Ice sheets were not for- med on the African continent though there were substantial enlargements of the gla- ciers on many of the high mountains in Africa.

A drop in temperature and decreased precipitation would have had wide ranging effects on the vegetation of Africa. The forests which are so dependent on precipita- tion, often well spaced during the year would have suffered and would have demini-.
