AB Cretaceous charophytes and Palaeocene larger foraminifera are facies-linked microfossils used to performbiostratigraphic correlation between distant basins, in Eurasia (charophytes) or the whole Tethys (largerforaminifera). The capability of these organisms for dispersal and colonization is analysed and appears tobe dependent both on palaeoecological and palaeobiological factors. During the Cretaceous of the Northernhemisphere, Clavatoracean charophytes include five cosmopolitan or subcosmopolitan species. They displaya generalistic range of habitats (from fluvial siliciclastic to alkaline lacustrine and brackish) and conjointgametangia (monoecious) allowing them to colonize effectively new sites and disperse. Palaeocene Tethyanlarger foraminifera that show a large distribution live in the deeper parts of shallow platforms, a habitatwhere the taxonomic diversity within the group is low. Significant for the long range geographic expansionof larger foraminifera is the possibility to catch planktonic algae to establish the species-specificendosymbiosis that characterize the group. In spite of being so different, both case-studies suggest thatthere are common patterns of biogeographic behaviour of this kind of facies-linked microfossils, whichcould lead to propose a model of biogeographic constraints in long distance biostratigraphic correlation
