Estimated 12 meters long
T. rex (type)
Late Cretaceous, 68-66 million years ago
Tyrannosaurus, also known as the “Tyrant Lizard,” is one of the most iconic and well-known dinosaurs of all time. It lived during the Late Cretaceous period, around 68 to 66 million years ago, in what is now western North America.
Tyrannosaurus was a large and powerful dinosaur, measuring up to 40 feet (12 meters) in length and weighing as much as 15,000 pounds (7,000 kilograms). It had a massive head with a powerful jaw that was lined with sharp teeth up to 12 inches (30 centimeters) long. Its forelimbs were small and weak in comparison to its large hind limbs, which were adapted for running and hunting.
Tyrannosaurus was a top predator of its time and likely hunted a variety of other dinosaurs, including hadrosaurs, ceratopsians, and other smaller theropods. Its powerful jaws and teeth were well-suited for crushing bone, which suggests that it may have been a scavenger as well, feeding on the remains of other animals.
The physical characteristics of Tyrannosaurus have been studied extensively, and many aspects of its biology and behavior are still the subject of ongoing research and debate. For example, there is some evidence that suggests that Tyrannosaurus may have been a pack hunter, while others believe that it was primarily a solitary hunter.
In popular culture, Tyrannosaurus has become one of the most famous dinosaurs, appearing in countless movies, TV shows, and other forms of media. Its distinctive appearance and fierce reputation have made it an enduring symbol of the world of dinosaurs, and it continues to capture the imaginations of people of all ages.
