History of discovery

The archaeological significance of the Lenggong Valley began to emerge in the 1980s and 1990s through surveys and excavations led by Professor Zuraina Majid of Universiti Sains Malaysia, who became the principal excavator of the valley for over two decades. Her most dramatic find came in 1991, when she and her team excavated the cave of Gua Gunung Runtuh and recovered the near-complete skeleton of an adult male, aged approximately 40–45 years at death, in a foetal burial position accompanied by grave goods including a stone tool and food offerings. Radiocarbon dating placed the burial at approximately 10,000–11,000 BCE. Named the “Perak Man,” the skeleton is now one of the most important paleoanthropological specimens in Southeast Asia.

The chronological scale of human occupation at Lenggong expanded dramatically in 1995, when excavations at Bukit Bunuh uncovered stone tools and flakes embedded in a geological horizon of suevite — a rock type formed by the heat and pressure of a meteorite impact. The impact event has been dated by uranium-lead methods to approximately 1.83 million years ago, making the associated tools the oldest known evidence of hominin presence in Southeast Asia. The responsible hominin species has not been identified from skeletal material at Bukit Bunuh, but the tools are broadly comparable to the Oldowan and early Acheulean industries of Africa and western Asia.

Later excavations at Bukit Jawa and Gua Teluk Kelawar filled in the middle of the sequence, with Neolithic-period evidence of pottery production, polished stone tools, and evidence of a burial tradition extending across multiple millennia. The combined evidence from all four sites presents a picture of the Lenggong Valley as a place of continuous or repeated human occupation across an almost unbroken span of nearly two million years — a concentration of cultural and paleoanthropological evidence without parallel in Southeast Asia.
