Across 50 ancient Clovis sites in North America, archaeologists found a strange carbon-rich “black mat.” What’s fascinating? Extinct megafauna bones and Clovis tools lie beneath this layer.

Late Pleistocene North America supported a diverse guild of large-bodied animals, clinically defined as megafauna (species exceeding 44 kg / 97 lbs). Among them were the proboscideans—Woolly Mammoths (Mammuthus) and American Mastodons (Mammut); apex predators such as the Sabe
