Fossils indicate marine dispersal in osteoglossid fishes, a classic example of continental vicariance

The separation of closely-related terrestrial or freshwater species by vast marine barriers represents a biogeographic riddle. Such cases can provide evidence for vicariance, a process whereby ancient geological events like continental rifting divided ancestral geographic ranges. With an evolutionary history extending tens of millions of years, freshwater ecology, and distribution encompassing widely separated southern landmasses, osteoglossid bonytongue fishes are a textbook case of vicariance attributed to Mesozoic fragmentation of the Gondwanan supercontinent. Largely overlooked fossils complicate the clean narrative invoked for extant species by recording occurrences on additional continents and in marine settings. Here we present a new total-evidence hypothesis for bonytongue fishes combined with quantitative models of range evolution and show that the last common ancestor of extant osteoglossids was likely marine, and that the group colonized freshwater settings at least four time..., , , # Fossil evidence for marine dispersal in osteoglossid fishes, a classic example of continental vicariance
