Keller et al. pointed that crinoidal shoal deposits called Baleas Limestone are at least locally sandwiched into the Llombera beds. However, in a more distal setting, the Llonbera beds are replaced by muddy limestone and dark shales, which can be topped by crinoidal limestones of the Bales Limestone (van Loevezijn and Raven 2017). The DCB …

Crinoidal. Crinoidal limestone deposits found in Derbyshire, England were laid down during the Lower Carboniferous times prior to progradation of large deltas from the north, which formed the later Millstone Grits. At that time, the part of the UK that would become the English Peak District was the bed of a sub-tropical shallow continental shelf sea with ...

The Hume Limestone contains abundant macrofauna and is strongly crinoidal in some areas: It has produced a rich, high diversity conodont fauna typical of the Po. siluricus Zone. Taxa include Po siluricus, Oz. excavate, Oz. confluens and C. dubius. Many other species typical for this interval could be determined by a modern taxonomic treatment ...

A Gem of Crinoidal Limestone: This cabochon was cut from a piece of fossiliferous limestone that is rich in crinoid debris. Crinoids are organisms that have the morphology of stemmed plants but are actually animals. Rarely, crinoidal and other types of limestone have the ability to accept a bright polish and have interesting colors and patterns.Crinoidal Limestones – Limestones with a significant amount of crinoid fossils. Also known as sea lilies, Crinoids are marine echinoderms. Also known as sea lilies, Crinoids are marine echinoderms.

The living crinoids orders are: Millericrinida, Cyrtocrinida, Bourgueticrinida, and Isocrinida (all sea lilies); and Comatulida (feather stars). The class Crinoidea is the ancestor group of all other echinoderm classes. The relationships among extant orders are still obscure, but some attempts have been made to elucidate them. Crinoidal and coated grain pack- and grainstones make up the bulk of the sequence, interlayered with partially dolomitized mudstones and peloidal pack/grainstones. Mississippian reservoirs characteristically exhibit a high degree of vertical and lateral heterogeneity, which results from rapid lateral facies changes as well as a complex …Crinoidal limestone similar to the Belgian type is produced in for example Ireland, where it is known under the name of Irish Blue Limestone.
