Death from Above
Were our ancestors hunted by giant birds? The answer appears to be "yes":
Afarensis: Anthropology, Evolution and Science: Was Australopithecus africanus Hunted By Birds?: According to this story the answer is yes:
A South African anthropologist said Thursday his research into the death nearly 2 million years ago of an ape-man shows human ancestors were hunted by birds. "These types of discoveries give us real insight into the past lives of these human ancestors, the world they lived in and the things they feared," Lee Berger, a paleo-anthropologist at Johannesburg's University of Witwatersrand, said as he presented his conclusions about a mystery that has been debated since the remains of the possible human ancestor known as the Taung child were discovered in 1924.
The Ohio State study determined that eagles would swoop down, pierce monkey skulls with their thumb-like back talons, then hover while their prey died before returning to tear at the skull. Examination of thousands of monkey remains produced a pattern of damage done by birds, including holes and ragged cuts in the shallow bones behind the eye sockets.
Berger went back to the Taung skull, and found traces of the ragged cuts behind the eye sockets. He said none of the researchers who had for decades been debating how the child died had noticed the eye socket damage before.
The study will be published in the AJPA...
