The study of the partially preserved skull and several other bones showed that the ancient hominid possessed the features of a modern man — a high spherical vault of the skull and a characteristic chin. Scientists assumed that it was about 200 thousand years old, but this dating was considered not entirely accurate. Prehistoric bones were found in an area of high volcanic activity, so scientists tried to date volcanic ash in the layers from which the remains were extracted. However, radiometric methods worked inaccurately because the ash was too fine-grained. In a new study, scientists have been trying for about 4 years to date
