With this evidence we can see that T-Rex was fully grown by the age of 28 and lived at least this long; however, we cannot determine if this is a good age for a fully grown T-Rex. As for the larger dinosaurs like Sauropods, estimates state that these giant beasts could have lived for as long as 100 years or more. In part, this incredible lifespan was due to the lack of predators that preyed upon it and an herbivorous diet which reduced the potential for conflict or injury while feeding.
There is only one known species of the dinosaur: Giganotosaurus carolinii. It lived from 99.6 to 97 million years ago, during the early Cenomanian stage of the Late Cretaceous Period, or about about 30 million years before T. rex. First described in a 1995 study in the journal Nature, Giganotosaurus was, at the time, thought to be the largest carnivorous dinosaur.
