An Example from the Middle Jurassic Protobatioladinium mercieri sp. nov. FEIST-BURKHARDT & PROSS 1999.
Light microscope images, descending focus series. Specimen in left lateral position, coloured by fuchsine.
|Extended focus image of the 16.8 Ám thick specimen, left lateral face. The image is composed of a stack of 50 single optical sections. Distance between single optical sections: 0.34 Ám. By applying the computer contrast mode SFP, enhancing opacity and adding an oblique light source a wrinkled thin outer membrane covering the cyst wall becomes visible.|
|After rotation of the image stack 180 ░ around the y-axis, one can see the hidden back side of the specimen (SFP mode).|
|Single optical section no. 16 of a total of 50 optical sections. Note the frothy porous structure of the cyst-wall, the presence of the thin outer membrane and the outline of the opercular pieces.|
|Single optical section no. 28 of a total of 50 optical sections. Note the homogenous thickness of the cyst-wall in optical section and the hollow apical horn.|
