This activity encompasses two lab exercises. In the first lab exercise students examine various different types of microfossils (conodonts, foraminifera and radiolaria) under the microscope and try to make paleobiological inferences about them based on their morphological characteristics. Students also pick different conodont elements and different foraminiferal species from sediment samples. Two foraminiferal specimens are selected for scanning electron microscopy. I mount the specimens to a stub for the students. Then in the next lab period students are given a guided tour of the SEM lab and work with the technician to operate the SEM and take photographs of their specimens. They then use the photographs in conjunction with the Treastise of Invertebrate Paleontology to make a generic identification of their specimens.
