Colorado State Anthropologist Finds Fossil Treasures In Africa

The vast collection of fossils is one of the few uncovered in Botswana and contains well-preserved specimens of small mammals that may have roamed the earth sometime between 100,000 and 3 million years ago. Most likely used by owls and other mammals to eat their prey, the cave is so rich with fossils it's called Bone Cave.
Waddle and the other researchers believe the find can help fill the gap in the fossil record of Botswana, an area that has not been a major focus for anthropologists or archaeologists in recent years. Although there are numerous sites containing stone tools in Botswana, the only human or primate remains from Botswana are less than 10,000 years old and are fully modern. Other fossils found in Botswana have been from the Middle Stone Age, roughly 100,000 years and earlier.
"This is a great find because of the wealth of fossils in the cave," Waddle said. "It's particularly important because Botswana has virtually no fossil sites of this kind and there really is no fossil record of primates at all. Many fossil sites may only produce a few fossils.
