Late Ordovician and early Silurian virgianid and stricklandioid brachiopods from North Greenland: implications for a warm-water faunal province onlinelibrary.wiley.com/doi/… @ProfDATHarper @ICS2022 @datadryad @wileyearthspace
Top left: map of Greenland with the fossil outcrops of Upper Ordovician and lower Silurian strata shaded in the north. Bottom, schematic of the stratigraphy of the shallow-water sediments showing the the various localities (numbered) placed according to their approximate geographical position along the ~750km transect line, west to east (left to right). In the upper right quadrant, five examples of significant taxa from this fauna: top row - Tcherskidium tenuicostatum (GGU 254729) and Borealoides balderi (MGUH 34240, holotype); bottom row - Proconchidium schleyi (MGUH 34049), Virgiana hursti (MGUH 34226, holotype) and Kulumbella heimdali (MGUH 34259, holotype). All scale bars represent 10 mm.
