									Fossil Project Instructions

Name__________________

Situation: The school has been given a collection of fossils that were gathered by a private collector, Mr. F.O. Sils. Mr. Sils got all of the fossils from different layers of rock that showed in a canyon on his property. The school has been given a diagram that shows what the layers of rock look like, and boxes of fossils. The fossils have been identified for general type, but many of the labels that show which layer of rock each fossil came from have been lost. Your job is to determine which layer of rock each fossil could have come from, what the landscape would have been like when each rock layer was laid down, and to create a guide that will explain your findings for this collection. Procedure: 1. Use the diagram for the rock layers in the canyon that this collection came from. Some of the layers are labeled for the rock type, and some have been dated through radiometric dating. These are known from the site. 2. There are boxes of fossil samples. Each box is labeled for the general type of fossil. Some of the fossils are labeled for the specific type of specimen (ex: cow instead of just vertebrate). The specific type of specimen name will help you with better dating of when that specimen was alive. 3. You need to determine the following: a. The relative age of each layer of rock in the canyon wall. b. When each fossil sample lived and the specific type of fossil. c. What type of environment each fossil sample lived in using the guide books. d. Which layer of rock in the canyon each fossil sample could have existed in. Some fossils could have been found together in some layers. Some layers of rock may not have had any fossils in them. There are disconformities in the rock layers. 4. Create a guide book for this collection. Make sure that the following items are in your guide book: a. Title page b. Table of contents c. Diagram of the canyon wall with each layer labeled with a letter for reference in the rest of the guidebook. You also need to create a key for the rock types in the diagram and to label each layer for the time period you determined for it. d. A written description of each type of fossil in the collection to accompany a drawing of the fossil. Included with this should be a reference to the layer of rock the fossil would be found in and why you placed it in this particular layer. e. A history of the land that now forms the canyon wall that starts with the oldest layer of rock in the canyon and proceeds to the present. This history should include a description of what the land looked like and the type of life to be found on it during the formation of each layer. It needs to include the type of rock and time period of formation. This history also needs to include what caused the unconformities and other changes to the layers of rock (ex: faults from earthquakes, volcanic activity, etc). This history may be in a timeline or narrative. There should be a drawing of what the landscape looked like for each layer. f. References. Include the books you use as resources in bibliographic format. Include a paragraph that gives credit to Mr. F. O. Sils for this collection.
