crinoidal limestone or ‘petit granit’. The crinoidal limestone and the Tournai limestone are of Tournaisian age (c. 350 Ma); the Namur stone is slightly younger (Visean, c. 340 Ma). Over the years, there has been a shift in the prevailing type of limestone brought to the Netherlands. It is obvious that theThe Lower Cieszyn Limestone crinoidal assemblage is dominated by isocrinids (Isocrinida). This probably reflects the much shallower sedimentary environment of these sediments compared to that of the Upper Cieszyn Limestone, where excepting isocrinids, hemicrinids (Hemicrinidae, Cyrtocrinida) typical for deep marine environments were found.Crinoidal dolomite Peat /.

Silurian pelmatozoan echinoderms evolved a diverse suite of attachment structures that were used to occupy laterally continuous hardgrounds, isolated hard substrata such as shells and cobbles, relatively coarse and rubbly bioclastic sediments such as crinoidal gravels, and muddy to sandy softground substrates (e.g., Brett, 1981, 1984, …
