A massive meteore hit the earth to cause the extinction of all the dinosaurs including tyrannosaurus rex. No one has proven anything, but the meterite theory has pretty much been cancelled out of the plausibly theories. It is more likely that they evolved and formed birds or that the weather change caused them to die. Since someone redirected the question "How much does a Tyrannosaurus weigh" to this question, I will answer it here: Up to 6.8 metric tons (7.5 short tons).

∙ 11y agoYoung Ankylosaurus could have been killed by predators like Tyrannosaurus or dromaeosaurid dinosaurs, disease, starvation, or accidents. Adult Ankylosaurus had no predators, so they would have died from disease, old age, starvation, or accidents. As a species, however, Ankylosaurus was wiped out by the K-T Extinction Event. When a 6 mile wide asteroid impacted the Yucatan Peninsula, so much dust and ash was launched into the atmosphere that sunlight was blocked for months or years. This caused plants to die, which left herbivorous dinosaurs like Ankylosaurus to starve to death.
