Tyrannosaurus

About Tyrannosaurus

Tyrannosaurus (scientific name: genus Tyrannosaurus) is a carnivorous dinosaur that lived in North America about 70 to 66 million years ago (Maastrichtian at the end of the Cretaceous period of the Mesozoic era).
It is a genus of large theropods.
It is also called Tyrannosaurus, Tyrannosaurus, Tyrannosaurus, Tyrannosaurus, etc.

It is extremely famous and considered to be the most well-known dinosaur, appearing frequently in various dinosaur-themed creative works such as “Jurassic Park.”

It is extremely famous and considered to be the most well-known dinosaur, appearing frequently in various dinosaur-themed creative works such as “Jurassic Park.” However, there are still many aspects of its ecology that remain unknown, and with the wide variety of new theories, it is also a dinosaur that is constantly under debate.

About Brachiosaurus

Brachiosaurus is a genus of Saurischia in the Brachiosauridae family that was distributed in the western part of the Laurasia continent approximately 154 to 153 million years ago (some say it lived as long as 112 million years ago).

With a body length (total length) of about 25 m and a height (head to head) of about 16 m, it was considered to be the tallest dinosaur until recently.

With a body length (total length) of about 25 m and a height (head to head) of about 16 m, it was considered to be the tallest dinosaur until recently. It was once speculated that it was the heaviest dinosaur, weighing 80 tonnes (or more), and that it lived in water such as ponds and lakes to support its weight, but it was discovered that because it did not have a diaphragm, water pressure would crush its lungs, making it impossible to breathe, disproving this theory.

About Pteranodon

Pteranodon is a species and genus of pterosaur that lived in the Late Cretaceous Period of the Mesozoic era.
It often appears in novels, comics, and movies themed around dinosaurs and pterosaurs, and is one of the most well-known pterosaurs in the general public, making it a representative and iconic presence.

The first fossils were discovered in the Smoky Hill Chalk Formation, belonging to the Late Cretaceous period, in western Kansas, USA, by paleontologist Othniel Charles Marsh and others in 1870.

On May 2, 1876, the first fossil skull was brought from the Smoky Hill River in the same area by fossil collector S. W. Williston.

About Triceratops

Triceratops was originally described in Something Strange in 1889 by Othniel Charles Marsh, and since then, numerous fossil specimens have been recorded, although no complete skeletons have been found.
Specimens representing every developmental stage from hatchlings to adults have been found. As a quintessential ceratopsid, it is one of the most popular dinosaurs, appearing in many media such as films and postage stamps.

Its mouth was pointed like a bird’s beak. Its skull had a large bony frill and three horns, and its large four-legged body resembled a modern rhinoceros, making it one of the most well-known dinosaurs. It was also one of the largest ceratopsians, measuring 9 meters in length and weighing 12 tons.

birth

230 million years ago is considered to be the latter half of the Triassic period of the Mesozoic era.

230 million years ago is considered to be the latter half of the Triassic period of the Mesozoic era. During this same period, dinosaurs as well as other large reptiles such as ichthyosaurs and pterosaurs are thought to have emerged.

extinction

The most likely explanation is the “meteorite impact hypothesis.” A meteorite about 10 to 15 kilometers in diameter struck Mexico at an angle of 60 degrees.

The most likely explanation is the “meteorite impact hypothesis.” A meteorite about 10 to 15 kilometers in diameter struck Mexico’s Yucatan Peninsula at an angle of 60 degrees toward the north-northwest.

The process of dinosaur evolution gives us an opportunity to contemplate the mysteries of life.

Dinosaurs, each with their own unique characteristics and ecology, thrived on ancient Earth. Their diversity and evolutionary process give us the opportunity to ponder deeply about the history of the Earth and the mysteries of life.
