    • ‘In the study of fossil populations, the timing of encrustation is important, although both encrustation during life or after death provides ecological and taphonomic data.’
    • ‘Slight variations in the diameter along the length of some filaments reflect either the degree of silica encrustation or septa in the original filament.’
    • ‘Pollutants in the atmosphere and the attentions of birds and humans cause discolouration, encrustation and corrosion.’
