Answer:
The challenges were
* the fossils cannot be dated
* only certain archaeologists permitted
* difficult working conditions
Explanation:
The Rising star Cave was located in South Africa. And in 2013, specifically in the month of October, under the tutelage of Lee Rogers Berger , who was a South African, Rick Hunter and Steve Tucker, were able to discovered the Dinaledi Chamber, which was located in the Rising Star Cave.
This chamber was found out to be containing several hominin fossils.
In summary, it was guessed that the hominin fossils discovered would have perhaps two million years ago or more.
This showed that the proposed age range for the fossils also overlaps with the early Middle Stone Age, fueling a provocative, though unproven, possibility: that the stone-tool record in South Africa from that time wasn’t just the handiwork of anatomically modern humans.
In this case, the challenges faced by the archaeologists were the ones given above.
