IMAGEDrought-hit Danube gives way to mammoth fossil hunt in BulgariaAs drought in Europe brings river levels to record lows, a group of volunteers scans the dried-up Danube riverbank in northern Bulgaria, not far from where the receding waters revealed mammoth bones in July. About 20 volunteers join an effort in the hope of discovering new fossils or artifacts in a search organised by the Regional Museum of History of Ruse.
