Carboniferous Period The Carboniferous Period was a time period in the Geological Time Scale that came after the Devonian Period and ended at the beginning of the Permian Period. It lasted from 359 to 298 million years ago. The Carboniferous got its name from the large amount of coal deposits that were found during this time scale. In North America, the period is often separated into two, the Mississippian and the Pennsylvanian. During this time period, the environment had a lot of swamps. The lands
different climates and many different species. Because of these changes geologists have broken earths history into different time periods. One such time period was the Pennsylvanian time period. The Pennsylvanian time period is a subdivision of the Carboniferous period. The Pennsylvanian period saw the introduction of many different species that are still present today along with a very different climate and different geographical features than are present today. Before getting into some of the physical
progressive era turned into Earths most catastrophic event. The Permian Period occurred around 298 million years ago. It stretched from the Carboniferous Era to the Triassic. Sir Roderick Murchison in the early 1800’s noticed a differentiation among the overlay of the rock formation in the Ural Mountains in Russia. These rocks differed from the older Carboniferous rocks in Britain, and seemed younger than the Triassic rocks of Europe. Murchison named this differentiation after the prehistoric kingdom
The Permian-Triassic Extinction is a mass extinction that occurred between the Permian and Triassic geologic time periods approximately 250 million years ago; it is the deadliest of all extinctions that have occurred on Earth. 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
Precambrian Era: The Precambrian Era is when the Earth formed. Earth was barley a spec of dust in outer space and as time went by it gathered ice, rock and more dust particles. It eventually formed into a big rock flying around in space. The Earth was extremely hot and so when it rained the rain would evaporate in mid air or immediately after it hit the ground. But even though it evaporated these great rains cooled the Earth eventually building up water in lower areas creating oceans. The Earths
The mass extinction of Marine-life in the Silurian Period opened up endless possibilities and potential for terrestrial life in the next Geologic time period, The Devonian Period. The Devonian Period served as an introduction to the expansion of the first amphibians, sharks, and some of the first plants with roots, leaves, and stomata. Despite such significant advances, the Devonian Period is best known for its diversity and abundance of underwater life. Not only did fish with cartilage begin to
of looking at other sources like books or the Internet. The visit to Cheddar also enabled us to a cross unit task. This was, water, landforms and people, and people work and development. In this coursework I shall include information on Carboniferous Limestone and how it is formed. I shall also give an introduction to Cheddar and the different parts of it such as the Gough's caves and Aladdin's caves and the gorge. Maps will also be included so that you can get an idea of where Cheddar
holds particularly important collections of brachiopods, fish teeth and other fossils from the Carboniferous, sponges from the Cretaceous, and Paleocene plants. The geology collections in Northern Ireland consist of approximately 30,000 fossils, 11,000 minerals and 4,000 rocks. Its major strengths are fossils from the Jurassic and Cretaceous rocks which fringe the Antrim Plateau, fossils from the Carboniferous Limestone of Ireland, and Ice Age faunas.2a Recent finds include fragments of a rare ammonite
assigned to the cooksonia genus and the vascular systems of complex plants. this period was subdivided into four epochs which had stages. (Fischer,Liu, Yip, and Yu, 1998) The next period was the Devonian around 408 - 360 million years ago and the Carboniferous Period, about 359.2 - 299 million years ago and after the second extinction. this was divided in to two subsystems the Pennsylvanian and the Mississippian which were subdivided to stages. (Waggoner, 1996) This was a time of the first appearance
Greater Manchester therefore has a graded profile, with steep mountains and hills to the north-east gradually settling out to low-lying, fertile plains in the south-west. The county’s geology consists mainly of rock from 3 geological periods; the Carboniferous, Permian and Triassic, alongside glacial deposits left over from Ice Ages in the Quaternary period. The oldest rocks seem to be found in the north-east of the county, and the youngest in the south-east. The Permian and Triassic rocks laid down
Precambrian Geologic The Precambrian era is about 90% of the earth’s geologic life. It refers to all geologic time before 600 million years ago. During the Precambrian era, the earth formed along with the oceans and atmosphere. Originally, the earth was in a molten state, but as it cooled down, it developed a hard crust and oceans that developed water vapor to form an atmosphere. About five hundred million years after the earth was formed, small continents started to form. The plate tectonics also
The Permian Period commenced 298.9 million years ago and ended 252.2 million years ago, ranging from the close of the Carboniferous Period and the beginning of Triassic Period. About 250 million years ago, at the end of the Permian period, something killed some 90 percent of the planet's species. The species of animals in the seas survived no more than 5 percent. On land less than a third of the large animal species made it; nearly all the trees died (Hillel J. Hoffman, 2015). Marine life was devastated
Dark matter has been argued about for a long time about whether it helps or not helps the universe. The universe is mostly made up of dark energy at 71.4%, dark matter at 24%, and atoms a 4.6%. These are the statistics made about the composition of the universe. However, these statistics were not always none. Einstein himself said that the universe was static, that the universe was neither contracting or expanding. When the Russian Mathematician, Edwin Powell Hubble, proved him wrong, Einstein said
2. A stromatolite is a fossil of blue green algae, or cyanobacteria. They date back up to 3.5 billion years ago, and made other life possible by transforming earth’s atmosphere to one much more suited for terrestrial life, by creating oxygen gas. 3. Archean life was extremely basic, essentially making it harder for anything to go wrong with it. Life first appeared in an incredibly hostile environment, todays earth is much more hospitable and abundant with all sorts of life. 4. The Paleozoic era
plants to decompose and protect the peat. The last factor consists of the physical circumstances of the area, which include locations of bodies of water and “rates of subsidence or uplift” (Coal 2005). During a particular humid climate of the Carboniferous Period (360 to 286 million years ago), large tropical trees, ferns, and other plants constructed the great amount of areas that make up the coal beds of today (Peat 2005). The best conditions for coal to form are slow, constant subsidence, levees
Global vs. Local Flood “Is Noahic flood local or global?” Many Christians ponder this question and seek to find the answer. There is substantial evidence supporting both claims, so how are Believers suppose to decipher which is true? Let us begin by looking into the claims and evidence of each argument beginning with the global flood. The first evidence for the global flood involves fossils and their location centuries after the flood. Marine animal fossils have been found on mountaintops in every
big family of species that has all evolved from one another. These 3 groups being Crocodilian, Squamata, and Testudines. Reptiles have been around for millions of years. The earliest known reptiles originated 340-335 million years ago during the carboniferous period, having evolved from advanced reptile-like amphibians that became increasingly adapted to life on dry land. Although there are some reptiles who live on land, water or land and water, reptiles come in all different shapes, sizes, color’s
Again, index fossils and relative dating are the proof of the creatures that inhabited the Earth during this period. Even though there was an explosion of marine life, sixty percent of the species became extinct due to climatic changes and glaciation. After the Ordovician period is the Silurian period (440-410mya), which is best known for life on land. Once the climate stabilized, land plants grew near the equator and the evolution of fishes began. The first known freshwater fish, and fish with

The environment here was shallow marine and Carboniferous Limestone was formed. 255mya all continents managed to collide forming one supercontinent, Pangea. At this moment in time Anglesey was located in the Northern hemisphere. During the Jurassic
active flight has evolved four times in nature, and gliding flight has evolved multiple times. The first animals believed to take flight were insects around 410 million years ago. These first flying insects resembled dragonflies, and were from the Carboniferous. Through the adaptation of wings insects were able to grow much larger than modern insects, and to evolve into more than six million unique species. 248 million years ago select reptiles developed the ability to glide, but they never became active
