Climate And Floral Change Over The Last 65 Million

Abstract Throughout Earths history, it has gone finished galore(postnominal) substantial changes which have ultimately determined the dry land to the introduce it is in now. One of these key events occurred during the Cenozoic time halt, near 65 million age past; this change altered the geographics and also the geology of Earth immensely. During this time, the world underwent extreme changes in its worldwide modality experiencing alternating periods of lukewarm and colder climes 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 conspiracyeast Australian region. Introduction The Cenozoic era began well-nigh 65 million years agone and consisted of several study 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(prenominal) flora to line up to its changing environment. The species of plants which were unable to get away with such changes in climate such as temperature and humidity ultimately became much and to a greater extent 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 comparatively humid climate with comparatively high levels of precipitation (Benbow et. al, 1995). As a result of the cold-temperate contacts, 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 very(prenominal) widespread in the surrounding flora and created a placid meso-micro-thermal rainforest. Early to Late Eocene Notably, the warmest period during the Cenozoic period occurred during...If you pauperization to get a skilful essay, order it on our website: Ordercustompaper.com
