...The Jurassic era is one of the most interesting eras on the Geologic Time Scale, it is home to wide array of organisms, so much so that it is called the “Era Of Dinosaurs”, and is notable for the first birds as well. The Jurassic era falls after the Triassic and before the Cretaceous, they are all part of the Mesozoic Era. It begins after the mass extinction event that ended the Triassic, but the earth would recover as this era showed off the most diverse organisms to that point during the Jurassic era. All organisms resided on the supercontinent of Pangea as it slowly moved toward division throughout the early middle, and late Jurassic Era, and even started to divide. Some places such as the southern half of Alabama were submerged in water including several modern counties. This era last about 55 million years, from about 199.6 to 145.5, and is the middle period of the Mesozoic....

...Since the first dinosaur bone was unearthed and mounted in a museum for the world to view, people have been fascinated by the gigantic ancient beasts that once ruled the world. Soon movies brought the dry dinosaur bones to life, featuring dinosaurs as the biggest villains of the film industry. America’s love affair with lost worlds, super-sized villains, and industry leading special effects, helped to make dinosaurs on the big screens biggest stars. Dinosaur movies have captivated our imagination, haunted our dreams and entertained Americans since the early days of film.

... Name: Emily Ailafo Scanlan Date: 6 November 2017 Professor: Britt Brooks The Jurassic Period of the world was dominated by distinct reptiles otherwise known as dinosaurs. Some of the largest dinosaurs existed during the Jurassic including massive herbivores such as Brachiosaurus. On the other hand, large predators and carnivorous dinosaurs also prowled the land. One of the most common meat-eaters of the Late Jurassic period was the Allosaurus. While Allosaurus was not as deadly or as large as other carnivores, it still proved to be a common and successful dinosaur of its time. The first fossil of Allosaurus was originally described as a “petrified horse hoof”...

...would travel back in time to the time period of 1920s-1980s in the United States of America. Another reason why I would travel back in time would be in the time period of 1776-1820s in the United States of America. Then my final destination would be the Jurassic Age to see the dinosaurs. As you were reading/hearing what I said I hope that you assume that I like U.S.A. history and how dinosaurs were like. I would see a pleather of things in the time period on 1920s-1980s. For instance, I would get tutored by Albert Einstein himself. Also I will also purchase ten pairs of Back to the Future shoes, and then sell them in the present for profit. I will also see what Northern Cambria (Spangler/Barnesboro) was like. Throughout these years that I would travel, I would get myself different types of suits and get a mint-conditioned Johnny Cash Album –the rare one. The next time period would be from 1776 to the 1820s to see what old America was like. For instance, I would look for George Washington to see what he looked like and to hear how he spoke. Next I would see the Declaration of Independence being made and actually be part of their conference for the Declaration of Independence. Also, since I am a coin collector, I would take hundreds of the first coins that were made in the U.S.A. I will also, from a distance with binoculars, watch how the War of 1812 unraveled and took form. Most likely, the final destination for now…, would be the Jurassic Age. During this age I will have to...

...Dinosaurs In Alaska? When you hear a place about Alaska, we think of snow, polar bears, glaciers, and cold weather. When you think of dinosaurs, we think of tropical places and hot climates. You would probably doubt dinosaurs could have ever lived here in Alaska. But about 65 million years ago they not only lived here, they thrived! There are a lot of information about dinosaurs, but what this paper will cover is how dinosaurs directly relate to Alaska. After reading this paper, you will find out how dinosaur research started and how long ago dinosaurs lived in Alaska. Plus find out the type of dinosaurs that lived Alaska, and the type of climate and which parts of Alaska that they lived in. You will also find out what type of evidence they found, if dinosaurs are related to the oil industry, who is still studying dinosaurs, and how this topic is introduced to the public. How it all began Dinosaurs strolled the earth over 245 million years ago. So it would only be fair to go all the way back to the beginning and quickly summarize how it all happened. Earth’s history is categorized into two eras, and then categorized by periods. The two eras are Paleozoic era, and Mesozoic era. Paleozoic era - (560 to 276 million years ago): This is the period where the first fish, corals, shellfish, insects, spiders, and swamp forests appeared. Mesozoic era - (350 to 65 million years ago)We are most interested in this era. This era contained 3 periods: Triassic period, Jurassic...

