Dinosaur information

Dinosaurs areMesozoic EraA type from the period (230 million years ago)ReptilesThe depiction of most dinosaurs is of robust limbs, long tails, and massive bodies. They primarily inhabited forested areas or open plains along lake shores (or coasts).

In 1841, the British scientistRichard OwenIn studying several pieces that look likeLizardWhen bones are fossilized, they are often thought to be the remains of some kind of animal.Prehistoric animalsThe ones that remained were named dinosaurs, meaning 'terrifying lizards.'

Dinosaurs existed 65 million years ago.CretaceousWhen the end comes, they all disappear suddenly, becomingEarth's biodiversity"A mystery in the history of evolution, this mystery remains unsolved to this day. The past life of Earth has been recorded in fossils. In the Mesozoic stratum, many dinosaur fossils have been found. Among them, there are a large number or various shapes of bones. However, in the following Cenozoic stratum, there is no fossil of non-avian dinosaurs at all, leading to the inference that non-avian dinosaurs became extinct at the same time in the Mesozoic era, and now only birds remain. Most scientists recognize the statement that "birds belong to dinosaurs." There are many kinds of dinosaurs, with large differences in body shape and habits. Among them, the large onesFragile Double-Chambered DragonThe size of hummingbirds can vary greatly, with some species possibly exceeding 50 meters, while smaller ones may be less than 10 centimeters. In terms of diet, there are gentle herbivores and aggressive predators.meat eatersThere were also omnivorous dinosaurs that ate both meat and vegetables.

Dinosaur EraIt is so far away from us, and without the help of fossils, we would know nothing about this mysterious species of dinosaurs. Therefore, the research on dinosaurs is also the research on the Dinosaur FossilsThe research of dinosaurs can be roughly divided into two types: skeletal fossils and trace fossils. They are mainly preserved in the formations of the Mesozoic Era.Sedimentary rockThe formation of dinosaur fossils is a complex and long process, involving the death and extinction of dinosaurs, as well as the billions of years of changes on Earth. The discovery and excavation of dinosaur fossils is also not easy. Scientists use various means to find the traces of dinosaur fossils and rely on modern high-tech means to reconstruct and study dinosaurs. Through their work, we have gradually understood the appearance and lifestyle of dinosaurs, and new discoveries and new perspectives from all over the world have repeatedly corrected our original understanding of dinosaurs, making them more close to the truth.

The End of Time

Dinosaurs appeared in the Late Triassic, about 235 million years ago, and became extinct at the end of the Cretaceous, about 65 million years ago, during the Cretaceous-Paleogene extinction event.
