Europe's severe heat and drought have caused rivers to reach record low levels, uncovering previously submerged relics. In northern Bulgaria, the Danube River's decreased water level has exposed the remains of what is thought to be an ancient mammoth. The discovery includes a lower jaw, two tusks, and possibly a rib.

These bones will be tested to confirm the find. Further details about these discoveries can be found through news sources such as CNN, which has reported on the effects of Europe's heat and drought on its rivers, including the Danube.
