Fig. 10

Variation of the mean keel angle in the upper keel region (Φ 1, in degrees) through time (in Ma) at Hole 925B for G. menardii (a), G. limbata (b), and G. multicamerata (c). In d means of Φ 1 are plotted together for better comparison (with ±95 % confidence intervals). Refer to Fig. 4 for explanation of parameters. For explanation of symbols see Fig. 5. Data and statistics can be read from Tables 4a–c and 6a–c in the electronic supplementary materials
