Results for Spanomera mauldinensis from angiosperm‐wide molecular backbone analyses using maximum parsimony, based on 25 floral characters that could be scored for this fossil. The color coding, the time scale superimposed on the circular chronogram, and the sources of the backbone tree and morphological data set of extant taxa are as in Figure 1. The drawing in the lower right shows a female and a male flower of S. mauldinensis (reproduced from Friis et al., 2006, with permission of Elsevier). The position of the Gunnerales and Buxales is indicated by an orange bar in the circular chronogram. The pink circle indicates the approximate age of S. mauldinensis according to Drinnan et al. (1991).
