On the banks of the Danube near the town of Ryahovo in Bulgaria, the remains of an ancient mammoth have resurfaced. The river, with water levels at record lows because of recent heatwaves, has revealed bones which, according to researchers at the Regional History Museum in Ruse, belong to a specimen of 'Mammuthus primigenius', commonly known as the woolly mammoth. So far, researchers have identified and recovered a jawbone, tusks, a shoulder blade, ribs and other bone fragments, but much of the skeleton is probably still buried. RelatedWhat is emerging from the DanubeThe Danube, which flows through 10 countries from south-west Germany to the Black Sea, has dropped to record low levels along much of its course, exposing rocks, sandbanks and ancient wrecks that were rarely visible in the past. The discoveries are not the only consequence of the Danube running dry, though.
