摘要: A huge wetland (the ‘Pebas system’) covered western Amazonia during the Miocene, hosting a highly diverse and endemic aquatic fauna. One of most contentious issues concerns existence, potential pathways effects marine incursions on this ecosystem. Palaeontological evidences (body fossils) are rare. The finding new, presumably ostracod species (Pellucistoma curupira sp. nov.) in upper middle Miocene Solimoes Formation initiated taxonomic, ecological biogeographical review genus Pellucistoma. We demonstrate that (sublittoral, euhaline), subtropical–tropical taxon is biogeographically confined to Americas. distribution Pellucistoma largely depends geographical, thermal osmotic barriers (e.g. land bridges, deep and/or cold waters, sea currents, salinity). assume an Oligocene/early Caribbean origin for outline dispersal hitherto known up Holocene. sp...
