Petroglyph

The UNESCO listing mentions “Konkan geoglyphs.” 

However, elsewhere, the term petroglyph (literally, “rock symbol/character”) is also used. 

As per the UNESCO listing, petroglyphs and geoglyphs share similarities as both require the skills of removing parts or engraving a symbol on the rock surface.

Petroglyphs are drawn by removing part of a rock surface by incising, picking, carving or abrading.
