Climate And Floral Change Over The Last 65 Million

Abstract
Throughout Earths history, it has gone through galore(postnominal) significant changes which have ultimately driven the world to the introduce it is in now. One of these key events occurred during the Cenozoic time period, roughly 65 million years past; this change altered the geography and also the geology of Earth immensely. During this time, the world underwent extreme changes in its orbicular modality experiencing alternating periods of warmer and colder climates due to various reasons. Simultaneously, these changes in conditions had profound effects on both the flora and zoological science all over the world, in particular, the Southeast Australian region.
Introduction
The Cenozoic era began roughly 65 million years agone and consisted of several major periods: the Paleocene, Eocene, Oligocene, Miocene, Pliocene and Pleistocene. As mentioned earlier, throughout the chronological forward motion through these periods, the climate and conditions which affected South East Australia vary tremendously and consequently led some flora to line up to its changing environment. The species of plants which were unable to cope with such changes in climate such as temperature and humidity ultimately became much and more scarce.


Palaeocene
During the beginning of the Palaeocene era roughly 65.5 million years ago and ended 55.



8 million years ago (Britannica Online, 2012), Australia was generally subjected to a warm climate and relatively humid climate with relatively high levels of precipitation (Benbow et. al, 1995). As a result of the cold-temperate surroundings, vegetation during this time consisted mainly of rainforests and swamplands. Gymnosperms, vascular plants which produce vulnerable seeds, and Protaeceae, a family of flowering plants widely distributed in the Southern hemisphere (Australian Government, 2000) were very widespread in the surrounding flora and created a cool meso-micro-thermal rainforest.
Early to Late Eocene
Notably, the warmest period during the Cenozoic period occurred during...If you want to get a full essay, order it on our website: Ordercustompaper.com
