Expedition Underway to Extract Latest Fossil Find From Cradle of Humankind Cave

Six specialised archaeological cavers in SA to help with new excavation

An international team of researchers will in the next few days begin excavations on a new site that may contain evidence of early human fossil remains in the Cradle of Humankind World Heritage Site (COHWHS), some 40km north Johannesburg.

Professor Lee Berger, a Research Professor in Human Evolution from the Evolutionary Studies Institute at the University of the Witwatersrand and a National Geographic Explorer-in-Residence, will direct the expedition at Rising Star Cave. Berger is best known for the discovery of Australopithecus sediba at the Malapa site in the COHWHS — one of the most significant palaeoanthropological discoveries in recent times.

The latest discovery was made by an expedition team sent out by Berger to search the deepest recesses of the caves in the Cradle. “The exploration team leader Pedro Boshoff and his two assistants, Steve Tucker and Rick Hunter, were able to access a chamber deep underground that is nearly impossible to get to, where they have found some significant fossils on the surface of the cave floor,” says Berger. The first step in the Rising Star Expedition is to get the fossils out of the cave and to study them thoroughly before any pronouncement can be made.

“We do not know as yet what species of hominin we have found, and we will not speculate. Our aim is to get the fossils out carefully, study them, compare them to other fossil material from around the world and then proceed to analyse and describe them. This is part of the scientific process and we are hoping to publish our findings — if all goes well — late in 2014,” explains Berger.

The key challenge is that the new site is in the cave structure of the Cradle and is about 30 metres underground, with a choke point only 18 cm wide.

This compelled Berger to call on his community of Facebook, Twitter and LinkedIn friends to help him find “tiny and small, specialised cavers and spelunkers with excellent archaeological, palaeontological and excavation skills.”

Within days Berger had a list of 57 qualified candidates, of which six scientists were selected to participate in the excavation, all of them women.

“These are highly trained scientists with caving experience from the US, Canada and Australia who are currently in South Africa preparing for the excavation,” adds Berger. “Only a limited number of people will be allowed to the access-restricted site, as one of my key priorities is the safety of our scientists and researchers. We also have to do the best that we can under the circumstances to get these fossils out of the cave, through a complex recovery process.”
