© Kesler Science, LLC INPUT STATION Read It! Imagine going for a walk in Yellowstone National Park. As you are observing your surroundings, you notice something interesting in the rocks. Read Part 1. Jot down notes and drawings that will help you remember the meanings of these words. You can use the sketch/scribble button on the toolbar. Fossils Part 1 What could these pictures in the rock mean? You feel the rock and notice that these are not drawings on top of the rock…they appear to be impressions of leaves and twigs in the rock itself. You ask a park ranger to explain what you see. He tells you these are fossils - the preserved remains of ancient organisms that once lived in this area. He also says that fossilization, the process through which a living thing becomes a fossil, is quite rare. This means that most living things do not end up becoming fossils. It takes millions of years for a living thing to become a fossil, and there are lots of different ways it can happen. fossils fossilization sediments Type/draw here. Type/draw here. Type/draw here.

© Kesler Science, LLC INPUT STATION Read It! The type of fossil you are examining is called a mold . This is when a living thing is pressed into rock, the living material decomposes, and an impression is left behind. If there had been small pieces of rock called sediments that filled these impressions in the rock, they could have cemented into another rock. The fossil formed would be called a cast . There is also a fossil type that does not actually show the body of an animal. In a trace fossil , an animal’s footprint, feces, trail, or burrow become fossilized. Examining these types of fossils helps us learn about an animal’s life. Fossils Part 2 As the park ranger finishes explaining how different types of fossils are formed, you look around the park and notice how much of the landscape was formed by erosion the gradual wearing away of rocks by wind, water, and other natural events. These tiny sediments gradually pile on top of dead animals and cement together over time, which is why most fossils are found in sedimentary rock . After all you’ve observed and learned today, you’re thankful for a beautiful park and all the wonders of the past that can be revealed through fossils! Read Part 2.
