The two lower specimens are popular khyung thokchas, dating to the early Buddhist period. Horns aside, their general form is reflected in rock art raptors. The probable pre-Buddhist upper specimen, with its pyramidal head and abstract aspect, somewhat resembles the dark red raptor pictograph (6c). Despite exhibiting far fewer details than the khyung thokchas, this amulet has a strong and vibrant outline, a defining trait of analogous Upper Tibetan rock art motifs as well.