...The history of reptiles began when the first reptiles evolved from amphibians. Fossils of the first reptiles have been found in deposits from the early Carboniferous period (359-299 mya) and possessed characteristics that made them greatly resemble lizards; they were small in size, had four legs, were vertebrates, and possessed teeth that classified them as insectivores. These reptiles flourished due to the sheer amount of insects available around them, and by the end of the Permian period (299-251 mya) they had become the dominant land vertebrates. The Permian Period ended with the formation of Pangaea. Reptiles were successful in the interior of Pangaea because of the arid climate that they were adapted to; however, the end of the Permian...

...million years ago, dinosaurs began to evolve after the period the Permian extinction. dinosaurs began to develop and grow throughout the Triassic period, and were seen as a great threat to other living creatures around them. However, about 66 million years ago, dinosaurs became extinct near the end of the Cretaceous period due to a huge comet or asteroid that struck the face of the earth. This area, at the time, was under water but is today known as modern day Mexico. Dinosaurs had first began to evolve from a species known as the archosaurs. Archosaurs were Triassic reptiles and were much smaller than the later species of dinosaurs. These Triassic reptiles carried certain features that were much different from the species that they had evolved into. They had a much different posture, almost as if they were “locked in”...

...Name: Tutor: Course: Date: The Allosaurus dinosaur The Allosaurus dinosaur is a member of the dinosaur group called the Theropods.The Theropods were meat eating dinosaurs that walked on their two back legs. The name Allosaurus means ‘different lizard’. The Allosaurus is believed to have lived about 163 to 144 million years ago (Britannica 86).This period is referred to as the late Jurassic period. It had a life span of 25 years. Most of the fossils of the Allosaurus where found in North America, Colorado, Utah, New Mexico, Montana, south Dacota and Wyoming (Britannica 86). The Allosaurus reached up to 39 feet (12 meters) in length, stood about 15 feet (4.5 meters) tall, and weighed up to 2 tones. It had a massive head that measured about 3 feet (1 meter) long with it being supported by a short thick neck together with two horns sticking out of its head. It possessed sharp teeth that were curved and had saw like edges. The Allosaurus had sharp claws on the three toes of each hind foot and long grasping claws on the three toes of each front foot. To cap it all it had along, strong and heavy tail that was mainly used to maintain balance. The Allosaurus is believed to be a meat-eating dinosaur that preyed on the plant eating dinosaurs. Its sharp teeth made it fit for meat eating. Its main pray is believed to be the Stegosaurus dinosaur. The Allosaurus hunted in cooperative packs according to some scientists. By hunting in packs they would bring down very large pray. Although...

...Boom, thod, rawr! Wow, a dinosaur! Well, that what I would have said if I heard those noises. Dinosaurs were the first living organism to walk the earth. Their dynasty lasted for 200 million years and was separated into three different periods: the Triassic, Jurassic, and Cretaceous. The Cretaceous period was the final period of the dinosaurs and to have a better understanding of this period we must look at the climate and the geographical landscape, then we must have knowledge on the many things that lived during this time (dinosaurs and unique sea animals), and finally how the Cretaceous came to an end. The Cretaceous was made up of tropical and subtropical climate throughout the globe. These two types of climates controlled the Earth causing it to have hottest temperatures during the...

...tiles of the floor. Visibly frightened, Lex and Tim tremble as one of the beasts peers its head over the island they cowered behind. Luckily for them, it senses nothing and clicks onward. Then, as if by accident, the raptors massive, muscular tail sweeps across the countertop and sends pots and pans crashing on top of the kids. Lex shrieks as they both dart behind yet another row of counters, but it seems that the raptors take no notice over the crashes and clangs of the pans. It seems they have evaded their predators until Tim flattens himself to the side of cupboard accidentally knocking over a ladle, which seems to stop time on its way to the hard, thunderous ground. Immediately as the utensil makes its deafening ring, both dinosaurs are on the attack: one leaps upon a table as the other makes its way around to the sound of the noise. Lex beckons Tim to follow her to the opposite side, but Tim is frozen in fright. He instantly regrets his decision, though, as one Velociraptor roars as it comes upon the ladle. After their brief inspection of the spoon, they are about to round the corner that would reveal Tim, but Lex manages to catch their attention by banging a ladle of her own against the floor. Now, the...

