The largest and best-known member of the tyrannosaur group is Tyrannosaurus rex, often referred to as T. rex.12

Translating to "king of the tyrant lizards," this predatory dinosaur lived during the end of the Cretaceous Period, approximately 66 million years ago. A large adult T. rex could measure more than 12 to 14 meters (about 39 to 46 feet) in length and weigh between 4,000 and 7,000 kg (about 9,000 to 15,000 pounds). Notable specimens include "Sue," which measures 12.8 meters (42 feet) long, and "Scotty," estimated at 13 meters (42.7 feet) long and 8,870 kg (19,555 pounds).12

T. rex is characterized by a massive skull, powerful hind limbs, and significantly reduced forelimbs. While it was a formidable predator capable of biting through the bones of other dinosaurs, some scientists suggest it may have also engaged in scavenging.12
