T-Rexes inhabited places that were open and teeming with prey, forests, and areas near rivers.
T-Rexes were suited to their environment, especially when it was hot. To prevent overheating while using its massive jaws to smash its prey, the T-Rex had vents in its head to help its brain stay cool.
T-Rexes common ancestor are Daspletosaurus torosus.Anagenesis, the progressive transformation of an entire species, is how T-Rexes developed from Daspletosaurus torosus.
Scientists can tell what bones were close to one other and how the joints functioned due to the fossil records of the T-Rexes. They can rebuild the dinosaur and its movements using this knowledge.
The first skeleton of Tyrannosaurus rex was discovered in 1902 in Hell Creek, Montana. T-Rexes had a life expectancy of around 28 years. National Geographic stated, "what we know about this tyrannosaur is constantly evolving." For starters, Fossils provide a direct connection to the lifestyles, environments, and climatic conditions of the past.
