Fig. 17. Evolutionary events supporting the marine and geodispersal dispersal hypotheses to explain the distributions of Arapaima and Heterotis. Each dispersal hypothesis requires four main evolutionary events (that are mapped on time calibrated phylogenetic trees and a 60 Ma paleomap reconstruction). Paleomap modified from Seton et al. (2012). Timescale in million years ago (Ma). For each hypothesis, possible ancestral areas at nodes shown on phylogenies (Abbreviations: Afr, Africa (Afrotropics); Sam, South America (Neotropics); NA, North America (Nearctics); Eur, West Eurasia (West Palearctics); EA, East Atlantic; WA, West Atlantic. "X" means extinction). Grey rectangles indicated time limit for each hypothesis.
