The volcanic boulders in Toro Muerto that have petroglyphs carved into them vary in size, from small stones to enormous rocks coated in multiple images.
In the paper, the researchers propose that the geometric designs at Toro Muerto, carved alongside the danzantes figures, could symbolize songs or wild dancing.
Furthering this theory, it's suggested that certain intricate arrangements of danzantes and linear geometric patterns might serve as visual metaphors for passage to the afterlife.
"Our interpretation suggests that the banded structures of geometric patterns could be representations of the cosmos—its spheres and events connected to its creation and its exploration, which could have come about during ritual ceremonies of which dance and song were the quintessence," the paper's authors wrote.
"The scene on boulder TM 1219 indeed presents surprising similarities to the Tukano drawings, in terms not only of individual motifs but also their arrangement," the researchers wrote.
They further hypothesize that the scenes depicted alongside the dancing figures represent attempts to capture the sensations of music experienced while influenced by some form of hallucinogen.
