Tyrannosaurus Rex Facts: Extinct Animals of the World

The tyrannosaurus, which means “tyrant lizard”, is a large theropod that inhabited the present western North America, in the then continental island of Laramidia. It had a wider range, with its fossils discovered in a variety of places including rock formations. The tyrannosaurus was the last known member of the tyrannosaurids. It was the largest carnivore in its environment and one of the largest known land predators. It is believed that tyrannosaurus rex is believed to have the greatest bite force among terrestrial animals. The dinosaur was most likely an apical predator, although some researchers suggest that it was primarily a scavenger.

Product description

Tyrannosaurus was one of the largest land animals. The largest specimen of the Field Museum of Natural History, nicknamed Sue, measured 40 feet long and 12 feet tall at the hip. His weight was estimated between 8.3 and 14 metrics when he was alive. The mass of an adult tyrannosaurus varied widely over the years from 4.5 to 7.2 metrics with modern measurements ranging from 5.4 to 8 tons. The neck was short and muscular to support the heavy head and formed an S-shaped curve like most theropods.

The Tyrannosaur rex had two clawed fingers and another small metacarpal on the forelimbs. The hind limbs were longer in proportion to the body size of most theropods. The tail was relatively long and heavy and sometimes contained vertebrae 40, to help balance the head and trunk. Most of the skeleton on the head was empty to compensate for its immense size. T. rex may have had feathers in some parts of the body. At one point the young man could have been feathered and freed of feathers, taking only the scales as he grew larger.

Feeding strategies

Several studies show that T .rex may have had the strongest force among the terrestrial animals that ever lived. He had a biting strength of 18 out of 23. He could bite with a force of about 8,000 pounds when feeding, exerting pressure of about 430,000 pounds per square inch with his teeth. The debate on whether the tyrannosaurus was a scavenger or a predator still continues. Some researchers have associated Tr ex with its close relative, Gorgosaurus, who was a pure scavenger. Other researchers claimed that he was a predator and that he had only recovered or stolen another predator’s killing when he had not had the opportunity. There has also been some evidence of cannibalism among the T. rex.

Locomotion

The debate on the locomotive ability of the T. rex is centered on its ability to turn and on the speed in a straight line it had. It may have been slow to turn, taking about two seconds to make a 450 shift. The cause of the inability to run fast was attributed to rotational inertia since most of its weight was far from its center of gravity. The T. rex may have produced a maximum speed ranging from 25 mph to 45 mph. Recent researchers do not support faster speeds of 25 mph. However, no trace of a race was found, with other researchers believing that it was never executed
