    "West African sediments additionally record the African Humid Period, an interval, between 16,000 and 6,000 years ago, when Africa was much wetter because of a strengthening of the African monsoon by changes in summer radiation resulting from long-term variations in the Earth's orbit around the sun. The "Green Sahara" was dotted with numerous lakes containing typical African lake crocodile and hippopotamus fauna. A curious discovery from the marine sediments is that the transitions into and out of the wet period occurred within decades, not the previously-thought extended periods."
