The geographical distribution of rostroconch taxa of the orders Ribeirioida and Conocardiida, mostly across the equatorial continents and oceans, is compiled for six presumed diversity acmes in the early Early Ordovician (c. 485 Ma), the late Early–early Middle Ordovician (c. 475 Ma), the Late Ordovician (c. 455 Ma), the Early Silurian (c. 435 Ma), the late Early–early Late Silurian (c. 425 Ma) and the early Early Devonian (c. 415 Ma), based on our present, uneven knowledge. Rostroconchs show distribution patterns which enable a provisional separation of biogeographical provinces at least from the Silurian...
