Tyrannosaurus Rex is probably the most recognizable dinosaur around. More than 50 specimens have been identified. Several examples have been identified as juvenile Tyrannosaurus. This has given scientists the ability to document physical changes in T. Rex, like estimating it’s lifespan, and determining how quickly Tyrannosaurus would have grown. The smallest known individual known as the "Jordan theropod” is estimated to have weighed only 66 pounds / 30 kg and was only 2 years old when it died.
