How fast did dinosaurs grow, and how long did they live?

Just like groups of mammals, different dinosaurs lived and grew at different rates. All of our knowledge that we have about how fast dinosaurs grew, and how long that they lived, is really group dependent, depending on group of dinosaurs it is. Some of our best evidence comes from Tyrannosaurus, and Tyrannosaurus that we know that they reached adult size in seventeen years or around seventeen years. In the oldest member of Tyrannosaurus Rex that we know, the Sue specimen in Chicago which is just a little bit over twenty five years old. Obviously our sample is very small so it's highly likely that Tyrannosaurus lived longer than that, we just don't have the samples to show it.
