Study Finds Comet That Originated From Oort Cloud Hit Earth 66 Million Years Ago Killed Dinosaurs

The extinction of dinosaurs is a mystery for the world. It is one of the hotly debated topics worldwide. Several theories have cropped up on the subject, but a concrete conclusion is awaited. A new study has now suggested that a comet be blamed for the animal’s extinction. Several past theories said that a huge object had hit the Earth and its devastating impact killed dinosaurs. It is believed that the last dinosaurs died 65 million years ago. It was unclear what the object was. Some experts believed that the object was a comet while some argue that it was an asteroid. The object had struck Earth nearly 66 million years ago. It was also unclear from where it originated.

The new theory said that the object was actually a comet. It originated from the Oort cloud. Oort cloud is a Trans-Neptunian region. It lies at the edge of the solar system. The object was an icy sphere of debris. The study said that Oort cloud could be behind the crash. Its impact triggered the mass extinction of dinosaurs. It ended almost three-quarters of the plant on Earth and animal species. Researchers said that they used statistical analysis and gravitational simulations to make the calculations. They said that comets that originated from the Oort cloud could have bumped off-course due to the gravitational field by Jupiter.

According to studies, Dinosaurs are a diverse group of reptiles. They first appeared during the Triassic period. These reptiles are the subject of active research in today’s era. A past study said that a comet reignited massive volcanic eruptions that contributed to the extinction of dinosaurs by the time Cretaceous period ended. Notably, it was in the early 19th century when the first dinosaur fossils were recognized. The name dinosaur was coined in the 1840s. The fossil skeletons are major attractions since then at all museums across the world. In another related development, paleontologists have claimed to discover new species of meat-eating dinosaurs in the United States.
