World’s Oldest Animal Drawing, Discovered in Borneo Cave, Is a Weird Cow Beast
A 40,000-year-old painting of a mysterious, wild cow-like beast discovered in a Borneo cave is the oldest human-made drawing of an animal on record, a new study finds.
The discovery indicates that figurative cave art — one of the most significant innovations in human culture — didn’t begin in Europe as many scientists thought, but rather in Southeast Asia during the last ice age, the researchers said.
Drawing animals, an accomplishment in itself, may have been a gateway for illustrating other aspects of the human experience, including hunting and dance. “Initially, humans made figurative painting of large animals and they later start depicting the human world,” said study co-lead researcher Maxime Aubert, an archaeologist and geochemist at Griffith University in Australia.
The ancient artwork covers the walls of secluded limestone caves in the rugged and remote mountains of the East Kalimantan province of Indonesian Borneo. Researchers have known about these human-made drawings since 1994, but they didn’t know when the illustrations were created until now, said Aubert, who worked with Indonesia’s National Research Centre for Archaeology (ARKENAS) and the Bandung Institute of Technology (ITB).
The researchers collected calcium-carbonate samples from the Kalimantan cave drawings so they could do uranium-series dating — a technique made possible by radioactive decay. When rainwater seeps through limestone, it dissolves a small amount of uranium, Aubert told Live Science. As uranium (a radioactive element) decays, it turns into the element thorium. By studying the ratio of uranium to thorium in the calcium carbonate (limestone) that is coating the cave art, researchers determined how old the initial coating was, he said.
The oldest figurative art — the mystery animal that is likely a species of wild cattle that once stomped around the jungles of Borneo — was at least 40,000 years old, Aubert said. Previously, the oldest known animal painting in the world was an approximately 35,400-year-old babirusa, or “pig-deer,” on the Indonesian island of Sulawesi, he said.
Artwork through the ages
The team’s results showed that the ancient artwork in East Kalimantan was made during three distinct periods. The first phase, which dates to between 52,000 and 40,000 years ago, includes hand stencils and reddish-orange ochre-drawn animals — mostly the banteng (Bos javanicus), a type of wild cattle that still lives in Borneo, and the mysterious, unknown wild cow, Aubert said.
A major change happened to the culture during the icy Last Glacial Maximum about 20,000 years ago, which led to a new style of rock art — one that focused on the human world. The artists in this phase favored a dark mulberry-purple color and painted hand stencils, abstract signs and human-like figures wearing elaborate headdresses and engaging in various activities, such as hunting or ritualistic dancing, the researchers said.
“We don’t know if these [different types of cave art] are from two different groups of humans, or if it represents the evolution of a particular culture,” Aubert said. “We are planning archaeological excavation in those caves in order to find more information about these unknown artists.”
The final phase of rock art includes humanlike figures, boats and geometric designs that were mostly drawn with black pigments, the researchers said. This type of art is found elsewhere in Indonesia and may come from Asian Neolithic farmers who moved into the region about 4,000 years ago, or more recently, the researchers said.
