    T. rex was around for 20 million years or so, I’d say they passed for long enough to be considered successful. Despite the tiny arms.

      I think that’s been narrowed down to about 2 million years. But that got cut short by a mass extinction event, so it’s hard to say how long they would have lasted otherwise.
