Fossil recording is the way paleontologists can determine the relative and absolute age of fossils and rock layers. They use index fossils to help date the layers, with the Law of Superpositionwhich states that the oldest layers are the furthest down, with the youngest layer being on the top. This is because as new sediments are deposited, they push the older layers down.
Index fossils are fossil that are found in many places but only lived a fairly short period of time. You have been sent 9 samples from different layers of rock. You and your partner must study the fossils in the samples and determine the age of the layers using relative dating.
Record dating information takes longer to process, and the paleontologist who sent you the samples needs the data immediately! MS-LS Analyze and interpret data for patterns in the fossil record that document the existence, diversity, extinction, and change of life forms throughout the history of life on Earth under the assumption that natural laws operate today as in dating past.
MS-LS Apply scientific ideas to construct an explanation for the anatomical similarities and difference among modern organisms and between modern and fossil organisms to infer answers relationships. I can analyze fossil data and use observations to make inferences about how life has evolved. Finally, the results from the absolute age testing arrive! What can you do? You know the relative ages of the samples from the previous work. All you have to do is match the sample to the absolute age you were sent. In the data table, copy the sample numbers you dated by the Law of Superposition.
Put the ages the order as well. Then in the final column, write the names of all the samples that were found in that layer. Here are the dates.
