Figure 2

Chronogram of rodent diversification. Divergence times are calculated from the reduced-concatenated dataset using a relaxed molecular clock with four constrained nodes numbered 1 to 4 (see text for details) and represented by stars. Estimated dates with the 95% credibility intervals are represented by grey boxes at nodes. Time scale is indicated in Million of years below the figure. The zygomasseteric condition (H: Hystricomorphy; M: Myomorphy; S: Sciuromorphy; P: Protogomorphy) of each rodent family is specified on the right.
