Triassic Essays

Planet Earth has experience four eras that include eleven periods and six mass extinctions throughout evolution. The Evolving Planet exhibit at the Field Museum in Chicago, IL describes the evolution of Earth in great detail. The evolution of Earth starts in the Precambrian period and continues to the Cenozoic era, which is still continuing today. Evolution is the idea that living species are descendants of ancestral species that existed from earlier forms of life. All the organisms, rocks, or other

The movie Jurassic Park became an international sensation when it was released in 1993. It changed the cinematic art of storytelling. It was widely recognized as a high watermark in computer graphics (Timeline, 2015). The reason for these accolades was the extensive computer-generated imagery (CGI) that was used throughout the movie. Before Jurassic Park, CGI was used but not to this extreme that director Steven Spielberg demanded. • 1985: Young Sherlock Holmes - Stain Glass Man, first completely

Georgios Kepertis Earth 102-6: Death of the Dinosaurs Paper 4: Permian-Triassic Extinction 12-7-2015 The Permian-Triassic Extinction Event: When Life on Earth Almost Ended An event that marked a great transition, an event so overwhelming that most creatures on Earth could not handle it; its power so immense that even plants and insects were almost eradicated from the face our planet. If it were to happen today, humans would most certainly be defenseless against the brute forces of nature, and even

Permian to Jurassic (periodic aridity alternating with glacial periods). *Since mammal-like reptiles were abundant in Permian and in early Triassic period, they must have originated in late Permian or early

The Mesozoic era is sometimes called the age of reptiles. Mesozoic means “middle animals”, and dinosaurs were conceivably the most typical organisms in the Mesozoic. The Mesozoic is sectioned into three periods: Triassic, Jurassic, and Cretaceous. The dinosaurs had evolved in the Triassic period, however, they were not very diverse until the Jurassic. The world’s life forms were very different during this era than either before or after. The Mesozoic era extends

This essay you will earn important facts, whether the number of creatures have increased over time. I will be telling you why their number of creatures have increased or if they have not increased. Has the number of creatures on Earth increased or decreased over time.The reason creatures has increased over time is because creatures has multiplied over the time. A lot of creatures decreased when the mass extinction happened, wiping out all the dinosaurs. This topic is very important because some

Introduction Dinosaur is the name given to prehistoric that lived on the earth for about 160 million years. Although dinosaurs were not lizards, the word dinosaur comes from the term Dinosauria, which means terrible lizards. Most dinosaurs were not very terrible either. These animals have been extinct for over 65 million years, but they have fascinated people for the last two centuries. Dinosaurs came to Existence for us Dinosaurs were the first creatures but not the first one to be known. Before

The Sadlerochit Formation is Triassic-aged, and it consists of 300 to 600 feet of sandstone and conglomerate (Van Poolen, 1974). The Shublik Formation is also of a Triassic age and is home to many different rock types including mainly fine grained rocks, organic rich sandstones alongside muddy sandstones, mudstone, silty limestone and finally limestone

Cenozoic The Quaternary (Pleistocene to Recent) The Quaternary period was shaped by some many events. However, the Ear was characterized by interglacial arrangements. Three periods marked the Cenozoic Era; Paleogene, Quaternary, and Neogene. However, the Cenozoic era was characterized by climatic changes. This accounts for the rich agricultural deposits in Ohio. As a result, the land is adequate for landfill exploration. Consequently, Ohio soil contains huge amounts of fossils, silt, clay sand, and

aquatic and terrestrial) all around the world are involved (Benton, 2011). There have five major extinction events in the last 600 million years ago, the Late Ordovician, Late Devonian, Late Permian, Late Triassic and end-Cretaceous (K–T), respectively in that order (Twitchett, 2006). The Permian-Triassic mass extinction happened in between the Palaeozoic and Mesozoic eras, about 251 million years ago (Jablonski, 1995). This mass extinction was the most devastating by a big margin, this claimed 95% of

