Question

Tyrannosaurus was about six meters long and it preyed upon other animals. What do you think about its classification - was it an amphibian, a reptile, or a mammal?
Can you call it a relative of Kangaroo? Yes/No.
Give a reason.

Answer 1

Hint: Carolus Linnaeus, a scientist who developed a system for categorizing and identifying animals based on their shared characteristics, defined the categories. Kingdom, phylum, class, order, family, genus, and species are the terms used to describe the different types of organisms (King Philip Came Over For Good Spaghetti).

Complete answer:
Tyrannosaurus is a genus of theropod dinosaurs belonging to the tyrannosaurid family. Tyrannosaurus rex (rex means "king" in Latin), commonly known as T. rex or T-Rex, is one of the most well-known of these large theropods. Tyrannosaurus roamed what is now western North America, on what was then known as Laramidia, an island continent.
Other tyrannosaurids had a smaller range than Tyrannosaurus. Fossils have been discovered in a variety of rock formations dating from the Upper Cretaceous Maastrichtian period (68 to 66 million years ago). Before the Cretaceous–Paleogene extinction event, it was the last known member of the tyrannosaurids and one of the last non-avian dinosaurs to exist.
The kangaroo belongs to the Macropodidae family of marsupials (macropods, meaning "large foot"). The term is commonly used to refer to the red kangaroo, as well as the antilopine kangaroo, eastern grey kangaroo, and western grey kangaroo, which are all members of this family. Australia and New Guinea are home to kangaroos.

Tyrannosaurus and Kangaroo are not related because Tyrannosaurus is a reptile and Kangaroo is a mammal.

Tyrannosaurus characteristics include:
1. A cold-blooded creature.
2. Scales can be horny and can be found all over the body.
3. They are females who lay eggs. The eggs have a leathery exterior.
4. The ventricles were partially divided, resulting in a three-chambered heart.
5. Dinosaurs ruled the earth back then, with a few herbivores and a few carnivores.
All of these characteristics are reptile-like.

Thus, Tyrannosaurus is not relative to kangaroo.

Note:
In warm environments, cold-blooded animals remain active and alert; in cold environments, they become very slow and lazy. Reptiles and amphibians, for example, are cold-blooded animals with no special adaptation mechanisms.
