Triassic

The Mesozoic Era contains three geologic time periods including the Triassic Period ,from 252 million to 200 million years ago. The Triassic period was named in 1834 by the German geologist Friedrich August Von Alberti (1795-1878). It was originally named the "Trias". It got its name because this period of geologic time is represented by a three-part division of rock types in Germany . It began 252 million years ago, at the close of the Permian Period, and ended 201 million years ago. Jurassic

based on the red color. Additionally, this formation was named by a geologist by the name of Herbert E. Gregory who studied at Yale University. He was the first to name and describe the upper Triassic including the Chinle Formation (figure 9b) (Uncompahgre, 2014). The Chinle was formed in the Upper Triassic from fluvial (relating to rivers and streams), lacustrine (lake), palustrine (wetlands) to eolian (wind) deposits (Dubiel, 2014). This formation is spread across several states such as Nevada

herbivores and their predators” (Marshall). After this discovery, it was then realized that the Triassic food web was not adversely affected by the extinctions in the Permian environment (Marshall). However, in the middle of the Triassic period, it seems that the food web was unstable, causing the same types of mass extinction as occurred before in the Permian time. The unstable food web in the Triassic time raises some questions about why it appeared less stable than the Permian food web and these

rocks. Paleozoic rocks are for the most part hidden in the Park despite being in the Colorado Plateau, which is likely due to both erosion, and it being buried in other various rocks. Next is the deposition of the Moenkopi Formation during the early Triassic time period. When North America was still apart of Pangea, the area that was the Colorado Plateau was located within close range of the Equator. 300-600 feet of sand and mud were accumulated during this time, with marine life being included which

blood-red planktons. The existing plants in that period were cycads, ferns and conifers. The Mesozoic era was about 245 million years ago to 65 years ago, so it almost lasted about 180 years in total. The Mesozoic era is divided into three periods of Triassic, Jurassic and Cretaceous. Mesozoic era means middle animals and it is the era, which the word’s fauna has changed from what is in the Paleozoic era and the most famous organisms of this era are dinosaurs. In the Mesozoic era, the extinction of more

Introduction The Mesozoic Era began around 250 million years ago and ended 65 million years ago. It is divided into three different periods, The Triassic, The Jurassic and The Cretaceous. In the Mesozoic Era Earth was extraordinaly different from what it is now. The climate was humid and tropical, the sea levels were constantly changing and even the shape of the Earth 's continents were different (Benson et al, 2010). The land was dominant by the dinosaurs but the oceans were populated by more rich

The triassic period lasted for 37 million years, from 245 to 208 million years ago. The Triassic started with a generally warm and wet atmosphere . Be that as it may, fossilized sand found in later Triassic strata propose that the general atmosphere was hot and dry, albeit a few zones may have had characterized stormy seasons. Fossils found in Triassic rocks propose this was a time of progress, in which more established types of plants and creatures ceased to exist and new ones started to show up

Shifting from the end of the Permian period 250 million years ago into the next era, the Triassic period occurred between 250 and 199 million years ago and was know for further diversifying life on land. After the Permian period, the Triassic period was largely successful in adapting and evolving, as the world was going through many changes. The land mass known as Pangea began its separation, which would be completed in the Jurassic period. The climate was relatively more severe during this time

From the presentation the 6th mass extinction: 1. Describe what biodiversity is and why biodiversity is so important. Biodiversity is the variety of spices within plants and animals in the environment, it is an indicator of ecosystem health. The importance of biodiversity: Biodiversity provides humans with food and materials (like wood) that benefiting the economy. Biodiversity performs a variety of ecological services: from absorbing chemicals to cleaning water and providing oxygen. Some types

Life on Earth is what makes Earth, Earth. The planet of life almost became lifeless in history that states back more than 200 million years ago, when 96% of life on Earth was wiped out (Bagley, 2014). This was the closer of the Permian-Triassic period. This means that the rest of 4% that survived this tragic event, which is also called the “Great Dying,” makes up, and is what made life today last up until this generation. Before this period, the Earth provided shelter to many plants and
