Jurassic Park

Every year fossils of previously known and unknown dinosaurs are discovered. Argentinosaurus is the largest plant-eating dinosaur found to date: 90 feet tall, more than 120 feet long and weighing around 220,000 pounds. Bones of this creature - but not a complete skeleton - have been found.

Was such a giant free to wander without risk of attack by a meat-eating dinosaur? Since paleontologists believe the biggest carnivores hunted on their own - and none could match Argentinasaurus’ sheer size - did this behemoth have no predators?

Recent discoveries in Alberta, Canada and Patagonia, Argentina suggest that a meat-eating dinosaur larger than T-rex lived at the same time as Argentinasaurus. This giant (called Giganotosaurus), with a skull (scroll down 90%) bigger than a human, MAY have hunted in packs.

A group of such creatures (with their serrated teeth capable of ripping prey to shreds) may have been able to successfully kill an Argentinasaurus. To see a real-life battle between such Titans would have been like watching today’s science fiction.

No serious student of dinosaurs doubts that such major discoveries will continue. And, if that happens, paleontologists may soon discover a new "star" for the next Jurassic Park movie.
