Alaska’s first elasmosaur fossil excavated The fascination with dinosaurs Since much about the early phase of the world is still much unknown‚ or at least mysterious‚ many are drawn to that particular era. Who wouldn’t‚ what with the exotic sea creatures and land creatures that lived in those times and would eventually become extinct or evolve to the animals of today? There are thousands of museums across the world featuring exhibits of these ancient creatures. One of those exhibits is in the University

and sells the shells that she finds. Mary Anning was a young woman born to a working class family that lived in Lyme Regis‚ a small seaside town in England. She grew up helping her father comb the beaches for fossils they would sell to tourists. Even after her father died‚ Mary kept up the fossil collecting practice in order to sustain her mother and brother. But what started out as a means of survival for the Annings turned out to impact the world of paleontology in the early 19th century‚ though Mary

Fossil Fuels Josh Farrar 11/16/13 The three types of fossil fuels that are used for energy provision are coal‚ oil‚ and natural gas. Fossil Fuels are the remains of once living organisms‚ but it takes centuries to form the organic matter. Coal is millions of years of decaying land vegetation (dead plants) that will form the solid fossil fuel under intense pressure. Oil is formed on the sea floor from the remains of marine microorganisms and is deposited

shallow‚ warm sea. This is indicated by the presence of Trilobite fossils found in this layer which thrived in that environment. Trilobites were early animals that had exoskeletons that are usually the only part of them that is preserved in the fossil record. They were marine bottom feeders who thrived in warm nutrient rich waters. The Redwall and Temple Butte limestone that compromises the next layer of rock and the marine fossils there indicate that the sea had deepened and given rise to a more

untrained eye‚ but to Charles Doolittle Walcott and other paleontologists‚ it is a treasure trove of thousands of uniquely preserved fossils. Millions of years ago‚ North America rested on the equator. Earth was still too young for terrestrial plants and animals to inhabit the hostile land; instead‚ they dwelled in the sea where a vast array of organisms thrived. The fossil records beautifully preserved in the shale rock‚ tell the story of the Cambrian Explosion‚ a period where organisms evolved at

THE WAR ON RELIGION The decade long War on Terror and Islamic Extremism has given rise to an aggressive and activist Atheist movement here at home. Islamic terrorist groups like Al Qaeda‚ Taliban‚ Islamic Jihad‚ Hamas‚ and others have apparently reinforced the atheistic belief that the problem is not terrorism‚ or even Islamic extremism‚ it is the belief in God and religion as a whole. Although‚ it should be noted that Atheist groups rarely openly attack Islam‚ which on the one hand‚ would not

Evolutionary relationship Diprotodontid fossils dates back 25 million years ago to the late Oligocene period. These animals were about the size of a sheep and were mostly likely descened from the wynyardiids. The subfamily Diprotodontinae‚ including Diprotodon optatum‚ are a Pliocene-Pleistocene

DISCUSSION QUESTIONS Chapter 1 - Finding Your Inner Fish 1. Explain why the author and his colleagues chose to focus on 375 million year old rocks in their search for fossils. Be sure to include the types of rocks and their location during their paleontology work in 2004. They chose to focus on 375 million year old rock because fish and amphibians found a few million years earlier‚ fish withou2t amphibian characteristics were found and a few million years later creatures with amphibian characteristics

recognized in the early 1800s that the fossil record had systematically changed through time.” This lead scientists‚ namely geologists from all over the world to make divisions of geological time known as a relative time scale. In order to get a generalized date they placed rocks and fossils into eras and periods. With a relative time scale‚ scientists were able to work together to establish a timeline they could use to categorize the age in which the rock or fossils existed. John Wesley Powell discovered

For example‚ I think he should have included references from other scientists‚ and mentioned specific research done on‚ for instance‚ fossil evidence. The truth is that my opinion on evolution is very much the contrary of Ian Johnston’s. To me‚ and to many other scientists‚ evolution is just a scientific theory- a very poor theory- that‚ when its own evidence is put together‚ gives a
