Comment:
a Amount of C4 material in sediments (%); Calculation based on d13C31.
b Amount of C4 material (%) contributed to sediments according to scenarios in this Table.
Postulated scenarios explaining abundance of C4 plant material in sediments based on river discharge and wind trajectories (Dupont and Wyputta, 2003) and map of proportion (%) of continental vegetation using the C4 pathway (Still and Powell, 2010; Fig. 4).
