recognizably modern rainforests,” (as cited by New World Encyclopedia, 2008). “With no large grazing dinosaurs to thin them, Paleocene forests were probably denser than those of the Cretaceous” (New World Encyclopedia, 2008). The beginning of the Eocene Epoch was a period of continued global warmth and widespread rainforests continued to favor mammals that fed on plants and insects, including the Adapids and Omomyids. Research done by Gingerich (1980) indicates that Adapids exhibited sexual dimorphism

Malea Neese 5969-0906 February 25, 2015 Primate Evolution Midterm Short answer questions 1. The Paleocene-Eocene Thermal Maximum was a period of time around the Paleocene-Eocene boundary during which the Earth experienced a significant rise in temperature. As we discussed in class January 27-February 3, the PETM period conveniently coincides with primate evolution and dispersal worldwide. This period of thermal increase is important to primate evolution because this rise in temperature worldwide

Climate change is approaching levels of Paleocene-Eocene Thermal Maximum about 55.9 million years ago, when a large natural release of CO2 occurred. This paper looks at the difference between this period and anthropogenic CO2 release happening now over a much shorter period of time. The first portion of this article discusses the similarities and differences between the PETM period and the current rapid release CO2 due to anthropogenic contributions. The lasting effect of the PETM, increased temperatures

tracked by using fossils which first appeared 55 million years ago during the Eocene (CCLE 2017). Horse morphology seemed to evolve throughout the time periods in response to their changing environments. This becomes evident upon comparing limb, teeth, and skull morphology of the fossilized remains throughout time. The morphology of the earliest horse, the Hyracotherium, reflects an environment characterized by the Eocene period: thick closed canopy forest environment. In general, the Hyracotherium

Abstract There is need for exploring new frontiers and production of hydrocarbon from the Niger Delta basin for use in the energy sector. Sequel to this, it is pertinent to have adequate knowledge about the geology the basin to discover and exploit new conventional sources. The geology of the Niger Delta basin is summarized into three depositional belts; Akata, Agbada and the Benin formation. The source rock for oil in the basin is from the Akata formation whilst Agbada formation is the main reservoir

omnivorous browsers (Hunt 4). Eohippus survived for about twenty million years with relatively few evolutionary changes (Wikipedia 7). These animals lived in a sub-tropical climate and ate soft fruits and the leaves of trees. During the middle to late Eocene and into the Oligocene epoch several other members of the equids, with distinct evolutionary changes, existed including the Orohippus, Epihippus, Mesohippus, and Miohippus. The Orohippus developed from the Hyracotherium and shared many of the same

alive, mammals were the ones occupying the earth. This specific period of geological time, called the Paleogene period, dated back to 66 million years ago and ended 24 million years ago; further dividing the Paleogene period, there is the Paleocene, Eocene, and Oligocene epochs. Each epoch is categorized based on their distinct differences, mainly in geography, climate, plants, and animals. To find out why scientists split the Paleogene into four epochs, we will analyze the differences in ecological

there are three periods: the Paleozoic, the Mesozoic and the Cenozoic. The very effective mammalian versatile radiation is altogether inside the latest period of topographical history, the Cenozoic. There are seven ages in the Cenozoic - Paleocene, Eocene, Oligocene, Miocene, Pliocene, Pleistocene and Holocene. In Paleocene (65 m.y.a.), the Lemuroids were the gathering of primates that existed. The Ruffed Lemur began in the tropical rainforests of Madagascar. They ate for the most part organic products

The current locations of the continents, inhabitants, including humans, existing today can be traced back to this period. The Cenozoic Era is divided into three periods. Paleogene Period (65-23 million years ago), which consists of the Paleocene, Eocene and Oligocene epochs); Neogene Period (23-2.6 million years ago), which includes the Miocene and Pliocene epochs); Quaternary Period (2.6 million years ago to the present), consisting the Pleistocene and Holocene epochs). The early part of the Cenozoic

The Onset of the Northern Hemisphere Glaciation By Christina Ohrazda Student at Stockholm University 28.09.15 Introduction The Northern Hemisphere Glaciation (NHG) is believed to have initiated into large scale, permanent ice sheets ~2.5 Ma, which is almost 31.5 Ma after the initiation of the Antarctica ice sheets. There are many possible causes for the onset of this climate event, some of which we will be reviewing in this essay. In this essay we will look at the cores from IODP and ODP sites 302
