  • The Importance Of Existance Of Lake Malawi

    active volcanism while ash was washed away from the basin and deposited at the bottom of the lake (Crossley, 1984). Maturation is important for hydrocarbon existence and is enhanced by heat which occurs during extrusion and intrusion processes. The heat mobilises and moves hydrocarbons making the igneous rocks present potential reservoirs or source rocks. Reservoirs and seals with hydrocarbon potential in most cases are found in the syn-rift successions, in Lake Malawi there are also in form of deltaic sandstones present in the margins of the lake(Scholz, 1995). Sequence of Karoo sediment has been determined in the lake with the possibility of being the source rock or reservoir, succeeded by post Karoo Mesozoic reservoir rock and capped by Miocene. The sediments thickness in the northern part is greater than 2 km with the bottom of the lake revealing organic sediments in highly anoxic conditions. Despite similarities in the overall stratigraphy in the half graben basins each is filled differently and source rock in each half graben is determined once its drilled (Crossley, 1984). 2.5. Previous Work 2.5.1. Structure and Stratigraphy Lake Malawi exhibits unique structural and architectural characteristics due to faulting process. Series of faults are present with major faults trending from northwest to Southeast for example Livingstone fault as shown in figure 2.2 and figure 2.5 while others trend west-east. Extensional faults dipping in eastward direction in the…

  • Ardipithecus Anthropology

    million years ago, the dietetic capabilities of the most primitive beings shifted intensely. This left Ardipithecus in a better condition for life in for all kinds’ habitats and with the ability able to survive with major changes in resource obtainability linked with climatic fluctuations (Teaford 2000). The tooth shapes, particularly are ways to observe alterations in the internal properties of foods, for example their durability and deformability. However the cranial fragments of the…

  • Gray Wolf Evolution

    of the gray wolf had similar features to the Miacidae it lived from the Ypresian to the “Bartonian of the Eocene.” The were around 20 to 30 centimetres long and had five claws. The Miacis had forty four teeth unlike modern day adaptations that have around 30 teeth but the Miacis were smaller in size. The Miacis had “low skulls, long slender bodies, long tails, and short legs” as well as “retractable claws, agile joints for climbing, and binocular vision.” The Earliest forms of a wolf were much…

  • Megalodon Research Paper

    My extinct animal is the megalodon. Not only was the megalodon the biggest prehistoric shark that ever lived,it was the largest marine predator in the history of the planet, vastly outweighing both the modern Great White Shark and ancient reptiles like Liopleurodon and Kronosaurus. Megalodon had a diet befitting an apex predator, feasting on the prehistoric whales that swam the earth's oceans during the Pliocene and Miocene epochs, but also chowing down on dolphins, squids, fish, and even giant…

  • Ardipithecus Ramidus Summary

    Reading Response to White et al.: Ardipithecus ramidus and the Paleobiology of Early Hominids. In the article, Ardipithecus ramidus and the Paleobiology of Early Hominids, by Tim D. White et al. , the Ardipithecus ramidus specimen ARA-VP-6/500 from the Aramis vertebrate paleontology locality 1 (ARA-VP-1) expedition is examined in depth. The ARA-VP-1 is located in the Middle Awash and expands into the Central Awash Complex (CAC) with different localities, numbered from 1 up. The Middle Awash…

  • Possible Connections Between Mountain Building And Global Climate Change

    Introduction Mountain building is a process that takes place slowly on a geological timescale. It is, therefore necessary, in order to explore the role mountain building plays in global climate change to examine past epochs where the full impacts of these processes may be evaluated. One period in which evidence for possible connections between mountain building and global climate change is particularly rich is during the Oligocene-Miocene transition. As such, this essay focuses on the…

  • Aegyptopithecus Essay

    Modern day primates like the Howler Monkey closely resemble the ancient Aegyptopithecus primate. Howler Monkeys known for their loud howls that can reach up to three miles away plus enjoy making nests to live in while Aegyptopithecus are known for bridging the gap between the Eocene and Miocene fossils. The Aegyptopithecus and the Howler Monkey have numerous similarities and differences. The differences include geographic location, skeletal features, and daily behavior; meanwhile similarities…

  • Megaladon Teeth Research Paper

    Abundance of Fossilized Megalodon Teeth Washing Ashore in North Carolina The shores of North Carolina are known for having Megaladon teeth, but they are currently experiencing a bumper crop. Beachcombers in North Carolina are finding much more than just seashells recently because there has been an influx of fossilized Megaladon teeth washing up on the beaches and it has paleontologists excited. Megaladon Ruled the Ancient Sea Just for few moments, imagine a city bus, now imagine that bus with…

  • Parrot And Scarlet Macaws

    date to about 23–20 mya and are also from Europe. Subsequently, the fossil record — again, mainly from Europe — consists of bones clearly recognizable as belonging to parrots of modern type. The Southern Hemisphere does not have nearly as rich a fossil record for the period of interest as the Northern, and contains no known parrot-like remains earlier than the early to middle Miocene, around 20 mya. At this point, however, is found the first unambiguous parrot fossil (as opposed to a parrot-like…

  • Evolution Of Primates

    and we continue to show our ability to climb trees fairly well, however the main feature that has distinguished humans from modern primates has been our ability to walk on both legs, maintaining a sense of natural balance, of which primates lack. Ramapithecines had a center of gravity, which allowed them to walk on both legs, as we do now. “Of all the modern primates, humans are the only species that is truly bipedal” (MacDonald, 2003, p.330). Besides our physical forms, our ability to use and…
