#TurbiditeTuesday fabulous calc-turbidites of the South Shore Formation at Whitehouse shore, Girvan. Late-Ordovician. Part of the Laurentian margin sequence, when Scotland was part of North America, Canada and Greenland. These rocks contain typically North American fossil assemblages, quite distinct from the European assemblages found in rocks of the same age in England and Wales. #BoumaSequences #IapetusOcean
