinosaurs may have fed on grass. They had teeth looking like those of grass-eating animals today, but much smaller.
What would you expect them to eat...cows?
Didn't like dark meat...?
Now all those dioramas will have to have grass added to the ferns.
Grass is a gateway plant. Why do you think they are extinct?
Not in India! That cow could be someone's grandmother, ya know!
Q. What does a dinosaur eat?
A: Anything it wants.
He he he...
Uh Oh. Time for more backtracking and revisionism by evolutionists.
Them facts are stubborn things.
You say that as if welcoming fact-induced change to the ToE is a bad thing.
MOO!

But wait! I've been told by Creationists that Evolutionists do not want to talk about changes to the theory! Don't tell me that - GASP! - some Creationists *lie!*
"Time for more backtracking and revisionism by evolutionists."
Since evolution is science, it is subject to revision and changes. Unlike, oh I don't know, creationism?
