During recent studies, scientists have discovered prevailing evidence which support the idea that a major meteorite impact may not have been the sole cause of the mass extinction involving the dinosaurs 66 million years ago. Researchers have discovered an array of huge volcanic eruptions in india 66 million years ago which released large amounts of gases into the atmosphere, which drastically altered the climate. This new theory does not in fact eliminate the theory of a massive meteorite…

What’s the Right Theory About the Dinosaurs? In many theories about the dinosaurs disappearing many say meteors are the reason, is that true? The many theories about dinosaurs disappearing is a huge meteor or asteroid,climate change, volcanic eruptions, lava,and fractured crystals. At the same time there are over 40 theories of why the dinosaurs disappeared, but I only listed the most important ones that were mentioned the most. The biggest theory of all of them is the Asteroid , people think…

The extinction of the dinosaurs is one of the most well-known mysteries in our great world, the Earth has its history in the layers, these layers can tell us when, where, and how something happened, the K-T boundary is no exception. These large slabs of Earth can show us the past, millions of years of history, to the beginning. What scientists around the world are trying to figure out, is why the dinosaurs died out, there are many different and unique theories about the K-T extinction. Some…

In her book The Sixth Extinction, Elizabeth Kolbert writes that there have been five mass extinctions in the history of planet earth. She asserts that currently the earth is on the precipice of a sixth mass extinction. In contrast with the previous five, according to Kolbert this sixth extinction is almost entirely caused by humans and our exploitation of the earth. In each of the book’s thirteen chapters, Kolbert highlights a particular species that is now extinct and analyzes the causes and…

Stage 1: What caused the Chicxulub Impactor to enter the Earth’s atmosphere and hit Earth (2) About 65 million years ago an asteroid that is roughly 10 kilometres across, hit Earth on the coast of the Yucatán Peninsula in Mexico. It caused a huge explosion and left a crater that is about 185 kilometres across. This asteroid impact is commonly known to be the reason for the extinction of three quarters of the dinosaurs. (4) The asteroid soared through the sky at more than 40 times the speed of…

This article is intended to discuss the causes that led to the death of the dinosaurs. It mainly exposes the two alternative hypotheses that might have caused this mass extinction by explaining the main reasoning behind each of these premises. The author exposes the points of views of different scientists and geologists in regards to the death of the dinosaurs, which- somehow- remains one of the most heated and contested “battles in science”. Particularly, the paper explains the stance of one…

The Cretaceous-Paleogene Boundary, (K-Pg) boundary, and the associated Dinosaur Extinc-tion theories have many precedents and most could be viewed scientifically from certain and known historical accounts. These hypotheses, some more believable than others, can serve a purpose to study current life and potential trends for future evolutionary traits. Evaluating certain aspects of the theory’s within this research, the main focus will be not be on the factual cause of the extinction, but rather…

near the equator like now. The Cenozoic Era is divided into two periods, the Paleogene and Neogene which are divided into epochs. The Cenozoic has seen the extinction of the non-avian dinosaurs and the rise of mankind. It is marked by the Cretaceous-Tertiary extinction event at the end of the Cretaceous period and the end of the Mesozoic Era, and in the later cenozoic age animals were on the brink of extinction because it was getting too warm, and early humankind were already causing the animals…

The Permian Period The Permian Period is the last one, after the Carboniferous Period, of the Paleozoic Era lasting for about 46 to 47 million years from 299-252 million years ago (mya) (Smith 2011). One major feature of this period is the formation of the supercontinent, Pangaea which affected the environment and the climate as well which gave rise to new species. Another distinct feature is the greatest mass extinction event which killed around 54% of all marine families and most of the…

THEIR ARE MANY MANY THEORIES ON WHY THE DINOSAURS BECAME EXTINCT THE CAUSE OF THIS MASS EXTINCTION VARIES WIDELY. Some of those theories are that Years ago an asteroid crashed onto Earth’s surface. Mountains formed within minutes. In America, a tsunami hit covering plants and animals, under piles of rubble. Debrie was scattered, The planet was broken down and it stayed that way for years. But the most clear explanation to why the dinosaurs rapidly died out with the Mose scientific evedence is…
