The question of whether Tyrannosaurus was an apex predator or a pure scavenger was among the longest debates in paleontology. Most paleontologists today accept that Tyrannosaurus was both a predator and a scavenger. Specimens of Tyrannosaurus rex include some that are nearly complete skeletons.
The largest species was Tyrannosaurus rex, the most massive known terrestrial predator, which measured over 13 metres (43 ft) in length [2] and according to most modern estimates up to 8.87 metric tons (9.78 short tons) in weight. [3] [4] Tyrannosaurids were bipedal carnivores with massive skulls filled with large teeth. Despite their large ...
Knowledge of Deinosuchus remains incomplete, but better cranial material found in recent years has expanded scientific understanding of this massive predator. Although Deinosuchus was far larger than any modern crocodile or alligator, with the largest adults measuring 10.6 meters (35 ft) in total length, its overall appearance was fairly ...
T. rex has been the single species of the genus Tyrannosaurus recognized since the dinosaur was first described in 1905. T. rex still reigns as the king of dinosaurs, according to scientists who ...
Daspletosaurus is closely related to the much larger and more recent tyrannosaurid Tyrannosaurus rex. Like most tyrannosaurids, Daspletosaurus was a large bipedal predator, with the average adult measuring 8.5–9 m (28–30 ft) and weighing 3 metric tons (3.3 short tons). However, the largest potential specimen measures around 11 metres (36 ft ...
Mounted skeletons of different age groups, Los Angeles Natural History Museum. The feeding behaviour of Tyrannosaurus rex has been studied extensively. The well known attributes of T. rex (its jaws, legs and overall body design) are often interpreted to be indicative of either a predatory or scavenging lifestyle, and as such the biomechanics, feeding strategies and diet of Tyrannosaurus have ...
Gorgosaurus (/ ˌ ɡ ɔːr ɡ ə ˈ s ɔːr ə s / GOR-gə-SOR-əs; lit. ' dreadful lizard ') is a genus of tyrannosaurid theropod dinosaur that lived in western North America during the Late Cretaceous Period (), between about 76.5 and 75 million years ago. [1]
Using a steel Tyrannosaurus rex skull, scientists learned that Tyrannosaurus could easily crush a small mini cooper. Scientists learn that Tyrannosaurus could run at 25 miles per hour Scanning an endo cast from a Tyrannosaurus rex skull, scientists theorize that Tyrannosaurus rex had a brain similar to that of a modern-day alligator.
