"Drought uncovers ancient rock carvings resembling emojis along the Amazon River"
Ancient rock carvings, estimated to be between 1,000 and 2,000 years old, have been revealed on the shores of the Rio Negro in the Amazon region due to an unprecedented drought. The petroglyphs, including human faces, animals, and tool sharpening marks, were previously sighted during a severe drought in 2010 but have re-emerged this month as water levels dropped further. Fragments of ceramics dating back thousands of years have also been found at the site, which was home to large Indigenous villages in pre-Columbian times. The petroglyphs have not been studied extensively, but researchers are estimating their age based on similar carvings in other parts of the central Amazonia region.
