Cinozoic Era Research Paper

Decent Essays

The Cenozoic era (65mya to present), the current era of Earth, includes three periods, Paleogene period (65-23mya), the Neogene period (23-2.58mya), and the Quaternary period (2.6mya-to present). After, the decline of dinosaurs, mammals took centerstage, and the climate changed drastically. Paleogene period (65-23mya) is the first period of the Cenozoic era, during this period most of the Earth's climate was tropical, and the continents of Earth drifted further apart producing expansive oceans. In addition, invertebrates, fish and reptiles started to evolve into the species we know today. Towards the end of this period mammals, birds, protozoa, and flowering plants experienced a distinguishable evolutionary change. Tertiary fossils are used as evidence proving the existence of the life forms in this period. The second …show more content…

At the end of the last Ice Age smaller mammals replaced large mammals of the Ice Age. It is proven through radio carbon dating that during the end of the last Ice Age, humans migrated their way to what is now England which was in a rapid warming cycle. Again, carbon dating is found by, “The determination of the age or date of organic matter from the relative proportions of the carbon isotopes that it contains.” The events that began in the Cenozoic era have helped to determine what flora and fauna exists on Earth today. Concerning the history of the Earth I am ambiguous to all of the milestones presented based on scientific evidence that are discovered through the use of the law of superposition, index fossils, radioactivity, and the relative age of a rock. These are seemingly sound methods to gain more information regarding the Earth's history. However, I am also partial to the ideology of the bible and cannot yet accept or decline the research I have
