Description of methods used for collection/generation of data: Cenozoic Angiosperm Database and published literature; GenBank; WorldClim database; Global Biodiversity Information Facility. 2. Methods for processing the data: We used the Coexistence Approach (CA) to estimate climate variables of fossil flora; We aligned all sequences using MAFFT v.7.308; We inferred phylogenetic trees of extant species using Maximum Likelihood (ML) for the partitioned and non-partitioned molecular data sets in raxmlGUI 2.0; We used total-evidence dating based on the non-partitioned molecular data set and morphological matrix to estimate a calibrated phylogenetic tree of extant and extinct species under the fossilized birth-death process in BEAST v.2.6.1; We used the Dispersal-Extinction-Cladogenesis model to infer geographical range evolution with three dispersal-constrained time slices in BioGeoBEARS; We calculated dispersal and extinction events from the BioGeoBEARS results; We estimated divergent evolutionary trajectories for latitudinal and climatic variables by using a new Time-variable Trend Brownian Motion model implemented in fossilBM (https://github.com/dsilvestro/fossilBM). 3. Instrument- or software-specific information needed to interpret the data: BioGeoBEARS; fossilBM.
