A research team in the German city of Hanover announced that the extinction of dinosaurs 66 million years ago was the result of the fall of a space asteroid on Earth. The research team, which includes German scientists, in this new study, said that the region of southern Deccan, India, has long witnessed massive volcanic activities that could be the cause of the elimination of dinosaurs.
However, the scenario of these volcanoes is not consistent in time with the study published by the journal “Science” specialized in these areas. And nearly half of the volcanic gases absorbed in the Deccan region came in time before the extinction of the dinosaurs, said Andre Bornmann of the German Federal Institute for Geological Sciences and Raw Materials in Hanover.
This geologist was part of the international team that studied fossil nuclei taken from the depths of the seas in the north and south Atlantic and Pacific Oceans, and precisely reached the time period between the Cretaceous and Paleogene periods 66 million years ago, which saw the extinction of up to 75 percent of Animal species.
For this study, scientists used procedures such as referencing scientifically recovered temperature changes, scientific excavations, and models of the carbon cycle. The study said that the result of the asteroid strike on the Earth is still present and is a volcano standing in front of the Mexican Yucatan peninsula, the diameter of its crater is approximately 200 km.
The study said that this event could have triggered a tsunami and released huge amounts of sulfur. American researchers confirmed this hypothesis shortly by measuring the contents of the samples from the aforementioned volcano. Bornemann added that the volcanic movement in the Deccan region is really responsible for the temporary rise in temperature 200 thousand years before the death of all living things, but they did not have long-term effects on the biologist and climate later.

Extinct dinosaurs in world museums
In the movie “Jurassic Park” directed by Stephen Spielberg, the dinosaurs “Spinosaurus” and “Tranosaurus” are confronted in a bloody battle. What happened was entirely inspired by science fiction, because the facts indicate a forty-million-year time gap between the dinosaurs. The skeleton of this dinosaur a few years ago in Morocco The structure in the Berlin Museum of Natural History is only a template for display.

The dinosaur “Spinosaurus” lived a hundred million years ago, and it was a unique type of dinosaur, as it lived in an aquatic environment. He was also able to chew his prey with his strong jaws and devour it to the bone. The bones of this dinosaur were first found in 1912, but the chaos that accompanied World War I led to their disappearance. Nowadays the Museum of Natural History displays the first life-size model of the skeleton of a dinosaur “Spinosaurus”.

Yesterday dinosaur fans can see the dinosaur “Spinosaurus” standing alongside the dinosaur “Tyrannosaurus” known as “T-Rex”. The dinosaur exhibition “Spinosaurus” ends on June 12th. The T-Rex dinosaur exhibition, also known as “Tristan Lotto”, which is the name of the son of one of the owners of the dinosaur, will continue its performances from December in Berlin for a period of three years.

Due to the heavy weight of the skull compared to the length of the T-Rex skeleton, which is 12 meters, it is displayed in a separate showcase at the Berlin Museum of Natural History. 3D printing technology was used to create a replica similar to the original skull and attached to the skeleton. The skull is one and a half meters long and is ninety-eight percent in good condition.

The dinosaur “Spigosaurus” is 40 meters long, 20 meters above the ground and weighs 80 tons. These bones discovered in 2014 in Argentina are considered to be the largest dinosaur ever discovered. And due to the fact that the process of revealing the skeleton is not completely complete, experts in Berlin speculate how large the dinosaur “Stegosaurus” and know its true size.

Unlike dinosaurs at the Berlin Museum of Natural History, dinosaur “spigosaurus” is considered a peaceful creature that relies on its food for plants. Its skeleton, which consists of 300 pieces of bone, is considered the most complete, with a head to tail length of six meters and sixty centimeters, and it is now displayed in the Natural History Museum in London.

The Tyrannosaurus Rex dinosaur is on display at the American Museum of Natural History in New York City. The skeleton bones are characterized by their impressive, healthy condition. The skeleton was discovered by a German oil company that was exploring for oil in Argentina. The region where the skeleton was discovered is located in the “Patagonia” region, in southern Argentina, which is a magnet for biologists and fossils.
