Tyrannosaurus rex had a life span just under thirty years. They had a major growth rate increase during their teenage years. At about age twenty, a T-rex would have been mature.
T-rex! If you ask a 5 year old he will say T-rex. If you ask an 80 year old they will say tiger or T-rex.
Yes, if mosquitos that are preserved in amber that sucked the blood of a T-Rex could be harvested, the DNA sequence of the T-Rex could be extracted and replicated, and, combined with that of common frogs, could be used to clone a T-Rex. Source: Jurassic Park
