WASHINGTON – Imagine dinosaur terrain – full of ferns and palms, right? Better add some grass to that picture. A new discovery debunks the theory that grasses didn't emerge until long after the dinosaurs died off. Fossilized dung tells the story: The most prominent plant-eating dinosaurs were digesting different varieties of grass between 65 million and 71 million years ago, researchers report Friday in the journal Science. Advertisement Click Me! The earliest grass fossils ever found were about 55 million years old – from the post-dinosaur era. It's a big surprise for scientists, who had never really looked for evidence of grass in dino diets before. After all, grass fossils aside, those sauropods – the behemoths with the long necks and tails and small heads – didn't have the special kind of teeth needed to grind up abrasive blades. "Most people would not have fathomed that they would eat grasses," noted lead researcher Caroline Stromberg of the Swedish Museum of Natural History. Stromberg and a team of paleobotanists from India analyzed sauropod dung – the scientific term is coprolites – found in central India. The coprolites contained microscopic particles of silica called phytoliths, which form inside plant cells in distinctive patterns that essentially act as a signature. Amid the expected plants were numerous phytoliths certain to have come from the grass family, report Stromberg and Vandana Prasad of India's Birbal Sahni Institute of Palaeobotany. They included relatives of rice and bamboo and forage-type grasses. They didn't eat a lot of grass, the evidence shows. But grasses must have originated considerably earlier, well over 80 million years ago, for such a wide variety to have evolved and spread to the Indian subcontinent in time to be munched by sauropods, they concluded. "These remarkable results will force reconsideration of many long-standing assumptions" about dinosaur ecology, wrote Dolores Piperno and Hans-Dieter Sues of the Smithsonian Institution's National Museum of Natural History in an accompanying review. Beyond the great curiosity about dinosaur life, the discovery has implications about the coevolution of this huge plant family – there are about 10,000 separate grass species – with other plant-eaters, Piperno explained. Indeed, a mysterious early mammal that roamed among the dinosaurs had more suitable teeth for grazing, raising the possibility of an early adaptation, the researchers note.

Once again the word of God is proved correct. The so called scientists need another revision in their junk science books. Creationism is correct. Evolution is disproven junk science.
So what this is saying that ALL dinosaurs were grass eaters.. Now consider this.. if God created them then would He not have created them perfectly? Why would God give some dinosaurs canine teeth which would enable them to eat meat best rather than teeth that would make them eat grass in not the most efficient way? Does this say God made an error? Apparently their is grass in their shit. So I guess their teeth worked fine. With my teeth I can eat meat or vegetables.
Critters have differing ways of collecting grass: some chomp it off, while others pull it out. There are also different ways of digesting said grasses. Who knows how many tummies the dinos possessed?
Interesting, considering that you've previously argued that the Earth is only 6000 years old.
And I'm optimistic. See, I think you can be realistic and optimistic at the same time. I'm optimistic we'll achieve -- I know we won't achieve if we send mixed signals. I know we're not going to achieve our objective if we send mixed signals - gwbush
Well just like carnivores today, they eat the stomachs and the intestines of
their quarry that contains vegetable matter.. so their dung would contain
remains of vegetable matter just as their prey.
Who knows how many tummies the dinos possessed? I suppose that the fossils reveal that they had vegetable matter in their stomachs or dung.. ?
;-) So it seems. I'm not sure why anyone would find it odd that they liked their veggies: my dogs enjoy a breakfast mix of green beans, carrots, brown rice, small red beans, black beans, walnuts, almonds, and pine nuts which I cook in chicken broth harvested from boneless, skinless chicken thighs. Then in the afternoon we'll enjoy either raw carrots, strawberries, bananas, or pineapple pieces. In fact, one of them is barking at me right now to alert me that it's time for the afternoon snack.
My dog loves oranges.. if you eat an orange you may as well know at least half of it is hers.. :P
My Mom used to have a cat that ate olives.

They proved the dung had grass matter in it. They did not prove their point on the age. They are still wrong on the age. Radio carbon dating and other dating methods have been proven wrong. They use assumptions and circular reasoning.
Whatever, I suggest you read the article again. It doesn't say a damned thing about ALL dinosaurs eating grass. The only contention among scientists is when grasses first appeared.

