Dinosaur National Monument ensures an expansive store of fossil bones of animals that lived almost 150 million years prior. The fossils enable us to take in more about these intriguing creatures. Dinosaur National Monument is extraordinary in light of the fact that guests can see fossils uncovered on the bluff face of the Douglass Quarry at the recreation center guest focus. This site gives a standout amongst other previews of Jurassic dinosaurs discovered anyplace on the planet. The quarry was…

Strata Essay In the diagram given, fossil "C" is the oldest out of fossil "B" and "A"mane they were all found in sedimentary rock. In between each fossil there were events that occurred that left layers behind, like a volcanic explosion. From this diagram, you can predict the relative ages of each strata and fossil. Before fossil "C", there was volcanic ash, then A layer of sedimentary rock, then more volcanic ash. The volcanic ash shows there were two volcanic irruption's, but they weren't…

Varanus komodoensis more commonly known as the Komodo Dragon is a testament to animal adaptation. Based on fossil records, the Varanidae family of lizards appeared around 100 million years ago, during the Cretaceous period. Then, about 3.8 million years ago, the direct ancestor of the Komodo Dragon first evolved on or near Australia. (Hocknull et al. 2009) It was previously thought that the Komodo Dragon evolved in Indonesia. In 1912, Pieter Antonie Ouwens, a Dutch scientist, was the first…

Sauropoda For my dinosaur, I chose to research the Sauropoda. According to scientists, the Sauropoda was thought to be alive during the late Triassic period, which was roughly 65 million years ago. As a result of scientist’s theories, they believe that the Sauropoda was killed of at some point during the cretaceous period. Sauropoda means,”Lizard footed”. Because scientist have found more and more information about these dinosaurs, they are still coming up with different theories. The…

The paragraph draws a conclusion that the fine lines discovered in a fossil skeleton did not certify that Sinosauropteryx was a feathered dinosaur. Whereas, the lecture rebuts this statement, and manifests that Sinosauropteryx has feathers. To begin with, the paragraph asserts that the fine lines were the fibers decomposed from skin preserved in the fossil instead of functional structures. Contrary to the reading, the lecture refutes that the fine lines are indeed functional structures,…

For approximately 160 million years, the terrestrial environment was dominated by dinosaurs. Dinosaurs arose from fully bipedal ancestors, who is believed to have been a carnivore or omnivore (Langer, Ezcurra, Bittencourt & Novas, 2010). These agile terrestrial archosaurs lived during the Late Permian and Early Triassic and had already developed key changes in the hips and ankles that set the stage for the increase in body size that is seen in dinosaurs (Pough, Janis & Heiser, 2013). This…

Brontosaurus Othniel Charles Marsh discovered and named the Brontosaurus (Greek “thunder lizard”), a four-legged dinosaur in 1879. With at least three known species, this dinosaur lived in the Morrison Formation of present day Western US, during the late Jurassic Period and became extinct by the end of the period. Perhaps one of the most controversially classified dinosaurs, paleontologists have reclassified the Brontosaurus several times since its discovery to an extent that some quarters…

The passage on the body temperatures of the dinosaurs dictate that dinosaurs were endothermic animals. Three reasons are being given for this arguement: existence of dinosaur fossils in polar region, the leg position of the dinosaur and the haversian canals in the bone structure of the dinosaur. The fossils that have been founded in the polar region is being classified as a clear indicator for endothermy in dinosaurs. However, the lecturer confronts this point by highlighting the climate in the…

Introduction For my research paper I was given the West Berkeley Shellmound. The purpose of this final paper is to explore the issues and concepts covered in the course, Anthropology 2 – Introduction to Archaeology, by considering the limitations and potentials of archaeological research. It is in this paper that I will assess the limitations of data, methods, and theory for the past investigation at the West Berkeley Shellmound and use critical evaluations to construct an alternative research…

Did you know that some dinosaurs had wings and feather but they didn’t have any use for flight? According to “Raptors: The Bird-like Dinosaurs of Mesozoic Era” by Bob Strauss, Over 70 million years ago, there was a family of feathered dinosaurs called Raptors. Raptors were feathered Theropods that varied in size from no bigger than a large chicken, to exceeding the height of a full grown man. The time the Raptors lived mainly centered around 65-90 million years ago in the Cretaceous era. A…
