Table 3 in A new dentition-based phylogeny of Litopterna (Mammalia: Placentalia) and ' archaic' South American ungulates

Table 3. Divergence-time means for each tip-dated Bayesian analysis, and the total mean and total maximum and minimum ages across all the tip-dated Bayesian analyses.Abbreviations:CA, common ancestor; H1, hypothesis 1 for the notoungulate paraconid (see methods); H2, hypothesis 2 for the notoungulate paraconid (see methods); N, constraint in the node for the common ancestor of SANUs between the K/Pg boundary and the oldest age for the kollpaniids of Tiumpampa (66–65.075 Mya); top, topological constraint in the analysis to make the topology similar to the one in the undated Bayesian analysis (see Material and methods). Maximum and minimum ages were based in the 95% HPD of the same node in different analyses.
