This presentation will be about the JCU-led efforts to date the Homo naledi fossils from the Dinaledi Chamber and the JCU involvement in the discovery of a second chamber in the Rising Star cave system, containing additional specimens of Homo naledi, including a child and a partial skeleton of an adult male with a remarkably well-preserved skull.   The new dates reveal a surprisingly young age for Homo naledi, between ~335-236 thousand years old. This was unexpected because the remains have primitive features that are shared with some of the earliest known fossil members of our genus, such as Homo rudolfensis and Homo habilis, species that lived nearly 2 million years ago. The age for the Dinaledi fossils shows that Homo naledi lived alongside other species of hominins in Africa, including early Homo sapiens.  In this talk, we will discuss the challenges associated with dating the fossils, implications of the discovery of a second fossil chamber, and the significance of this work for understanding human evolution.
