Dinosaurs Essay

Dinosaurs lived over 65 million years ago, part of their existence was in pangea which broke up 200 million years ago. There were three periods. The triassic period, the jurassic period, and the cretaceous period. The triassic period was the first period of the mesozoic era and happened between 251 and 199 million years ago. The triassic period was when other animals started to form that could walk on land and not in water. The jurassic period was the second period of the mesozoic era and happened

to as the K-T (Cretaceous Tertiary) extinction but is now called the Cretaceous Paleogene (K-Pg) event by many researchers. So from this information a question has been derived, How effectively does the asteroid theory explain the extinction of dinosaurs compared to other theories? A wide variety of extinction theories have been suggested and some of the following examples have been evidentially thought wrong by many. Some examples of the extinction theories are the toxic volcanic gasses and dust

There have been many theories to explain the dinosaur extinction. However, Walter Alvarez and colleagues had discovered the evidence for dinosaur extinction. They found the rocks laid down precisely at the K-T boundary contain extraordinary amounts of the metal iridium. And those materials of the rocks would not normally found on Earth’s surface. Then, they discovered those rocks were asteroids. Scientist discovered the K-T impact crater was deeply buried under in Yucatan peninsula of Mexico. The

On account of "The Great Dinosaur Rush," a joined 136 new species were included. The fervor created open enthusiasm for the old mammoths with the unpronounceable names being found on their boondocks. Swamp's notice that a few dinosaurs looked like winged animals has been vindicated and Como Bluff would stay among the wealthiest American bone beds worked. While it would survive,

scientific questions on the internet. There are many different unsolved scientific questions including dinosaur extinction, black hole and many other questions. Then I use Google Scholar search the related information about these questions and I found that there are more information about the extinction of dinosaurs. Therefore, I decided to wrote a scientific research report on extinction of dinosaurs. For this assignment, I need to summarize the different possible explanations given by the scientists

And while there are tons and tons of fascinating species in the world, there was always one topic in particular that stood out to all of us- dinosaurs. Whether it was just the sheer concept of another species living on the earth before we were even alive, or the tales we were told about their incredible strength and size, we were transfixed by dinosaurs, specifically their disappearance. One thing that never quite made sense was how such an exceedingly powerful group of animals, that lived in

The mass extinction of the Dinosaurs has been a subject of interest and dispute for many scientists over the years. There are many different theories on what happened to them: did some planetary destruction happen, did they die out, were they wiped out, or was it the cause of something not of this planet. This question and this need to solve the mysteries of the world has continued to draw scientists in for the never-ending search for the answer. Scientists have worked tirelessly in an attempt

Dinosaurs (Gk. deinos, meaning "terrible," "potent," or "fearfully great") are a diverse group of animals belonging to the clade Dinosauria. The taxon Dinosauria was named in 1842 by paleontologist Sir Richard Owen. They first appeared during the Triassic period and most of them became extinct after the Cretaceous–Paleogene extinction event (end of Mesozoic Era). There are several opinions about the life-style, metabolism and temperature regulation of dinosaurs. Among them, there is a huge controversy

Outline The Dinosaur Extinction: • Introduction to the K-T event. • Theories of extinction. • Assumptions of extinction: 1. Due to climate change. 2. Due to small mammals that ate dinosaur eggs. 3. Due to dinosaurs’ bodies that are too big to be worked by their little brains. 4. Due to starvation. 5. Due to environmental change. 6. Due to Supernova that showered the earth in radiation. 7. Due to iridium-enriched mud. • Extinction- Still a theory. The K-T event, or the Cretaceous-Tertiary
