Long-necked Dinosaur

In a warm and humid Jurassic Period landscape lush with plant and animal life in what is now southwest Montana, an adolescent long-necked dinosaur was miserably sick with flu and pneumonia-like symptoms.

About 150 million years ago, a giant, long-necked dinosaur stomped on the ground in the midwestern US state of Wyoming and left behind what researchers said Tuesday is the largest dinosaur foot ever discovered.

Scientists have identified a new species of giant long-necked dinosaur whose ancestors likely crossed over to Australia around 105 million years ago from South America.

Scientists on Tuesday unveiled body weight estimates for an astounding 426 different dinosaur species using a formula based on the thickness of their leg bones, crowning the truly immense long-necked Argentinosaurus as the biggest of them all.

A fondly held belief about long-necked sauropods, the giant four-footed dinosaurs beloved of monster movies and children, is most probably untrue, a dino expert said on Wednesday.
