If you think of something like an eagle or raven, they live for 20-30 years, and that would probably have been the lifespan of a T. rex.” The largest and best-preserved T. rex, in the Field Museum of Chicago, is thought to have lived to almost 29 years, although it would have achieved adult size after 20 years.
