Dinosaur fossils found in New Mexico are challenging the idea that when dinosaurs appeared on the scene some 235 million years ago, they quickly rose to dominate the landscape.
Buried among the dinosaur bones, a team led by UC Berkeley paleontologists discovered the remnants of the dinosaurs' predecessors, dinosauromorphs, that lived 15-20 million years after the first dinosaur showed up.
"It was very exciting because we knew this was a type of animal that no one thought you'd find anywhere at any time in North America," said paleontologist Randall Irmis, a graduate student at UC Berkeley and lead author of the study which appears today in Science.
The discovery means that dinosaurs didn't simply replace their ancestors. Instead, the two types of animals lived side-by-side and competed for resources for millions of years.
"It has shaken up the old theory," said Bill Parker, a paleontologist at Petrified Forest National Park who also studies dinosaurs. "Everything was nice and neat before."
Scientists thought dinosaurs evolved from the dinosauromorphs in South America. Then, they may have driven their predecessors to extinction by outcompeting them with their bigger, faster and stronger bodies. Or, their ancestors and other animals suddenly went extinct for another reason, and the dinosaurs took advantage of the newly empty ecological niches.
Either way, the belief was that by the time dinosaurs were roaming North America, the dinosauromorphs were long gone.
"Everybody thought those animals had gone extinct," Parker said. "I think people are going to be surprised."

Time to change the science books again!
Both derived from a common ancestor probably 100+ million years ago. Some physiology never changed: if you clip your dog's nails, you'll notice that the fronts grow twice as fast as the rears. Just like us!
Time won’t help at all, the probability of even a mycoplasma cell spontainously coming to life w/all the amino acids(about 400) to give it life is one chance in 10 to the 119,800th power and the time it would take(the age of the earth times 10 to the 119,800th power) still makes it impossible.
Evolution is a theory and thats all. It is sad that it is taught as fact in our schools and universities with no evidence to back it up. Someones best guess that science has turned into a religeon.
One would think you would know better by now.
I think them dinosauromorphs have been hiding in my basement all this time along with a heap of other stuff.
Another good reason to put off cleaning it.
It's easy to know everything when you know just about nothing, isn't it?
There are 20 standard amino acids used by most organisms to build proteins.
Woho....why we have a scientific moralist...
“It’s easy to know everything when you know just about nothing, isn’t it?”
Judgmental too, likes to cast the first stone!
Except that my suggested title is more accurate than yours...
Heck yes, except in the arena of science it goes, “Let he who is most qualified among you throw the first stone.” That would be me. :-D
“That would be me”
If you say so....
There was no global flood 4350 years ago.
Check my FR homepage for definitions, including the definition of "theory."
If you are this wrong on something so simple, why should we trust anything else you have said?
Or as they are better known, the dinobots...
Not if you were honest and paying attention.
Dude, it’s missing the hairy chest and gold chains. I lived the 70’s.
You fell into his trap. He'll just say that the evidence hasn't been found, yet. God always answers prayers-- either yes, no, or wait (which fits what happens when you pray to your toilet, too). Believers are always able to come up with ways to explain things that fit their beliefs.
But what will happen to our theology if we admit error?
Not my problem. You painted yourself into a corner and you can get yourself out.

Where are all the FACTS?
Interesting. I don’t see that this has much bearing on the inherent improbability of general evolutionary theory one way or the other.
But it could make a difference in the toy industry. Maybe by next Christmas we’ll be seeing stuffed purple dinosauromorphs in Toys “R” Us.
