How big did dinosaurs get and how long did they live? Until recently, paleontologists could only guess the maturity rate and lifespan of dinosaurs. Recent research involving microscopic analyses of the cellular structure of dinosaur bone has revolutionized our answers to these mysteries. Dinosaur bones contain growth rings, somewhat like the rings on a tree trunk, which reveal yearly periods of rapid and slow growth. Paleontologists studying T.rex found that an adult could weigh as much as 10,000 pounds and usually lived up to 28 years.
