An unusually rich and diverse suite of virgianid brachiopods, hitherto poorly known, is systematically described here for the first time from the Ordovician–Silurian boundary interval (late Katian – Aeronian) of North Greenland. The Late Ordovician virgianids comprise typical taxa of the warm‐water Tcherskidium fauna (e.g. Tcherskidium tenuicostatum, Proconchidium schleyi, Holorhynchus giganteus and Deloprosopus dawesi sp. nov.). Among the early Silurian taxa, Virgiana hursti sp. nov. occurs as abundant shell beds, similar to other congeneric species in Laurentia, but has somewhat larger internal skeletal structures, albeit not as extravagantly developed as in the late Katian virgianids; Borealoides balderi gen. et sp. nov. shows extreme thickening of the shell wall and internal structures, approaching the extravagant calcification of Katian virgianids. The highly distinctive mid‐Aeronian stricklandioid brachiopod genus, Kulumbella, characterized by a shell with criss‐cross (divaricate) ribbing, also occurs in North Greenland, represented by K. heimdali sp. nov., which has the largest and most strongly biconvex shells for the genus. Palaeogeographically, the Late Ordovician virgianid fauna of Laurentia was highly distinct, confined to the low–mid tropical latitudes north of the palaeoequator. In comparison, the early Silurian (Rhuddanian) Virgiana and some related taxa in Laurentia spanned the tropics of both hemispheres, forming extensive shell beds in carbonate basins, although Borealis and Borealoides gen. nov. remained confined largely to the northern hemisphere, suggesting a certain level of provincialism extending into the earliest Silurian. A palaeoecological preference for warm‐water carbonate settings would explain the unusual abundance and richness of the virgianid faunas in North Greenland.

“…Greenland is the largest of the world's islands, exposing Ordovician rocks around its margins in North Greenland and northern East Greenland; loose blocks containing Ordovician fossils are also recorded from the craton of West Greenland. Stouge et al (2023) have described in detail successions from western North Greenland (Franklinian Basin), eastern North Greenland (the north-eastern corner of Laurentia) and northern East Greenland (part of the Caledonian platform of northern Europe and the Appalachians). Greenland occupied a subtropical to tropical position during the Ordovician with faunas typical of Laurentia.…”

The Ordovician was a key period in the history of the Earth. “A Global Synthesis of the Ordovician System” is presented in two volumes of the Geological Society Special Publications series. The first volume (SP 532) covers general aspects of the Ordovician and includes the syntheses of the Ordovician successions of Europe. To provide a comprehensive global overview, this second volume (SP 533) represents a journey through the Ordovician System around the World. Reviews of the Ordovician of North America include syntheses of Alaska, Greenland, Canada, the USA and Mexico, whereas the South American Ordovician is summarized in a specific chapter related to Argentina and neighbouring countries. The Ordovician System of Africa is presented in chapters covering the North and the South of the continent where significant Ordovician successions occur. Australia and New Zealand, as well as Antarctica, are visited in separate chapters. Asia provides the most complex Ordovician successions reviewed in chapters covering Turkey and the Levant region, the Middle East, Central Asia, Kazakhstan, India, South-East Asia, China, Korea, and Japan. Our journey covers a great number of locations, but with many successions still to be fully described, the knowledge of the Ordovician of the World remains incomplete.
