I Can… Compare fossils found in rock to determine their relative age. TOC #8 Find-a-saurus Activity

FINDASAURUS ACTIVITY Scenario: A paleontologist from Tennessee went on vacation to Montana where he discovered dinosaur bones in a particular layer of rock. He wondered if the same layer existed in Tennessee so he could find bones closer to home. If that particular rock appears on Earth’s surface, continuously, all the way from Montana to Tennessee he would be able to walk along the layer to follow it. That would be easy, but unfortunately, the easy way never seems to work. Erosion would make it impossible to follow the layer all the way from Montana to Tennessee. One of the most reliable ways to locate fossils is with other fossils. Index fossils can be used to track a layer from Montana to Tennessee, or from Montana to France. Relative dating places events in sequence within the rock layers while the process of determining if layers in different places are the same is called correlation.   I can compare fossils found in sedimentary rock to determine their relative age.

FINDASAURUS ACTIVITY 1. There are two stacks of rock layers, one in Montana and one in France. Your job is to determine: Which layers in Montana correlate with layers in France by matching the letters. Which layer in France contains the same dinosaur fossil as layer “d” in Montana.   2. Draw the fossils in the layers shown on the chart. For example, index fossil #2 should be drawn only in layers c and i. Make your best effort at reproducing the drawing.   3. Using colored pencils connect the borders of the rock layers in Montana with those in France. On the bottom of your paper: 2-minute journal reflection using accountable talk ( I hypothesize that ...) on which layer is correct and what you learned today. I can compare fossils found in sedimentary rock to determine their relative age.
