Dinosaur Information

Dinosaurs wereMesozoic eraA category from the period (230 million years ago)ReptilesWell-defined limbs, a long tail, and a massive body are characteristic of most dinosaurs. They primarily lived in forests or open areas on the lake shore plains (or coastal plains).

In 1841, British scientistsRichard OwenSeveral pieces that look similar in the researchlizardWhen bone fossils are studied, they are considered to be some kind ofPrehistoric animalsThe remaining one was named Dinosaur, meaning “terrible lizard”.

Dinosaurs existed 65 million years agoCretaceous PeriodAt the end, everything suddenly disappeared, becomingEarth organismsA mystery in the history of evolution, one that remains unsolved to this day. The organisms of Earth in the past are all recorded in fossils. Many dinosaur fossils were discovered in the Mesozoic strata. Among them, a large number of bones with various shapes can be seen. However, in the subsequent Cenozoic strata, no fossils of non-bird dinosaurs are found at all. This suggests that non-bird dinosaurs became extinct together during the Mesozoic era, and today only birds remain. Most scientists agree that “birds belong to dinosaurs.” There are many species of dinosaurs, and their sizes and behaviors vary greatly. Among them, the larger onesFragile Dual-Cavity DragonIt can exceed 50 meters, while small hummingbirds are less than 10 centimeters in size. In terms of diet, there are gentle herbivores and aggressive ones.CarnivoresAlso, omnivorous dinosaurs that ate both meat and plants.

Dinosaur EraSo distant from us, without fossils, we would know nothing about the mysterious species of dinosaurs. Therefore, the study of dinosaurs is also a study ofdinosaur fossilsResearch. Dinosaur fossils can be roughly divided into skeletal fossils and trace fossils, which are mainly preserved from the Mesozoic period.sedimentary rocks<t_IXXYZZ>China. The formation of dinosaur fossils is a complex and long process that involves the death and extinction of dinosaurs, as well as the countless changes on Earth over millions of years. Discovering and excavating them is equally challenging. Scientists use various methods to find clues about dinosaur fossils and employ modern high-tech techniques to reconstruct and study them. Through their work, we gradually understand the appearance and lifestyle of dinosaurs. New discoveries and perspectives from around the world continually refine our original understanding of dinosaurs, bringing them closer to the true facts.</t_IXXYZZ>

Time of Destruction

Dinosaurs appeared in the late Triassic period around 235 million years ago, and went extinct during the end-Cretaceous mass extinction event in the late Cretaceous period around 65 million years ago.
