Deccan Traps

Dinosaurs, a dominating specie living in the Earth long time ago, extinct mysteriously. Paleontologists and scientists have established a variety of possible theories to explain. However, all these theories are still debatable.There are four main possible explanations: Asteroid Impact, Volcano Eruption, Falling Tide and Asteroid Impact theory was established by Luis Alvarez in 1980.Many plants and animals were disappeared abruptly from the fossil record as one moves from layers of rocks…

Over time there have been many theories as to how the dinosaurs became extinct, some of these include terrestrial stresses (such as lower sea level or global temperature) and radiation (Pasichnyk, 2011), but the 2 theories that have become the most widely accepted as they have the most amount of supporting evidence are the Impact Theory (otherwise known as the Alvarez Hypothesis (Smith, 2005)) and the Volcanic Theory (Pasichnyk, 2011). The Impact Theory states that millions of years ago a comet…

The word volcano typically brings to mind a mountain with fire spewing forth from the summit. Therefore, a “supervolcano” would be a massive fire breathing mountain but, this is not the case. Most of Yellowstone National Park and some of the surrounding area is a “supervolcano”.While some of the largest volcanic eruptions have come from Yellowstone, it is not the only place these “mega-eruptions” have occurred There have been “mega-eruptions” in Indonesia, Chile, New Zealand, Argentina, Japan…

to five hundred thousand years (Benton 1). They were not the average cone shaped volcanoes we know today, instead they are huge rifts in the Earth’s crust (Benton 2). There is much evidence of the Deccan Traps in India took place around the same time as the dinosaur extinction. The Deccan Traps erupted on a huge scale, which could create a huge impact on the atmosphere and climate. This theory is the main alternative to the meteorite impact and can explain many of the observations…

DARSHAN GANGANNA RAVINDRA Abstract— About Sixty-five million years ago, one of last non-avian reptile species called dinosaurs vanished from the earth. The extinction of this huge animal is a never-ending topic of interest, the mass extension of dinosaurs occurred over a very short geological period. Keywords— Non-Avian Dinosaurs, Mass extinction, Dinosaurs extinction theories; Asteroid impact; Volcanism; I. INTRODUCTION Dinosaurs are the certain group of reptiles which influenced and ruled…

Foxes belong to genus vulpes, the most widely distributed carnivores, found across the earth apart from Antarctica. Three species of foxes occurs in the different habitats of Indian sub-continent. Indian fox (Vulpes bengalensis) found throughout the Deccan peninsula, arid and semi-arid bio-geographic region of India, Tibetan fox (Vulpes ferrilata) found in Tibetan plateau of north India and the Red fox (Vulpes vulpes) distributed from hot desert of Rajasthan and Gujarat to cold desert of…

The K-T or the Cretaceous-Tertiary extinction, was a mass extinction over unknown origin that took out an estimated 60-75 percent of all the species on earth 66 million years ago, most famously the dinosaurs. It was the end of the Cretaceous period and the Mesozoic Era and created the beginning of the Cenozoic Era that is still happening today. Geologically speaking this extinction happened in a very short amount of time. Although the most well known species to go extincted during this time was…
