Undersampling Taxa Will Underestimate Molecular Divergence Dates: An Example from the South American Lizard Clade Liolaemini

Table 3

Mean divergence time estimates in MYA for higher-level Liolaemini lizard clades for subsampling set 3 (deletion of taxa from subgenus Liolaemus) with all ten internal calibration fossils. Clade names correspond to names in Figure 1. SD is standard deviation as calculated in r8s1.8.
