   In a preliminary study the geographical occurrences and distribution of some rostroconch taxa of the order Conocardioida throughout the central / equatorial continents and oceans of four distinct diversity acmes in the middle Early Devonian, the late Middle Devonian, the late Early Carboniferous and the middle Late Carboniferous are shown. These middle and late Palaeozoic rostroconchs show distinct distribution patterns which enable a separation of provisional biogeographical provinces. During the middle Early Devonian, Conocardium attenuatum and C. nevadensis as well as Hippocardia cunea, are restricted to the south-western coast of Eaurussia (eastern North America), whereas Hippocardia bohemica, H. ornatissima, H. abrupta and Conocardium prunum are typical for the Bohemian Terrane. In the late Middle Devonian (and probably early Eate Devonian) Hippocardia cunea, H.
   monmica and Conocardium pseudobellum characterize west-central Eaurussia, Bigalea clathrata occurs at the south-central coast of Eaurussia (western / central Europe), Armorica and Bohemia, and Conocardium gogoense is restricted to Australia. By the closure of the Variscan Ocean in the late Early Carboniferous, a distinct separation of southern Eaurussia is visible in the restriction of Aphelacardia alternistriata, Hippocardia herricki and Baiosoma cucullata to south-western Eaurussia (eastern North America), whereas Conocardium alaeforme, C. elongatum, Hippocardia fusiforme and H. hibernica are confined to south-central Eaurussia (western / central Europe); some of which (Conocardium alaeforme, Hippocardia hibernica) may also have occurred at the south-eastern coast of Eaurussia (Russia, Ukraine). A separate realm existed at the western coast of Eaurussia, indicated by Arceodomus glabrata and A. prolata.
   After the closure of the Palaeo-Tethys, two separate realms persisted, characterized by Apotocardium lanterna and some minute hippocardiids in western Eaurussia and Conocardium orientate, C. ustritskyi and Arceodomus snjatkovi in eastern Eaurussia. The distribution maps also reveal particular information gaps which include Morocco, South America, South-East Asia, China and Australia but, although far beyond of being complete, our current data pool of conocardioids proves advanced rostroconchs to be important taxa for discriminating biogeographical provinces in the Middle and Eate Palaeozoic. Based on the continuous addition of data to our data base, the distribution maps will reveal improved and modified information
