Climate And Floral Change Over The Last 65 Million

Abstract Throughout Earths history, it has gone done galore(postnominal) significant changes which have ultimately driven the world to the install it is in now. One of these key events occurred during the Cenozoic time period, nearly 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 humors due to confused reasons. Simultaneously, these changes in conditions had profound effects on both the phytology and zoological science all over the world, in particular, the south-east 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 af fected South East Australia vary tremendously and accordingly led some flora to line up to its ever-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 counterbalance of the Palaeocene era roughly 65.5 million years ago and cease 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, flora 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(prenominal) widespread in the surrounding flora and created a collected meso-micro-thermal ra inforest. Early to Late Eocene Notably, t! he warmest period during the Cenozoic period occurred during...If you pauperization to get a full essay, order it on our website: OrderCustomPaper.com
