Scientists believe that Dee died in an arroyo which has changed over time so that Dee was found on a hilltop. Why would that land feature have changed? Describe the process. (Land changes across time due to erosion. The arroyo changed into a hill due to windblown deposition) Why are more mammoth fossils found in the eastern plains than Wyoming? (Climate change- more wet so more grass.) How would scientists develop hypotheses regarding Dee’s death? (Geologists and paleontologists would look at Dee’s bones. For example: Tusk rings determine age, teeth erosion demonstrates the loss of chewing ability, bony ridges on vertebrae determines arthritis, thus difficulty moving with seasonal climates.) Online Resources: Students complete question sheet correctly and engage in group discussions regarding Dee Evaluation: the mammoth. Enrichment: Take students on field trip to the Casper College Tate Museum and see the Dee permanent exhibit.
