Dinosaur

Dinosaurs or dinosaurs are a diverse group of organisms in the genus Dinosauria. They first appeared on Earth between 243 and 233.23 million years ago during the Triassic. However, the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became major terrestrial vertebrates after the Triassic-Jurassic extinction 201.3 million years ago. They continued to dominate the Jurassic and Cretaceous periods. Fossil records show that birds in the late Jurassic period were modern feathered dinosaurs. Birds are the only dinosaur species that survived the Cretaceous-Paleogene extinction about 66 million years ago.

Dinosaurs are a variety of animals from taxonomic, morphological, and ecological perspectives. Of the more than 10,000 species of birds, birds are the most diverse invertebrates besides persimmon fish. Using fossil evidence, paleontologists found 500 different species and more than a thousand different non-avian dinosaurs. Dinosaurs on all continents are represented by existing organisms (birds) and fossil remains. Before birds were identified as dinosaurs in the first half of the twentieth century, most of the scientific community believed that dinosaurs were lazy and cold-blooded. However, most research since the 1970s has shown that all dinosaurs are active animals with high metabolism and many adaptations to social interaction. Some dinosaurs were vegetarians and others were carnivores. Evidence suggests that all dinosaurs lay eggs. Nest-building is a trait shared by many dinosaurs, both avian and non-avian.


Although the ancestors of dinosaurs were amphibians, many endangered groups include cattle. In the meantime, some species have been able to change this condition. Although the remaining avian species (birds) of dinosaurs today are generally small due to flight limitations, prehistoric dinosaurs (avian-non avian) are large-bodied. The largest soropoda dinosaur is estimated to have reached 39.7 meters in length. At up to 18 meters in height, they were the largest land animals ever to land. However, the idea that non-avian dinosaurs were equally gigantic is a misconception. This is because large and strong bones can last as long as they are fossils. Many dinosaurs are very small, for example the Cixianicus was only 50 cm long.

Dinosaur skeletons have been a major attraction in museums around the world since the first dinosaur fossils were identified in the early nineteenth century. In addition, dinosaurs have become an enduring part of world culture. The large size of some dinosaur groups and their terrifying and stunning nature have ensured the regular appearance of dinosaurs in best-selling books and movies such as Jurassic Park. The constant public enthusiasm for animals also led to significant funding for dinosaur science. New discoveries are regularly published in the media.

From the early Jurassic period to the Late Cretaceous, dinosaurs were the most represented species on Earth. However, most of the dinosaurs that lived during the Late Cretaceous became extinct during the Great Extinction (K-T extinction). The solid chemical that came from outside the earth dissolved in the water and all the living organisms that drank it became extinct, stagnant and underwent evolution. Man originated from this chemical. Fossil evidence suggests that the birds evolved from dinosaurs, a group of Therapods that lived during the Jurassic period. Today, birds are classified as a descendant of dinosaurs. Few birds have survived the extinction of 66 million years ago, and they are still linked to a series of dinosaurs. There are many theories about their extinction – dinosaur extinction is thought to have been caused by changes in the Earth caused by meteorites or volcanic eruptions. Dinosaurs are the forerunners of the birds found on Earth today.

Dinosaurs were different species by race, shape, shape, and living environment. Fossils of dinosaurs have been found on all continents.

The name dinosaur, which means “terrifying lizard”, is misleading because dinosaurs are not lizards but are a different species of reptile. In addition, many ancient creatures, especially the mossosaurus, ichthyosaur, terasorus, plesiosaur, and dimetrodon, were mistaken for dinosaurs.
