Facies analysis suggests that the early–mid Ashgill (Late Ordovician) ‘Boda event’ of Fortey and Cocks [Fortey, R.A., Cocks, L.R.M., 2005. Late Ordovician global warming—The Boda event. Geology 33 (5), 405–408] was an episode of global cooling, not of warming as they proposed. Limestones are widely developed at this level from mid-latitude to high-latitude, commonly interrupting thick Ordovician successions of fine clastic sediments. Bryozoan carbonate mud mounds in a laterally extensive cool-water carbonate belt along the high palaeolatitude margin of W Gondwana are associated with glacial diamictites, and grew during glacial lowstand with sea ice prior to the Hirnantian glaciation. From high to mid-palaeolatitudes, contemporaneous cool-wa...
