Figure 1.

Simplified time tree of Cupressaceae estimated from the combined cpDNA + nDNA dataset, using a partitioned Beast analysis and calibrated using lognormal priors. Terminal branches and circles (indicating fossils) are coloured by geographical occurrence, as in the key. Fossils used to calibrate the Beast analysis are numbered as in Supporting Information Table S3 and Fig. S3. Fossil 10 (‘Callitris octothamna’) is at the position (node F) preferred by Bayes Factors. Fossil 11 (Libocedrus mesibovii) could be a Pilgerodendron (see text). Broad grey vertical bars show events in the breakup of Pangaea and Gondwana, graded from commencement to cessation of rifting. Black horizontal bars at nodes A to E show the 95% HPD of estimated divergence times (Table 2) between extant taxa in now‐separated parts of Laurasia and/or Gondwana. Dotted lines show gaps between these HPDs and the rifting event that putatively caused vicariance (B, D and E). Node G is the crown of Callitris s.l. The complete tree is shown in Fig. S11. Ma, million yr ago.
