Transitional fossil

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…

tongue twister is about the fossil collector Mary Anning. Mary became well known for the discovery of new species of fossil and contributions to the field of planetology . Anning would sell her fossils down by the sea shore to collectors and scientists, as way to make a living . She was not fully recognized during her lifetime for her work because of her low social class and gender. Anning played a role in further understanding natural science (geology) and popularized fossils and their value to…

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…

tools, especially where calcareous fossils are absent or poorly preserved. While diatoms were common both in marine and non-marine paleoenvironment, diatom-based biostratigraphy is widely used in the marine stratigraphic record. Multiple Deep Sea Drilling Projects (DSDPs) made the core samples available from Antarctic, Equatorial Pacific, and High Latitude North Pacific region. The earliest known fossil diatoms are from Lower Cretaceous in age, although fossil record is limited. Diatoms might…

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…

evolutionary process to natural and sexual selection alone. They might have thought there were still some weak points in his theory that made it incomplete, and that natural selection as it was, would not account for the animal diversity discovered in fossils…

aspects. Because of this, Badlands national park has been considered the birthplace of vertebrate paleontology. (nature.nps.gov) Paleontology, which is the study of ancient life, focuses on, but is not exclusively to, the study of fossils. (US parks) Despite this, fossils are the primary sources that scientists use to analyze…

natural history museum is located at the Fort Hays State University, Kansas in the United States (US). Its exhibits are permanent on the walls; they includes fossils collected mostly in the western US and all over Kansas. The museum also has exhibits of minerals and videos that explain the museum history; and its famous ‘fish within a fish’ fossil collection history included. 2 Exposure to Formaldehyde Formaldehyde (FA) is a gas that is flammable, colourless and has a pungent noticeable odour.…

1. Short summary of the history At 145 ± 4 to 66 million years (Ma) ago, Cretaceous period was the last period of the Mesozoic Era, right after Jurassic period and followed by the Paleogene period of the Cenozoic Era (International Commission Chart, 2014). 'Creta' in Latin means chalk and this is due to the large amount of calcium carbonate deposited by shells of marine animals thus resulting in large quantities of chalk (American Geological Institute, 1972). The shifting of continents as the…

Recently, scientists have discovered fossils of an extinct species of turtles that particularly have snouts as noses, similar to a pig. However, because of its snout, it was named Golden's bacon turtle, or Arvinachelys golden. Usually, turtles have one nasal passage in their skulls because of how fleshy their nostrils are. Arvinachelys golden was found by a team from Natural History Museum of Utah and discovered the fossil at the Grand Staircase-Escalante National Monument. In addition, this…
