The Cause of the Dinosaur Extinction

- The Cause of the Dinosaur Extinction The biggest mystery surrounding the dinosaur is how did they die. For over 130 million years dinosaurs ruled the earth. Then 65 million years ago, at the end of the Cretaceous period, they died out. Nobody can really say what actually eliminated the species, although everyone has their very own idea. Asteroid impact, atmospheric changes (hot to cold), catastrophic eruptions and astronomical events (supernovas etc.). Some have ventured that early mammal inhabitation slowly “pushed” the dinosaurs to extinction....   [tags: Papers]

In addition, during the Permian-Triassic extinction the continents of today existed as one supercontinent known as Pangaea. This was the first time in history where continental or land mass exceeded that of the ocean. This was also before dinosaurs of the Triassic period roamed Earth, during this time animals such as the therapsids, and Synapsids such as the Pelycosaurs, insects and amphibians also occupied Earth....   [tags: Pangaea, Perish, CO2]

Estimating Dinosaur Behavior

- Estimating Dinosaur Behavior Dinosaurs are an extinct group of animals that thrived for 165 million years starting 230 million years ago in the Late Triassic period of the Mesozoic Era. Despite being extinct for the past 65 million years and not being able to study them in their true form, scientists have been able to estimate many different behaviors of dinosaurs. This paper will show that the close study and examination of different types of body and trace fossils, along with animal models, can be provided as evidence to estimate different types of behaviors in dinosaurs....   [tags: display, communication, mating behavior]

The Small World Of Dinosaur Learning Experience

- To review the small world of dinosaur learning experience, I acknowledged that play-based learning plays a crucial role in the development of literacy concept for children. Play planning encourages children to practice using language to discuss the play scenario and to make the roles, props, and actions clear to the other players. It is the time when the educators can prompt the use of new vocabulary and encourage children to use the literacy elements that are in the play area. As educators engage with children as they are learning they are able to support, extend and challenge their thinking....   [tags: Knowledge, Learning, Language, Play]

Mass Extinctions On The Earth

- Intro: Sixty-five million years ago, some phenomenon triggered mass extinctions on the lands and in the oceans so profound that they define the geological boundary between the older Mesozoic Era, often called the "Age of Reptiles," and the modern Cenozoic Era, the "Age of Mammals." On a finer scale, the extinctions define the boundary between the Cretaceous (geological symbol, "K"), and Tertiary ("T") periods. This mass extinction is usually referred to as the K-T extinctions....   [tags: essays research papers]

A Brief History of the Extintion of Large Pleistocene Mammals

- Many of the world`s scientists believe we are in the middle of another great extinction event. Such extinctions have happened periodically throughout Earths history of life. Most infamously is the K-T (Cretaceous Tertiary) event, which killed of our beloved dinosaurs. Pacing back in time, there were five known events; one at the Triassic (which may have gave way to the rise of the dinosaurs), another at the end of the Permian that produced a vanishing of species (approx 95%) never equaled until today as some will argue....   [tags: history of the Earth]

The Vulnerability of Islands to Animal Extinction

- Presently, the rate of species extinction is occurring several thousand times faster than has been observed over geologic time. (Purvis, E., & Mace, 2000) Though they represent a minority of all species, island species make up 75% of animal extinctions since the 16 000's. Because of traits inherent to islands, including isolation and small geographic range (Purvis, E., & Mace, 2000), islands are more susceptible to extinction than the continents. This results in a disproportionate ratio of island to continental extinctions....   [tags: Zoology, Conservation]

The Extinction of Pleistocene Mammals

- During the late Pleistocene, a mystery occurred in which large mammals went extinct in North America while they survived in other parts of the world. Scientists studying the late Pleistocene extinction provided a plethora of explanations, including overkill by humans, extraterrestrial events, and climate changes (Faith and Surovell, 2009). However, there was no unified explanation that they all agreed upon. Taking note of this, J. Tyler Faith and Todd A.

`` Near Extinction Fictional Narratives '

- Near extinction fictional narratives are often constructed around a recognizable Western-based three-act structure – an expository opening in which a catastrophe (or an oncoming catastrophe) introduces itself to the main characters, followed by a middle act in which the protagonists must negotiate themselves through a reconfigured social and/or geographic landscape, followed by a climax which the characters are re-identified into the population, now as survivors. By considering this format as a rite de passage (Van Gennep 1909), a concept that examines various social rituals as passage from one state of social being to another, these accounts may also be reconsidered as status changes t...   [tags: Sociology, Gender role, Heteronormativity]
