| Selected specimens were examined under the SEM, then embedded in resin and cut into 3 m thin sections using a rotation microtome. |
| With SEM, the light line was found to be where the secondary thickening bars were tightly appressed to each other. |
| Coverslips were then coated with gold and attached to an SEM stub with tape or rubber cement before SEM scanning. |
| Nine of 25 damaged fusulinids were mounted onto SEM stubs for preparation of scanning electron micrographs. |
| A quick, qualitative analysis of valves during SEM work confirmed the presence of pyrite and the calcium phosphate composition of the carapace. |
| We prepared the filters for SEM analysis by sputtering a thin gold film on them. |