Mass Extinction. Source: https://worldatlas.com Mass extinction has impacted our earth's evolution tremendously. From as far back as 500 million years ago during the Cambrian period, to as close to us now 65 million years ago during the Cretaceous-Tertiary extinction event, and all 3 events in between have affected the animals and plants surrounding our planet gigantically. Mass extinction is when there is a rapid decrease of animals and plant species on earth due to the earth's natural disasters

and others believe dinosaurs were much like mammals and others birds, warm blooded. Dinosaurs are creatures that lived on Earth around 251 million years ago. Dinosaurs lived in the Mesozoic Era. This era contained three separate subsections: the Triassic Era, the Jurassic Era, and the Cretaceous. When the Mesozoic Era ended, most or a majority of the dinosaurs were extinct due to a catastrophic event that is still unknown to us today. Dinosaurs walked in an upright position, some dinosaurs used two

was the Devonian which was 370 millions ago with an unknown cause, also affected marine organisms, and depleted more than 20% of families. Later on, the permo-Triassic event occurred 250 million years ago with a possible volcanic cause, and destroyed more than 50% of families, and 80-95% of species. The next event was called the End-Triassic event 202 million years ago and killed 20% of families and 50% of genera. The fifth event was the Cretaceous-Tertiary 65 million years ago, which was caused by

These predators will eat fish, dolphins, turtles, birds, and other sharks. Bull sharks have a specific technique when they stalk. It is called the bump and bite method, and begins with the shark bumping its prey to disorientate and/or kill. They will then impale its lower jaw into its target, and then swing its head side-to-side with its upper jaw to take tissue from its victim(sharks.org). Sometimes, the sharks will hunt in groups. Bull sharks are territorial and is likely the cause for human attacks

Turtles have undergone an interesting history as they evolved from their Eunotosaurus ancestors. Turtles are very good at protecting themselves from predators. Their ancestors go back to as far as 220 million years ago. The turtles hard shell preserve very well which makes their remains very hard to distinguish. I hope you enjoy my turtle evolution research essay. Turtles are reptiles of the order testudines. They have a bony or cartilage hard shell that is used as a shield for protection against

haikouichthys, swam. After this came the Devonian period which was 416 million years ago. The cephalaspis swam in freshwater and evolved so it could swim in water and walk on land. Two million year later, 2.5 million years ago, was the very well known Triassic period. This is when the earliest dinosaurs roamed the Earth. This is also when the first mammals were being born and evolving. Meanwhile tectonic plates were pushing land masses away from each other and split up Pangea and brings us into the Jurassic

following discussion, I have tried to brush against some of them through counter- arguments. ECTOTHERMY OR ENDOTHERMY? Before taking, any side of the discussion one has to keep in mind that the dinosaurs existed in a world very different from ours. The Triassic period was hot and dry, much in contrast to the Jurassic and Cretaceous period, which was hot, humid and balmy with rainforest-like characteristics prevailing, even the mountain peaks are said to be hot. Many scientists hold this as an argument for

Around 500-600 million years ago a large continent formed by the merging of numerous continents, it was known as Pangaea. The forceful movement of the tectonic plates resulted in Pangaea being split into two smaller land masses. These two smaller land masses were identified as Gondwana and Laurasia. The splitting of Gondwana and Laurasia occurred around 230-280 million years ago. Gondwana or ‘Gondwanaland’ was a primeval supercontinent and was once the southern land mass of Pangaea. Gondwana consisted

drift. Our continents shifted over time and moved over the surface of the Earth over millions of years to what our continents look like today, as seen in Figure 1. (“Causes of Climate Change”, Edgar). Figure 1: Continental Drift At the Permian and Triassic eras, we had ‘supercontinents’. Continental drift makes the Earth’s climate change in many ways, ocean currents being one of them. When a continent is close to a large body of water, the water averages the temperature and administers more moisture

A ‘living fossil’ has been determined as ‘an organism that has remained essentially unchanged from earlier geological times and who’s close relatives are usually extinct’ (Merriam-Webster, 1859). This is suggesting that the Duck-billed Platypus, more commonly known as the Platypus, would still be in its primitive form and have similar characteristics to it ancestors. Anyone looking at the Platypus can identify its abnormalities as it is so distinctively unique in the animal kingdom. Its name on its