...T. Rex had a well-developed sense of smell, and its hearing and vision were probably better than average by late Cretaceous standards. One unconventional weapon may have been T. Rex's bad breath; rotting chunks of meat stuck in this teeth could have transmitted fatal bacterial infections to any animal lucky enough to survive an initial bite.As "arms races" go, T. Rex was a hands-down loser this dinosaur's arms were so short and stubby that they would have been nearly useless in a fight. Also, despite what you've seen in movies like Jurassic Park, T.

...Dinosaurs, contrary to what many people think, are not just big lizards. While it is true that the name dinosaur (coined by Sir Richard Owen in 1842) means "terrible lizard" in Greek, dinosaurs are quite a distinct group from lizards. The first dinosaur bones were discovered in 1822 in Sussex, England, by Gideon Mantell. It was a herbivore (plant eating) dinosaur later given the name Iguanodon. Shortly after the Sussex discovery the first carnivorous dinosaur, a Megalosaurus, was found. It is believed that from about 230 million years ago, to 65 million years ago (The Mesozoic Era) dinosaurs were the dominant form of life on Earth. At the end of the Mesozoic, dinosaurs, and many other species of life, went extinct. The cause of this extinction is a mystery. Dinosaurs are considered to be reptiles. Unlike most reptiles dinosaurs all walked with their legs directly below their hips. This is different than a lizard or a crocodile where the top section of the limb is splayed out horizontally from the body and the lower section goes from the "knee" joint straight down to the ground. Because of this lizards and crocodiles move low to the ground and almost appear to be dragging themselves around on their bellies. In contrast, dinosaurs walked in an upright manner (Though a few species, like Triceratops, did retain the lizard-like sprawl on it's front legs as it lumbered about). We can tell dinosaurs walked with their feet under their hips by carefully examining the way their...

...The Cambrian Period is in the Paleozoic Era. The Paleozoic Era was known as the "Age of Marine Life." This "Age of Marine Life" all began with what is called the "Cambrian Explosion." The "Cambrian Explosion" happened roughly 542 million years ago and obviously took place during the Cambrian Period. It was when most of the major groups of marine animals appeared in a relatively short period of time. According to fossil records, Bryozoa, algae, sponge (porfera), Arthropoda (trilobita), Mollusks (plecypoda, gastropoda, cephalopoda), and corals first appeared all in the Cambrian Period. The Ordovician Period followed the Cambrian Period, and this is when some of the first brachiopods appeared, such as clams, snails, and cephalopods. Also, ostracoderms, jawless armored fish, were the earliest vertebrates that appeared in this time period. "Typical Ordovician fish had large bony shields on the head, small, rod-shaped or platelike scales covering the tail, and a slitlike mouth at the anterior end of the animal" (www.ucmp.berkeley.edu). During the Silurian, there was a widespread radiation of crinoids, a continued proliferation and expansion of the brachiopods, and the oldest known fossils of coral reefs. There was also the appearances the first known freshwater fish. And finally, the first record of life on land! Fossil records show a group of fungi on land, and also arachnids and centipedes. According to www.ucmp.berkeley.edu, "Most Silurian plant fossils have...

...In the following I will discuss the atmosphere of the late Cretaceous (end of the dinosaur era) and how it may have contributed to the extinction events that occurred at the end of this era. I will also discuss how scientists determine the composition of ancient atmospheres. The Cretaceous period was from 145 to 65.5 million years ago. You had the early cretaceous epoch and the late cretaceous epoch. Mass extinction happened and comprised of 80-90% of marine species and 85% of land species, including the dinosaurs. About half of all life-forms died out, including the dinosaurs, pterosaurs, plesiosaurs, ammonites, and many families of fish, snails, sponges, sea urchins (Benton, 2003). The meteor impact inhibited photosynthesis. The atmosphere was filled with dust cloud which blocked the sunlight for at least a year. Sulfuric acid was injected into the stratosphere. This also created a reduction in sunlight to the Earth by 20%. Because the atmosphere was filled with this acid and dust clouds the plant life and small creatures would die off. It takes at least 10 years for the atmosphere to clear itself of these pollutants. An impact such as this can also produce acid rain. There are many animals that can not handle acid rain. Therefore, this would also play a part in extinction of species. (www.tulane.edu). When it comes to how scientists determine the composition of ancient atmospheres, I found the following; “Ages of ice samples found on the Earth cover a span approaching...
