Prehistoric art is one of the earliest ways in which early humans transmitted messages. Geoglyphs are believed to represent important beliefs in ancient cultures. With respect to Andean cultures, however, colonization often erased evidence of traditions, hindering interpretation.
In February 2023, the largest known geoglyph depicting a felid was discovered in in the Atacama Desert in northern Chile. This geoglyph is located at a site known as Cerro Unitas, an important ceremonial site that includes the so-called Atacama giant, an anthropomorphic geoglyph (Briones & Alvarez, 1984, Estudios Atacameños, 7, 296–305). First recorded in a drone video, the felid geoglyph most likely re-emerged as a result of the removal of sand by strong winds. A preliminary assessment dates the site to c. 500 B.C. The geoglyph has a total length of 62 m from the head to the termination of the tail. For comparison, the so-called Nazca cat geoglyph discovered in Peru in 2020 is 37 m long.
The characteristics of the geoglyph suggest that it represents the Endangered Andean cat Leopardus jacobita rather than either of the other sympatric felid species in northern Chile (the puma Puma concolor and Pampas cat Leopardus colocolo). The long, broad, wide-ringed and uniform tail that does not taper towards the end differentiates the Andean cat from the Pampas cat, and the body shape and proportions, especially the legs and width of the tail, and spots on the flank, differentiate it from the Puma.
In the Andean worldview, the Andean cat has a role related to fertility and water, typically rainfall. Various modern ceremonies performed with desiccated but otherwise whole Andean cats decorated with brightly dyed llama wool are still performed in all four range countries of the Andean cat (Argentina, Bolivia, Chile and Peru), to ensure favourable harvests. The lines emanating from the head and forelegs of the Andean cat geoglyph probably depict the mediator between heaven and earth through the water and rain.
Although the subject of numerous research projects and despite threat reduction actions throughout its range, the Andean cat remains threatened. Our discovery connects the species to ancient sacred beliefs that endure today, and reinforces the importance of the Andean cat for ancient but persistent Andean cultures and of conservation action to ensure it remains extant for future generations.
