The Latest Saying Of The Extinction Of Dinosaurs
According to world media reports, scientists generally believe that there was a huge celestial body falling on the earth, leading to the extinction of dinosaurs and many other animals. However, the latest research shows that the extinction of dinosaurs is caused by double attacks in the sky and the ground. So what is the specific? The Animatronic Dinosaur manufacturer can pull the science popularization after consulting the information.
The dinosaur era ended in the K-T period or the Cretaceous-Tertiary extinction event 65 million years ago. The extinction caused nearly half of the deaths on the earth. The dinosaurs were completely extinct and the birds survived the disaster. The most common explanation is that the dinosaur extinction was caused by an asteroid or comet hitting the Earth, and the impact left a huge crater called Chicxulub on the Yucatan Peninsula in Mexico.
Another major theory about the extinction of dinosaurs is that a series of large-scale volcanic eruptions dating from 63 million to 67 million years have caused this species to disappear from the earth. India's Deccan trap is the remains of the volcanic eruption, initially covering 580,000 square miles (1.5 million square kilometers), equivalent to twice the size of Texas.
Scientists generally believe that there was a huge celestial body falling on the earth that led to the extinction of dinosaurs. So now we can only see Giant Dinosaur Model in museums or theme parks to understand this monster.
Giant Dinosaur Model
The main focus of the debate over the extinction of dinosaurs is whether the time of each disaster and the extinction of species are later. Previous research has determined the eruption time of the Degan volcano between 300,000 and 500,000 years after the extinction. Recent studies have shown that mass extinction of organisms occurs at one of the largest stages of the Degan volcanic eruption, or that 80% of the volcanic rocks in the Degan area are spewed out at this stage. Gilta Keller, a paleontologist at Princeton University, said: "This is the first time we have been able to directly link the main stages of the Degan group to mass extinction."
Keller and colleagues focused on the study of marine fossils excavated at the Rama Mondari quarry in India. Rajamondri is located near the Bay of Bengal, about 600 miles (1000 km) southeast of the Degan Rocks Center near Mumbai. In particular, they scrutinized the remains of micro-organisms called foraminifera. Keller explained: "Before the mass extinction event, most foraminifera were quite large, colorful, and had multiple cavities." These foraminifera are about 200 to 350 microns long, or about five long. One millimeter or one third millimeter.
These gorgeous color foraminifera can only survive in certain ecological environments. Keller explained: "Once the environment changes, such as the environmental changes caused by the Cretaceous-Tertiary extinction event, this will accelerate their extinction. The resulting foraminifera is extremely small, equivalent to the original twenty First, there is absolutely no gorgeous decoration, and there are only a few cavities.” As a result, these miniature foraminifera can be used as a unique symbol of the beginning of the Cretaceous-Tertiary extinction event. The researchers found that the simple form of foraminifera appeared exactly after the main stage of the Deccan volcanic eruption, which meant that the mass extinction event had just ended and the volcano in the Deccan region began to erupt.
Whether it is a meteorite impact on the earth or a volcanic eruption, it will spray overwhelming dust and other gases into the air, dramatically changing the global climate, causing some creatures to die until they become extinct. The volcanologist Vincent Cortilot, a collaborator of Keller Research and the Institute of Geophysics at the University of Paris, pointed out that their latest research shows that the volcanic material that ejects into the air in the Degan region is caused by climate change. The ruble hits ten times the same material produced.
The above is the latest statement of Animatronic Dinosaur Costume suppliers about the extinction of dinosaurs, hoping to help everyone.
