Lavoué Biogeography of the Asian and Australian arowanas 3 Journal of Biogeography Supporting Information Text S1 The three additional fossils used in all reconstructions to calibrate internal nodes are: (1) †Yanbiania wangqingica, dated to the Barremian age (129.4–125.0 Ma) (Zhang, 2004; Wilson & Murray, 2008) that is the oldest fossil unambiguously assigned to the crown-group Osteoglossomorpha (Li & Wilson, 1996; Wilson & Murray, 2008). †Yanbiania wangqingica calibrates the age of the crown-group Osteoglossomorpha to a minimum of 125.0 Ma; (2) †Palaeonotopterus greenwoodi from the Cenomanian stage (100.5–93.6 Ma) is considered to be the most ancient representative of the crown group (Notopteridae, Mormyroidea) (Forey, 1997; Taverne, 2000; Cavin & Forey, 2001; Hilton, 2003). I used this fossil to provide a minimum age (93.6 Ma) for the most recent common ancestor (MRCA) of the clade (Notopteridae, Mormyroidea); and (3) the minimum time divergence between Heterotis and Arapaima may be constrained to Late Palaeocene because of an undescribed basioccipital complex from Bolivia which is ‘decidedly Arapaima-like’ (citation from Forey & Hilton, 2010). I used this fossil to constrain the time of the MRCA of the crown-group Arapaiminae to a minimum of 61.6 Ma. REFERENCES Cavin, L. & Forey, P.L.

Figure S2 Bayesian time-calibrated phylogenetic trees under the O72R251 fossil calibration strategies using the complete matrix 1 (panel A) and the matrix 1 that excluded saturated partitions (panel B). Phylogenetic informativeness profiles of each partition in each matrix are shown above to the corresponding tree. In both trees, the age of the root is constraint to a minimum of 251.2 Ma while the age of the crown group Osteoglossidae is constraint to a minimum of 113 Ma. Calibration constraints follow exponential distributions. Elops hawaiensis is used to root the trees. Horizontal timescale is in millions of years ago (Ma). 95% age credibility intervals are shown as black horizontal bars (focal node of interest), and grey horizontal bars (all other nodes). All posterior probability support values at nodes equal 1 except for the Scleropages node in reconstruction B which is equal to 0.96. The effective age prior on the age of Scleropages is shown in (c), for each time-tree reconstruction. Timing of possible freshwater route between Sundaland and Australia–New Guinea predating the separation between India and Antarctica–Australia is depicted by light orange background with a minimum at 115 Ma.
