And, the answer for the the question is :
Explanation:
You should count your lucky stars that you weren’t around during the late Cretaceous period, when Tyrannosaurus rex still ruled the Earth and was at the top of the food chain. Before becoming extinct 65 million years ago, these two-legged predators called the river basins of North America home. These colossal carnivores reached lengths of 40 feet, stood between 15 and 20 feet tall, and made the largest and most dangerous predators of today look like children playing in the yard. The beast had abnormally short arms that were presumably employed to hold down its victims. While its back legs were huge and muscular for hunting down prey, the beast’s front legs were disproportionately small and weak. The T-rex needed a lot of calories to sustain all that power, but lucky for them, they had a giant jaw that was four feet long so they could shovel those calories right in. With each bite, the powerful jaw could rip through bones and muscles, making it easy to penetrate thick hides.
The Tyrannosaurus rex, often referred to as T. rex, is one of the most iconic and well-known dinosaurs in history. This fearsome predator roamed the Earth during a specific period in the distant past. The Tyrannosaurus rex lived during the Cretaceous period, which spanned from approximately 145 million to 66 million years ago. In this article, we will explore the Cretaceous period and delve into the fascinating world in which the mighty T. rex thrived.
The Cretaceous period was the last period of the Mesozoic Era, also known as the Age of Dinosaurs. It followed the Jurassic period and preceded the Paleogene period, which marked the beginning of the Cenozoic Era. Lasting for approximately 79 million years, the Cretaceous period was a time of significant geological and biological changes on Earth.
During the Cretaceous period, the continents were arranged differently than they are today. They were still in the process of separating into the familiar shapes we recognize today. The supercontinent Pangaea had already split, giving rise to the northern landmass called Laurasia and the southern landmass known as Gondwana. These landmasses were surrounded by vast oceans, and the climate was generally warmer than in previous periods.
The Cretaceous period was characterized by diverse and flourishing ecosystems. It witnessed the emergence of numerous new groups of organisms, including flowering plants, insects, birds, and marine reptiles. Dinosaurs continued to dominate the land, with various species occupying different ecological niches. Among them, the Tyrannosaurus rex emerged as one of the most formidable and apex predators of its time.
The Tyrannosaurus rex, commonly abbreviated as T. rex, existed during the latter part of the Cretaceous period, specifically in the Maastrichtian age, which occurred from approximately 72 million to 66 million years ago. This period represented the final stage of the Cretaceous period before the mass extinction event that wiped out the dinosaurs and many other forms of life.
The T. rex was a massive carnivorous dinosaur known for its large size, powerful jaws, and sharp teeth. It stood up to 20 feet tall and could reach lengths of over 40 feet, making it one of the largest land predators in history. Its robust build, muscular limbs, and keen senses allowed it to hunt and take down prey effectively.
The Cretaceous period came to an abrupt end with a catastrophic event known as the Cretaceous-Paleogene (K-Pg) extinction event. This event, which occurred approximately 66 million years ago, marked the demise of the dinosaurs, including the Tyrannosaurus rex. It is widely believed that a combination of factors, including a large asteroid impact and volcanic activity, contributed to the mass extinction.
The impact of the asteroid, which struck near the Yucatán Peninsula in modern-day Mexico, caused widespread devastation. The resulting dust and debris in the atmosphere blocked sunlight, leading
