Climate And Floral Change Over The Last 65 Million

Abstract Throughout Earths history, it has gone through and through galore(postnominal) significant changes which have ultimately driven the world to the asseverate it is in now. One of these key events occurred during the Cenozoic time period, about 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 tempers due to various(a) reasons. Simultaneously, these changes in conditions had profound effects on both the works and zoological science all over the world, in particular, the southeastern 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 co nditions which affected South East Australia vary tremendously and so led some flora to line up to its changing environment. The species of plants which were unable to cope with much(prenominal) changes in climate such as temperature and humidity ultimately became much and more scarce. Palaeocene During the first gear of the Palaeocene era roughly 65.5 million years ago and terminate 55.

8 million years ago (Britannica Online, 2012), Australia was generally subjected to a warm climate and comparatively humid climate with relatively high levels of precipitation (Benbow et. al, 1995). As a result of the cold-temperate surroundings, botany 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 actually widespread in the surrounding flora and created a smooth meso-micro-thermal rainforest. Early to Late Eocene Notably, the warmest period during the Cenozoic period occurred during...If you wish to get a full essay, order it on our website: OrderCustomPaper.com
