"T. rex had explosive growth spurt as a teen, study says"
"NEW YORK (AP) â Here's a dinosaur finding that parents can appreciate: The
teenage Tyrannosaurus rex typically went through an explosive growth spurt,
gaining nearly 5 pounds a day."
"During that spurt, from ages 14 to 18, the creature picked up most of its
eventual adult weight of around 6 tons, new research indicates. It stopped
growing around age 20 and apparently died by age 30."
This is a new paper in tomorrow's Nature, one of the authors being Gregory
Erickson of Florida State University. There are some fine quotes in the
article from our own Tom Holtz.
