In reptiles, the 'nasal scale' refers to the scale that encloses the nostril.^[1]
Sometimes this scale is paired (divided). In such cases, the anterior half is referred to as the 'prenasal' and the posterior half is referred to as the 'postnasal'.^[2]
'Supranasal scales' are located above the nasal scale.
