From: Advantages of doubly polished thin sections for the study of microfossils in volcanic rock
Photos showing microfossils from opposite sides. An example of the advantages of using both sides of a thin section. A and B showing a tubular filament attached to volcanic glass from opposite sides. C and D showing a twisted filament where the same twisted features are shown from both sides indicating that it is a three-dimensional morphological feature. E and F showing a filament blocked by another filament. In E the whole filament is visible but in F parts of the filament is blocked. The scale bars are 10 μm.
