A new dinosaur has been found which is bigger than T-Rex, sleeker, more agile and has teeth designed for slicing flesh rather than crushing bones. Eeeekkk mummy!!

Meat-Eating Dinosaur Was Bigger Than T. Rex (http://news.nationalgeographic.com/news/2006/04/0417_060417_large_dino.html)

Skeletons of a huge, meat-eating dinosaur that overshadows Tyrannosaurus rex have been discovered in Argentina.

The newly revealed species is one of the biggest carnivores ever to have walked the Earth, dinosaur experts say.
At least seven of the animals were uncovered together in a mass fossil graveyard in western Patagonia, a region famous for giant-dinosaur remains.

Living some 100 million years ago, the largest specimen was more than 40 feet (12.5 meters) long.

Researchers say the new species, named Mapusaurus roseae, is possibly even larger than its close relative Giganotosaurus, which in 1995 took T. rex's crown as the world's biggest known carnivorous dinosaur.

The find is also one of the first to suggest giant meat-eating dinosaurs lived in groups.

Renowned dinosaur hunter Rodolfo Coria, professor at the Carmen Funes Museum in Plaza Huincul, Argentina, found the fossils in the foothills of the Andes mountains.

Coria and fellow paleontologist Philip Currie of the University of Alberta in Canada describe the find in the latest issue of the journal Geodiversitas.

Mass Grave

While more than matching T. rex for size, Mapusaurus appears to have been a sleeker, more agile predator, with teeth designed for slicing flesh rather than crushing bones.

Coria says the new dinosaur's skull is longer than T. rex's.

"The lower jaw is also more delicate in Mapusaurus, and its teeth are thinner and sharper—they are just like knives," he added.

What's more, evidence from the fossil site points to Mapusaurus being a pack hunter, the researchers add.

Don Lessem, an author specializing in dinosaurs, took part in the fossil dig. "This could be the nastiest gang of killers ever found," he said.

Other dinosaur experts say the discovery sheds valuable new light on the most fearsome land predators ever known.


Cue a remake of Jurrasic Park?

Did it eat its own placenta?you will probably find that the male of the species ate other's offspring. Sounds amazing. But then I think there are still loads of species still to be disovered if you think of how large parts of the world are that were land and now under ice or sea during the Jurrassic

"The burial is formed 100 percent by Mapusaurus bones," he added. "The chances they had been deposited randomly are extremely low."

What they are missing is there is an absolutely massive creature that used to eat these things like popcorn :eek: .

All they've found is it's bathroom!

Sounds to me like they either all died as one unit , that fits the pack hunting(the difference I believe T-Rex did not only went in pairs) so now they will have to work out what killed them all together was it that cloud or as has been suggested a super dinosaur, which could be interesting

Uuuummm, only mammals produce young through eggs developed in a uterus with placental attachment. Dino's weren't mammals (otherwise they'd probably still be around) :}

Built one when I was at primary school. Made it out of wire and papier
mache, that was back in the early '50s.

Must almost be as old as the real thing by now!! But I survived.

Ah! There goes Fred Flintstone!!! :p :p

The intact remains of a T-Rex sold at an auction for a little over $8,000,000.00 USD.:eek:

I wonder what this lot will be worth?:suspect:

A super dinosaur built in lab out of parts from lesser dinosaurs?

The one that is scary is the one that killed that lot.
