Hanoi (VNA) – During the recent fieldsurvey in Ba Be National Park in the northeastern province of Bac Kan,archaeologists have found many traces of early humans in caves in karstmountains around Ba Be Lake.
The findings were announced by AssociateProfessor, Doctor Trinh Nang Chung from the Institute of Archaeology, VietnamAcademy of Social Sciences, on July 18.
Traces were found in Tham Kit Cave, Tham MyaCave, Na Phoong Cave, and Ba Cua Cave in Nam Mau commune, Ba Be district.
Most traces were uncovered inTham Kit Cave, which is 50m above the lake surface. The cave faces southwestwhile its inside measures nearly 3,000 square metres. Its floor is fairlysmooth and divided into three large rooms with many small corners. There aremany big stones inside the cave, which are believed to have fallen from thecave’s roof during big geological changes in the past.
Scientists discovered many carved tools fromstones, and one single layer of culture of 50cm thick formed by clay inside thecave containing ancient objects, bones and teeth of animals. They also foundmore than 50 stone objects and traces of an oven.
The bones and teeth of animals found in thesemi-fossilised form are believed to be remains of food left by early humans.
Particularly, excavators found a small flatpebble bar with two holes of some 1.2cm in diameter on the surface. The objectseemed to have been carefully carved and cut; however, its usage is still amystery.
Traces of semi-fossilised bones, teeth and stoneobjects showed that hunting and picking vegetables and fruits were fairlyimportant in how early humans sought food.
Chung confirmed that based on a generalexamination of objects, traces and sedimentary soil, scientists believe ThamKit Cave was a residential area of early humans in the late period of the oldStone Age, some 20,000 years ago.
Excavators have also found stone objects of HoaBinh Civilisation (12,000-10,000 BC) in nearby Tham Mya Cave and many ceramicobjects of the Metal Age in Na Phoong and Ba Cua caves./.