If some dinosaurs ate meat, it wouldn't surprise me. Afterall after the flood the world was changed. The bible makes that clear.
See comment 13. Grass was on the first day if my memory serves me correct. Certainly in the first few days. (less then 6).
They're are racoons here that rain the trash.. they get leftover pizza and pick off the olives! LOL
Absolutely, they needed something for Dionysis to throw up on...

I'm surprised they stop at the olives, racoons will eat just about anything.

LOL!
Its so weird.. the pizza was gone.. they left the olives in the box! But of course they left the box on the ground.. trashy raccoons..
On a more serious matter. What is your position? Are you a darwinist to the core? Are you not sure and open? A mix? What?
I don't like olives. Perhaps I evolved from a raccoon.
AHA!! the behemoths with the long necks and tails and small heads – didn't have the special kind of teeth needed to grind up abrasive blades. "Most people would not have fathomed that they would eat grasses," noted lead researcher Caroline Stromberg of the Swedish Museum of Natural History.
Hmm not so sure about that.. Hmm not so sure about that.. It's a big surprise for scientists, who had never really looked for evidence of grass in dino diets before. After all, grass fossils aside, those sauropods – the behemoths with the long necks and tails and small heads – didn't have the special kind of teeth needed to grind up abrasive blades. Both are from the article, whats your point? I can't see the image you linked real clear either.
Okay here's a link.. look at the differences..
Whoa. In it's kitty martini? Cheers, Daks.
The really laid back dino's smoked it.
Ah.. I get it.. they got the munchies .. it wasn't evolution at all it was the grass :P
LOL! That's right, they got the munchies then went to sleep, they didn't even see the big one coming....now they're extinct. See what smoking dope will get ya..
Yeah..betcha they saw the blast and said .. Awesome!! .. look at the pretty lights. :P
LMAO...yeah thats the ticket.
I'm an atheist, so obviously I think all creations myths are equally silly, therefore equally valid, comparatively speaking. I don't care if they teach I.D. in public schools as philosophy or religion, but I swear to Odin I'll get my machete and hack to death the first teacher that tries out that material in a Hoosier public school. Well, I'll take a run at them and give them a good fright anyway. Who am I kidding, I'm too busy for all that. It seems obvious to me that the Earth has been around more than 6000 years just from looking at the Grand Canyon. I don't care what people believe, I care about the money they've taken from me to convince others that their belief is the correct one. I also get more than a little cranky when people say I'm evil or dull witted, or even some sort of socialist for having the worldview with which I was born. The people that think I'm a socialist are the funniest.
And I'm optimistic. See, I think you can be realistic and optimistic at the same time. I'm optimistic we'll achieve -- I know we won't achieve if we send mixed signals. I know we're not going to achieve our objective if we send mixed signals - gwbush
I think the Grand canyon is marvelous proof of the flood. It was created rapidly. Think of water rushing through soft dirt on a very large scale.
My daughter had a cat that loved cantalope. The few times he was able to get out of her house, or mine, for that matter, she'd get cantalope and entice him out of his hiding or nesting or roosting place with it. Mine, her Tuffy's brother, would eat lettuce.
LOL......
She's a character.. will not stop when there's an orange in the area.. there is no way you can possibly ignore her... bananas too but she's worse with an orange than she is with any type meat or anything else for that matter.. weird isnt it?
Why would God want His perfect world changed? More important, why would God make so many stupid people, who's lives at best are spent in service to tackier creatures?

Re teeth.. Back when Mt. St. Helens erupted in the 80s, I contacted our vet to see what, if anything, to do with our livestock (cattle). Dogs and cats were kept in doors. He said the ash fallout would play hell with their teeth; cause them to grind down rather quickly. We wound up feeding our livestock under a heavy canopy of tree cover. Trees had bloomed out their leaves; grasses weren't up enough in the pastures to turn them in there; so we continued to feed hay. Even at that, they were covered in ash. That damn stuff was able to sift through anything and get in the house. Back to teeth..........any volcanic activity spewing ash could lay on grass or other forage. And when consumed....well.....
Our critters provide us much pleasure (?). I have a friend whose little pug delights in eating cigarettes! I learned that the hard way that you don't keep a pack of cigarettes in the side pocket of your purse.....2x that little witch ate half a pack and demolished the rest to where they were unsmokable. That was back when I smoked....about 6 months before I quit.
