The dinosaurs lived on earth for about 165 million years before an asteroid lead to their Extinction (Weems, Robert). Over the years, several theories have been made regarding the extinction of the dinosaurs. The first theory is that the dinosaurs died from global plagues or a supernova. The second theory is that the dinosaurs died from an asteroid hitting the earth.This paper will explain why the second theory is the correct theory. While some experts believe the dinosaurs became extinct due to
The Physiology of Dinosaurs, especially the Thermoregulation, has been historically very controversial subject. Many scientists have done various types of research on this matter and put forward many conclusions. Their views can be categorized into 3 main classes:1.Dinosaurs were Endothermic or Warm Blooded,i.e.they maintain their body at a metabolically favourable temperature by using the heat produced by the internal body functions.2.They were Ectothermic or Cold Blooded ,i.e. they regulate their
Dinosaurs, once lost by time. Gone forever, though a certain movie thought otherwise, and while we can’t do what the Jurassic Park and Jurassic World movies did, we can do the next best thing. Meet Jack Horner, a paleontologist and the best one yet. Not only because he discovered that dinosaurs cared about their young but because he, along with a few others, are working at reverse evolution. They are on their way to creating a real dinosaur, but let’s not get ahead of ourselves and let’s start from
This article is about a group of carnivorous dinosaurs with abrasive, jagged teeth that eventually transformed into beaks. Over millions of years later these bloodthirsty dinosaurs evolved into today’s vibrant, feathered birds. These birds instead have teeth along with beaks, rather than saw-like teeth alone. Yet, how the transformation occurred is still a mystery. However, the Proceedings of the National Academy of Sciences issued a study that provides a theory to the evolutionary mechanism behind
BIOL2110- Vertebrate Zoology Word count: 1056 Dinosaur extinction: An analysis of events and theories that possibly led to the dinosaurs' demise. Ever since the history of Earth has been studied using fossil records, extinctions have always been the object of fascination and interest, particularly the mass extinctions that occurred throughout Earth's history. A mass extinction can be caused by disruptive global environmental changes, where large numbers of species have become extinct (Urry
Since the 1980s the most popular theory for why dinosaurs became extinct was because of a meteor, but many people are skeptical of whether or not the meteor was the only factor in the extinction of the dinosaurs. In Stephen Brusatte’s “What Killed the Dinosaurs,” Dr. Brusatte talks about how the mystery of the extinction of the dinosaurs was a hug influence on his life and caused him to become what he is today. As a teenager Brusatte had a chance to talk to Walter Alvarez, the man who proposed the
ago, long before there were any people, there were dinosaurs. Dinosaurs were reptiles that lived on Earth from about 225 to 65 million years ago. There were many different sizes and shapes of dinosaurs. Some were meat-eaters and some were plant-eaters. Some dinosaurs were very big and some were much smaller. {draw:frame} A fossil is the remains or trace of something that was once alive, but is now long-gone and dead. We know that dinosaurs existed because of their fossil remains, mostly bones
Dinosaurs: Destroyed by an Asteroid After the extinction of dinosaurs, intelligent scientists have come together to study the devastating event. The debate surrounding the death of the dinosaurs has intensified due to many recent theories. Some people believed that an extremely devastating ice age froze the dinosaurs across the world and brought massive extinction. Others believe that a volcanic eruption occurred due to climate change and natural disasters, while some say aliens abducted the dinosaurs
A new dinosaur species was uncovered from within the largest fossil collection at Wits University's Evolutionary Studies Institute. The dinosaur had been hiding for over 80 years in the fossil collection until a PhD student and a professor happened upon the bones. Finding a New Dinosaur Among Old Bones When PhD student Emil Krupandan and Dr. Alejandro Otero visited the Evolutionary Studies Institute (http://www.wits.ac.za/esi/17918/evolutionary_studies_institute.html) to study a collection, they
65 million years ago, dinosaurs ruled the planet. These fascinating animals were the largest, strongest creatures to ever walk the face of the earth, yet, they met a fate that would change the world forever. All that is left are the fossilized remains of these captivating creatures. Their fossils, along with the layers of our Earth’s rock and sediment, tell a story of how they lived and how they died. However, there is still an ongoing debate in the world of science of exactly what catastrophe
