"Drought in Amazon Reveals Ancient Emoji-Like Carvings"
Ancient rock carvings, believed to be 1,000 to 2,000 years old, have been exposed along the Amazon River due to record low water levels caused by a severe drought. The carvings, including human faces and grooves thought to be used for sharpening weapons, were first discovered in 2010 but have become more visible this year. Archaeologists hope that the newfound variety of carvings will provide insights into their origins and the precolonial history of the region.
