This collection is in the former. Smith's Gypidula-Atrypa-Schizophoria Community, which sits in zone 3 in his 6-zone onshore to offshore gradient, shallow to deep subtidal, below wave base.

• This part of section as a whole: "Unnamed carbonate unit (at least 500 m thick) which can be broken into three members. The lower member is coposed of thin-bedded argillaceous lime-mudstone containing common argillaceous seams and contains a varied brachiopod fauna as well as corals, gastropods and, in the upper parts, oncoloites....second member consisting of thin to med. bedded silty lime-mudstone containing common to abundant colonial corals as well as bryozoans. The third member is thin to very thin bedded, silty argillaceous lime mudstone containing in places lime mud intraclasts exhibiting sedimentary drape, channeling, as well as what appear to be small-scale ripple marks and common to abundant leperditiid ostracodes." This unit: "Argillaceous lime mudstone: thin bedded, undulatory; med. dk. grey to grey-brown,...well indurated, common yellow-grey argillaceous seams, other seams grey-green; few brachiopods, common colonial corals; slightly silty to sandy; some beds have fair amount of tiny comminuted debris..."
