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

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

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

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

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

Fossil Fuels: Oil Introduction History We are a country that runs on oil. From the gasoline in our cars to the plastic in our computers to the detergents that we put in our dishwashers‚ we rely on oil for our modern way of life. It cannot be understated just how strong of a role it plays in our economy and politics. It is used in tractors that plow and harvest food. It is used to power manufacturing plants and as feedstock in commercial goods. It powers all the trains and trucks that bring goods

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

She is nicknamed ‘Selam’ after the Amharic (Ethiopia’s official language) word for ‘peace‚’ and is the most complete early human child known up until Neanderthal times. Prior to Selam’s discovery‚ researchers knew very little about early human growth patterns as the early human fossil record consists of few children. Because Selam’s baby teeth erupted in a pattern
