The first Tyrannosaurus rex is believed to have hatched approximately 68 million years ago during the Late Cretaceous period. Fossil evidence suggests that T. rex roamed what is now North America, with its existence spanning from around 68 to 66 million years ago, just before the mass extinction event that wiped out the dinosaurs. However, the exact date of the first T. rex's hatch is not known, as it is based on geological and fossil records rather than a specific event.
