Summary

SNOWBIRD, UTAH-- A detailed look at the bones of a species of giant dinosaur, described here earlier this month at the annual meeting of the Society of Vertebrate Paleontology, suggests that these hulking beasts could grow to full size--tens of tons and longer than a tractor-trailer--in just a decade. The finding makes sense to paleontologists, because hatchlings wouldn't survive long if they grew slowly like other reptiles, due to the threat of predators and the dangers of living with a 30-ton mother.
