Dating The Fossil Record Activity
From the information you have, are you able to tell exactly how old a certain fossil is? Why or why not? What information does relative dating provide to paleontologists? Part 2 You are planning to prepare a timeline for the paleontologist in California.
But when the results, shown below, come in from the geology lab, you discover that the dates have become separated from the appropriate rock samples. You have already determined the relative ages of the samples.
Dating the Fossil Record Investigation
All you have to do is arrange the dates from oldest to youngest. Fossil Ages The dates provided by the geology lab are as follows: You now have all the information you need to make a timeline for the paleontologist in California. Use colored markers or pencils and register tape to make your timeline. Draw a line with the dates labeled on the line with a metric ruler.
Let 1 centimeter equal 1 million years. Draw and label the fossils at the appropriate date. Based on the information in your timeline, what age range would you assign to each of your fossil species?
Measure from the year that a fossil first appeared in the rock record to the first year it was absent in the rock record. Fossil Species Age Range Globus slimius to million years old Fossil Species Circus bozoensis Age Range to million years old Microbius hairiensis to million years old Bogus biggus to million years old Fungus amongius to million years old Bananabana bobana to million years old 7.
Dating the Fossil Record Background Information: You have received nine rock samples from a paleontologist in California. Your job is to arrange the samples in order from oldest to youngest according to their fossil content and to determine their relative ages using the process of relative dating.
Results from absolute dating methods will not be available from a laboratory for several weeks, and the paleontologist needs the information immediately. You know from previous work that rocks of Sample 2 are the oldest.
Set of nine cards representing rock samples, pencil, colored pencils, and glue. After the fossil cards are cut out, arrange the fossil cards from oldest to youngest. Begin with Sample 2 because you know this sample is the oldest.
You may need to try several different arrangements to get the cards in order.
After an organism becomes extinct, it does not reappear in younger rocks. In the table below, record the samples in order from bottom to top oldest to youngest in the first column. Sample 2 is done for you. Identify the fossils with the fossil key, and write their names in order by age from left to right in the top row of the table.
Examine your fossil cards carefully to determine where each fossil appears in the rock record.
Write an X in the appropriate column to indicate which fossil or fossils are present in each sample. What would you conclude if there were an X outside the pattern? Based on the information in your table, which fossil is the youngest? From the information you have, are you able to tell exactly how old a certain fossil is?
