Tyrannosaurus's Fall From Grace


Tyrannosaurs were one of the most fearsome and largest carnivores of all time. Tyrannosaurs are part of the theropod family. They lived throughout western North America and Asia. Paleontologists have recently discovered a hip bone belonging to an ancestor of Tyrannosaurus. They found it at Dinosaur Cove in Victoria, Australia. Tyrannosaurs may have lived worldwide, and their remains or skeletons may be discovered in Africa, South America, and India. 

Tyrannosaurus was present from the beginning to the end of the dinosaur era. These animals actively look for opportunistic scavenging. Early tyrannosaurus was more agile due to its longer legs than other theropods. The early tyrannosaurids were elegant and trim. As time passed, the forest decreased, and the Earth's temperature cooled down after the Cretaceous period. These animals went down to further derivation. These animals were further divided into spinosaurus and carcharodontosauridaes. The genetic shift leads to the displacement of animals due to finding an environment that suits their needs.

The new bone came from dinosaur fossils that lived earlier in the Cretaceous period (around 110 million years ago) than the T. Rex (who lived around 70 million years ago). During this time, the continents gradually went from a single supercontinent to something we have today. Tyrannosaurs became extinct when an asteroid or comet the size of a mountain slammed into Earth, bringing a sudden end to the Cretaceous period.

Specification Of Tyrannosaur Teeth 

Tyrannosaur teeth are serrated teeth. They are considered the most significant tooth of any carnivorous dinosaur ever found. It was 12 inches (30 centimeters) long. These teeth were the upper hand for tyrannosaurs to kill the prey and slash the meat before gobbling. Research revealed a layered arrangement of tissues inside the teeth, which look like steak knives. Their teeth consisted of vital tissues consisting of dentine in them.

Strengths Of Tyrannosaurus 

Tyrannosaurus' powerful body stretched as long as 40 feet, from its snout to the tip of its powerful tail that weighed up to eight tons. Tyrannosaurus stomped across its territory on two powerful limbs. These dinosaurs likely preyed on other living animals, and sometimes they even ate one another. In contrast, paleontologists have known for a while that this dinosaur devoted significant portions of its brain to processing smell. Their robust snout also likely helped tyrannosaurus find mates and detect other predators.

Weakness Of Tyrannosaurus 

Tyrannosaurus had unexpectedly small arms, and the function of these little arms is a source of debate among paleontologists. Some believe the animal's arms were an evolutionary leftover, like the pelvic bones of a snake, or served non-predatory purposes like helping it grip a mate. Others argue that tyrannosaurus arms may have been adapted for "vicious slashing" at close quarters, given their ability to inflict deep wounds with four-inch claws. 


Tyrannosaurus skeletons were mounted as sleek-looking dinosaurs. However, paleontologists working with SUE at the Field Museum in Chicago figured out where the placement of a series of rib-like bones goes. These gastralia bones went under the ribs of the tyrannosaurus, on its belly, and aided in the dinosaur breathing. Adding these gastralia bones makes SUE have a bulging belly and widens its rib cage.

Tyrannosaurus had the most significant, robust, and potent skull compared to other theropod dinosaurs. It was specialized. Tyrannosaurus had dramatic skeletal changes as it grew from a hatchling into a full-grown adult. The skull starts very slenderly with a somewhat lengthy snout. However, as it aged, the skull became considerably more significant, the snout became blunt, and the jaws became very robust. Looking at an adult tyrannosaur skull and comparing it to other theropods tells us that the jaws would have been hefty.

In 2012, Bates did a study of the bite force of a human. The study was more accurate than the previous evaluation because they used "dynamic musculoskeletal models'' to imitate the bite forces of the disaster. Bates found juvenile tyrannosaurus had a small bite force, indicating a diet of small prey. At the same time, adult tyrannosaurus had a mighty bite force, much higher than other theropods. Their bite force was between 35,000 and 57,000 Newtons per tooth (up to 12,800 pounds of force per tooth) (Bates, 2012). Bates stated that 12,000 lbs are equivalent to an elephant sitting on a person!

In-Depth Life History 

There has been speculation that tyrannosaurs have been great caretakers of their nests. These tyrannosaurus generally attack animals smaller than them to prey quickly. Their newborns used to be ten times smaller than their parents and used to attack even small animals or eat up their remains. Therefore, these 2.5-foot offspring would likely hunt small mammals, insects, and lizards.

Juvenile tyrannosaur teeth are built strong to hunt down tiny dinosaurs, animals, and other reptiles. These young tyrannosaurs used to hunt combined to combat the larger prey for more food. Moreover, young tyrannosaurs used to compete with dinosaurs like dromaeosaurs such as Deinonychus.

The average life expectancy of a tyrannosaurus used to be around 25 years. These creatures grew faster after 13 years by attaining more robust bodies till their strength-oriented adulthoods.
