Plateosaurus is an ancient dinosaur from the Triassic period, which lived between 222 million and 200 million years ago. It was the first giant dinosaur to appear on Earth. Before the appearance of the Banosaurus, the largest herbivore had a body size as big as a pig, while the Banosaurus was much larger, with a body the size of a bus. It is an ancient dinosaur that lived 210 million years ago during the Late Triassic period. It has a body length of 6-8 meters, a height of 3.6 meters, and a weight of about 5 tons.

The Andean bald eagle is a massive bird species and one of the largest flying animals in the world. Because they are too large (weighing up to 15 kilograms at most), even a wingspan of 3 meters requires the same assistance to succeed. Therefore, this bird prefers to live in windy areas so that they can glide effortlessly in rising hot air currents. As their name suggests, Andean bald eagles are more common in mountainous areas, but some also live on coasts with strong sea winds, and even in desert areas with hot air currents. They are scavengers, so they always fly in high altitude to search for animal carcasses to feed themselves. I like to eat large animals.
