This is the famous southern Chinese Liujiang skeleton.Consisting of a well-preserved skull and a few other bones, Liujiang was discovered in a small cave at Tongtianyan in the Guangxi Zhuang Autonomous Region in 1958 by people collecting fertilizer.
So, for the moment at least, Perak Man is the best local evidence that the older pebble tools encased in ash were made by the same (modern) human species.I have stuck my neck out to place modern humans in Malaysia by this date on the basis of the Kota Tampan site where tools were found under a thick layer of volcanic ash from Toba.The key tools were indisputably artefacts, and the ash did come straight from the sky 74,000 years ago.If that is so, it may provide the answer to one of the most nagging questions about the unifacial oval pebble tools: who made them?On the face of it, these are by no stretch of the imagination sophisticated tools.The dating of the earliest Flores (Eastern Indonesia) occupation by modern humans remains to be published.
I have several corroborating reasons for relying on such a connection.There is no doubt that this person was anatomically modern, but from the start there has been controversy over its age.A uranium date of 67,000 years was reported, but has been questioned on the basis of its exact location in relation to dated geological strata.For a start, the dates for most of the pebble tools found in the Lenggong Valley are too recent for them to have been made by anyone else.Second, no pre-modern humans have ever been found in the Malay Peninsula, let alone in the Lenggong Valley.Zuraina’s trump card in this respect is the much publicized finding by her team of ‘Perak Man’ in the Gunung Runtuh cave in the Lenggong Valley in 1990.
