Optical Properties

The distal shield is in constant extinction because the optic axis (c-axis) is perpendicular to the microscope stage, whereas the proximal shield and tube cycle exhibit interference colours with inclined extinction.

Remarks

The elliptical placolith consists of a distal plate composed of non-imbricated segments, a proximal shield, and a tube cycle that supports an axial cross decorated with a hollow distal process.
