The fossilized remains of Homo sapiens idaltu were discovered in 1997 by Tim White at Herto Bouri near the Middle Awash site of Ethiopia’s Afar Triangle. Dating took place by the radioisotope method which analysed the volcanic layers containing the 3 cranial fossils [White 2003].
The morphology of the skulls display archaic features not found in the later Homo sapiens, but are still seen as the direct ancestors of modern Homo sapiens sapiens.
The remains discovered at Herto Bouri have been named 'Herto Man'. Experts claim the finds are complete enough to be identified as early modern humans, since they show the characteristic globular shape of the braincase and the facial features of our species. However, both the adult skulls are huge and robust, and also show resemblances to more primitive African fossils.
