The overlying Brattstad Member (upper 9e and 9f of Kiær 1908) is 30 m thick and consists of medium to thickly bedded limestones in its lower and upper parts, with interbedded marls and dolomitic limestones in the middle of the member (Fig. 19). The limestones contain a relatively rich and varied fauna; 1 to 3 m thick massive favositid and oncolitic biostromes (the 'Favosites Limestone' of Kiær 1908) are characteristic of the uppermost beds of the member. The basal stratotype of the member is defined in a coastal exposure at Brattstad (NM745670) at the first occurrence of massive lumpy bedded limestones which lie above marls with desiccation cracks assigned to the Sjørvoll Member.
