Eleven million years ago, the smallest known great ape that weighed just 10 kgs, lived in its full glory. The tiny great ape is far smaller than any other great ape on record.
The species, called Buronius manfredschmidi, is an ancient hominid. It is part of the ancestral family that gave rise to modern humans, gorillas and chimpanzees.
“This new genus is far smaller than any living or any fossil hominid,” Professor Madelaine Böhme, a palaeontologist at the University of Tübingen, who led the research, was quoted as saying by The Guardian.
“That makes it quite unusual.”
Human toddler-sized great ape: What did they look like?
Researchers found that the newly discovered species coexisted with much larger hominid, called Danuvius guggenmosi.

Fossil remains of the larger ape had previously been dated to the same period at the same fossil site in the German region of Bavaria. The new miniature ape has partial remains of two teeth and one kneecap. Their shape and size suggest that the smallest apes were adept climbers. The thin enamel and light wear on its teeth point out it ate a diet of soft fruits and leaves. Its small size would have allowed it to live high up in the canopy.
The findings are published in the journal Plos One.
Coexisting with larger Danuvius
Contrastingly, Danuvius was much taller and sturdier. They are thought to be both plant and meat-eaters.
The differences in lifestyle are likely to have allowed the two species to share a habitat without competing for resources much like modern gibbons and orangutans in Borneo and Sumatra.
What does it mean?
The discovery could help scientists understand the diversity of hominids during the late Miocene epoch (about 23.03 to 5.333 million years ago).
“It’s hard to say why there are no small hominids living today,” Böhme said. “In evolutionary lineages you normally start small and get bigger, and [once you’re bigger] you don’t normally go back.”
