The Tashwinat mummy was found in a cave of the archaeological site of Uan Muhuggiag in Libya. It is the mummified body of a child about threeyears old, buried there between 5,400 and 5,600 years ago. The mummy was wrapped in goatskin and its interior was filled with a mixture of herbs.

According to archaeological findings, the beginning of the Egyptian state dates back to 3000 BC, so this burial predates ancient Egypt by about half a millennium.

Wall paintings depicting people and animals were also found in the cave.
