were giants. Some dinosaurs were no bigger than small dogs. The smallest kind was about the size of a chicken. No human being has seen a living dinosaur but‚ scientists have many ways of learning about them. One important way is by studying fossils. Fossils give scientists a vast amount of information about ancient animal and plant life which have become extinct. They also helped them in finding out how long ago the animal or plant lived. As animals and plants die over the years they get covered

least 6 million years. A. From Ape To Man Fossils from several different early australopith species that lived between 4 million and 2 million years ago clearly show a variety of adaptations that mark the transition from ape to human. The very early period of this transition‚ prior to 4 million years ago‚ remains poorly documented in the fossil record‚ but those fossils that do exist show the most primitive combinations of ape and human features. Fossils reveal much about the physical build and activities

Uses of fossil fuel Fossil fuels consist of coal‚ petroleum and natural gas that are found under the earth’s surface‚ formed from billions of years of compression and decomposition of dead plant and animal matter. They are the leading source of energy for the mankind and are used for various purposes like energy for transportation‚ electricity‚ manufacturing process and also used in the manufacturing process of day to day items like plastic. Main fossil fuels are. 1. Coal Coal is

discussing about how were fossils found‚ techniques on finding fossils‚ and whether or not dinosaurs could have evolved to being warm blooded. Fossils are the preserved remains‚ or traces‚ of animals‚ plants‚ and other organisms left behind. Fossils are mostly found where sedimentary rocks of the right age are exposed‚ such as river valleys‚ cliffs‚ and hillsides. Paleontologists are scientists who studied fossils‚ collecting fossils from all over the world. The fossil record provides evidence

Earth History (Geological Timeline) Lecturer Dr. Sameh Abu El Soud History of Early Geology Catastro‐phism Tries to explain the presence of everything on earth and their composition by catastrophes. E.g. A catastrophe happened to dinosaurs 80 million years ago. A comet fell on earth surface leading to volcanoes‚ leading to dust clouds in the atmosphere‚ preventing solar rays penetration ‚ the plants died and then the dinosaurs. Uniformi‐tarianism (James Hu on‚ late 1700s) ‐ He proposed that the

determine the age of materials. We need to understand how fossils are made so we can date them properly. There are five ways bones are fossilized. They are by permineralization‚ unaltered preservation‚ carbonization‚ authigenic preservation‚ and recrystalization (Shepherd). When a fossil is found you need to make sure that it can be preserved properly so it can stay in the same shape to enable research. Many steps are taken to prepare fossils and conserve them. Hardeners are used to protect against

billions upon billions of fossils‚ we don’t have one fossil showing where one plant or animal for that has or had evolved into another. Even if the theory of evolution was proven to be true‚ then we would have billions times billions of "in between" animal forms one taxonomic group developing into another. We have none. Fossils Themselves Prove a Worldwide Flood The fossil records themselves indicate the earth is only a few thousand years old and that was a worldwide flood. Fossils are found all over

this activity you’ll make use of some of the techniques and evidence that paleontologists work with to determine the identity of different fossils to establish the particular time period in which those creatures lived. Most fossil digs take place in remote places where it is hot and dry and dirty. But one outstanding (and famous) site for Pleistocene fossils is right in the middle of downtown Los Angeles: The La Brea Tar Pits. Check out this site to learn about bones that have been preserved
