Work on fossil pollen by co-author Raymonde Bonnefille and others at the site has identified dozens of ancient species so far, none of which was also found on the savanna.
Work on fossil pollen by co-author Raymonde Bonnefille and others at the site has identified dozens of ancient species so far, none of which was also found on the savanna.
