Question

A section of rock made up of layers of limestone and shale has been studied and samples have been taken. A large variety of fossils were collected from the rock samples. Use a sheet of graph paper to make a bar graph using the information shown in the Fossil Data Table. Begin by listing the types of fossils on the horizontal axis. Use Figure A to list the units of the geologic time scale on the vertical axis. Transfer the range data of each fossil onto your graph. Draw an X in each box, beginning at the oldest occurrence of the organism up to the youngest occurrence Shade in the marked boxes. You will end up with bars depicting the geologic ranges of each of the fossils listed. Examine your graph. Are there any time units that contain all of the fossils listed? Write this time period at the bottom of the graph.
