Some human ancestors may have met their fate at the end of a beak and sharp talons, becoming bird food for prehistoric raptors, according to a study in the October issue of the American Journal of Physical Anthropology.

W. Scott McGraw, an anthropologist at Ohio State University, along with collaborators there and at the University of Liverpool in England, drew that conclusion after examining more than 600 bones of modern monkeys found beneath the nests of African crowned eagles in the rain forest in Ivory Coast.

Ancient Raptors Likely Feasted On Early Man, Study Suggests

Ohio State University (OSU): Columbus - A new study suggests that prehistoric birds of prey made meals out of some of our earliest human ancestors.

Researchers drew this conclusion after studying more than 600 bones from modern-day monkeys. They had collected the bones from beneath the nests of African crowned eagles in the Ivory Coast's Tai rainforest...

...Punctures and scratches on many of the monkey skulls have led some researchers to rethink which animals may have preyed on our human ancestors, said W. Scott McGraw, the study's lead author and an associate professor of anthropology at Ohio State University...

...Archaeologists discovered the skull of a 3 1/2 year old ape-like child in a cave in South Africa in 1924. Researchers believed this child, called the Taung child (Australopithecus africanus), had been killed by a predatory cat. But McGraw said that puncture marks on the monkey skulls he examined closely resemble those found on the skull of the Taung child...
