BOMBAY, India - U.S. and Indian scientists said Wednesday they have discovered a new carnivorous dinosaur species in India after finding bones in the western part of the country.

The new dinosaur species was named Rajasaurus narmadensis, or "Regal reptile from the Narmada," after the Narmada River region where the bones were found.
The dinosaurs were between 25-30 feet long, had a horn above their skulls, were relatively heavy and walked on two legs, scientists said. They preyed on long-necked herbivorous dinosaurs on the Indian subcontinent during the Cretaceous Period at the end of the dinosaur age, 65 million years ago.
"It's fabulous to be able to see this dinosaur which lived as the age of dinosaurs came to a close," said Paul Sereno, a paleontologist at the University of Chicago. "It was a significant predator that was related to species on continental Africa, Madagascar and South America."
Working with Indian scientists, Sereno and paleontologist Jeff Wilson of the University of Michigan reconstructed the dinosaur skull in a project funded partly by the National Geographic (news - web sites) Society.
A model of the assembled skull was presented Wednesday by the American scientists to their counterparts from Punjab University in northern India and the Geological Survey of India during a Bombay news conference.
Scientists said they hope the discovery will help explain the extinction of the dinosaurs and the shifting of the continents how India separated from Africa, Madagascar, Australia and Antarctica and collided with Asia.
The dinosaur bones were discovered during the past 18 years by Indian scientists Suresh Srivastava of the Geological Survey of India and Ashok Sahni, a paleontologist at Punjab University.
When the bones were examined, "we realized we had a partial skeleton of an undiscovered species," Sereno said.
The scientists said they believe the Rajasaurus roamed the Southern Hemisphere land masses of present-day Madagascar, Africa and South America.
"People don't realize dinosaurs are the only large-bodied animal that lived, evolved and died at a time when all continents were united," Sereno said.
The cause of the dinosaurs' extinction is still debated by scientists. The Rajasaurus discovery may provide crucial clues, Sereno said.
India has seen quite a few paleontological discoveries recently.
In 1997, villagers discovered about 300 fossilized dinosaur eggs in Pisdura, 440 miles northeast of Bombay, that Indian scientists said were laid by four-legged, long-necked vegetarian creatures.
Indian scientists said the dinosaur embryos in the eggs may have suffocated during volcanic eruptions.
After looking at the link, it's one I've seen before. It's not convincing: the Cocconino Sandstone is still very much a desert sandstone.
Thank you for that information, but since that wasn't the sentence which triggered the non-compliance notice (and the portion to which Physicist refers to as namecalling), your feelings about that sentence are a diversion from the actual matter being discussed.
The portion of the post which was found objectionable was already highlighted in an earlier post, it looks as if you missed it.
Why are they in the wrong layer? Ostracoderms like Anatolepis were the earliest known true vertebrates and have been known for over 100 years.
Good idea. That would be totally indefensible.
The geological column is frequently not in the right order.
Also indefensible. The only "out of order" situations commonly encountered are easily recognizeable extreme warping and displacement along fault lines.
Well, the universe can also be said to have always existed whereas 'always' means for all points in time that make sense. So 'before the big bang' makes as much sense as 'north of the north pole' (thanks to Physicist for this analogy).
You are also mistaken to think that the big bang is some kind of explosion which of course it is not. An explosion takes place within space but the big bang is the expansion of space itself.
Of course I'm only a layman in this regard but if you don't believe me we have a physicist here (just lurking behind the corner) who you can ask and who is much better at explaining these things than me.
I will. It will leave some things hard to explain, but I'll try to figure out a way.
I see nothing wrong with that statement, either. I don't see where you're going with this.
I'm not going anywhere with it. I am dropping discussion of that statement.
Some do, some don't. Charles Darwin was entirely ignorant of Big Bang cosmology, but that in no way hampered his insight.
Therefore, it is relevant where the "bang" came from. Whether it was an "explosion" or a sudden appearance of something from nothing that made a bunch of hot stuff and spun a bunch of stuff around (stuff, of course appearing out of nowhere) is kinda irrelevant. The theory does not make scientific sense.
To me it makes perfect sense. When you say that it doesn't make scientific sense, do you mean that you don't understand it, that you don't like how it sounds, or that the math doesn't work out?
