Cold and Darkness Following Earth-Asteroid Collision Contributes Mass Extinction of Dinosaur

The cosmos is undoubtedly the strangest concept, and most parts and factors of the world are still poorly understood by the scientists. However, among all, two most mysterious concepts are the extinction of dinosaur from earth and volcanoes from the Red Planet. While previously, both events are believed to be completely secluded from each other, a new study has found an unlikely and unanticipated link between Martian volcanoes and earth’s largest animal – Dinosaur.

As suggested by the new survey, the final volcanic activity on Mars came to an end nearly 50 million years ago – approximately the same time when a multitude plant and animal species on Earth, including dinosaurs, wiped out from the planet. The study, carried out by research team from NASA’s Goddard Space Flight Centre in Greenbelt, Maryland has revealed that the giant Martian Volcano – Arsia Mons blasted off one new lava stream at its peak to every 1 to 3 million years throughout the concluding peak of commotion and there, the last volcanic activity ceased nearly 50 million years back – an era which is pretty same to the period when Earth’s Cretaceous-Paleogene went extinct from the planet.

The research team has published their findings in the journal Earth and Planetary Science Letters, at the Lunar and Planetary Science Conference, going on in The Woodlands, Texas, on Monday. As highlighted by the paper, the peak activity for the Martian volcanic field at the height of Arsia Mons was most likely took place about 150 million years ago – the same of the late Jurassic period on Earth, and later, died out nearly the same time as the Earth’s dinosaurs went extinct. To those unaware, Arsia Mons is the southernmost of Tharsis Montes Volcano, consisting of three volcanos, located on the Tharsis bulge close to the equator of the Red Planet.

According to Jacob Richardson, a post-doctoral researcher at NASA’s Goddard Space Flight Center in Greenbelt, Maryland and the lead author of the study, “It’s promising that the last one or two volcanic vent on Mars might have been operational in the last 50 million years, which, in  geological terms, is very topical.”

For the study, researchers, led by Richardson mapped the edge of lava flows, exploding out of each of the 29 volcanic vents and concluded their layering or stratigraphy of the flows. By using a high-end method called crater counting – the technique of measuring the number of lava craters at least 100 meters or 330 feet in diameter – the researchers also succeeded in measuring the ages of the lava flows.
