The fossilized remains of Sue, the most complete Tyrannosaurus rex skeleton in the world, on display at the Field Museum of Natural History, Chicago.
The Tyrannosaurus rex maintained a horizontal posture, with its body carried parallel to the ground. In this position, the tail was held off the ground to serve as a counterbalance to the weight of the rest of its body. This function was essential for the dinosaur to maintain stability and agility, particularly when it was navigating its environment or pursuing prey.12
