lenggong : suevite and 1.8 million years old ago....

bukit bunuh, lenggong ; axe and flake tools were found embedded in rock layers of suevite caused by the meteorite impact.

what so exceptional about it?

first, the meteorite impact was dated  more than 1.8 million years ago...the tunguska impact recorded in modern time dated in 1908 (affected 2,000 km square) had shown how devastated it can be.

tunguska..the aftermatch

second, the axe and flake tools proved the existence of human activity in this region that period...more than 1.8 million years ago!!

third, it can change the world history by reconsidering the 'out of africa theory'...with this discovery there was fresh evidence of human mobility coming from Asia and Southeast Asia, and not just out of Africa.....

Bukit Bunuh Site, Lenggong, Perak
1. Date found: August 2000
2. Site type: Open site
3. Location: Longitude (100° 58’ 05” E) and Latitude (5°04’05” N)
4. Early excavation:

From 2001 to 2003.
Excavation was undertaken in the southern area of Bukit Bunuh. Palaeolithic cultural layers in a form of a stone tool workshop were discovered. OSL (Optically Simulated Luminescence) dating method gave a date circa 40,000 years ago. Handaxe that was made out of suevite has also been discovered. Meteorite impact had caused the native stone to melt and formed a new stone called suevite. This impact has been substantiated by the presence of suevite, crossed- lamellar microstructure on quartz, physical anomaly evidence and geomorphology evidence of an impact crater. The distribution of suevite is approximately 3-4 km².

2000-2006 research contributions:
• Evidence of Palaeolithic culture, dated back to 40,000 years ago.
• New geological unit – suevite as an evidence of meteorite impact circa 1.74 – 1.83 million years ago.
• The discovery of in situ handaxe, with a chronometric dating of 40,000 years ago.

5. 2007-2008 Research:
• The discovery of stone tools artefacts such as handaxe and flake tools inside of suevite, suggesting that there was a human being in Bukit Bunuh area before meteorite impact, circa 1.74 – 1.83 years ago.
