Crinoidal.

The glauconite-rich sandstone passes upwards to a tidal crinoidal limestone showing oblique stratification and flaser structures. The second one, the Ponthoud Bed (S8, Figs. 4, 8d–e), is a 1 m thick green coquina-rich limestone, which is composed by a quartz and phosphate-rich packstone (Fig. 8e).Kimmswick is a high-calcium limestone (coarse, crinoidal grainstone) whereas Galena is a fine- to medium-grained, argillaceous, cherty dolomite. Lithology of the Kimmswick in Jonesboro area is same as at its type area in Missouri and cannot be readily divided into smaller units.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.Age: Early and Middle Mississippian Period. Distribution: Northern Arkansas, Ozark Plateaus; southwestern Missouri and eastern Oklahoma. Geology: The Boone Formation consists of gray, fine- to coarse-grained fossiliferous limestone interbedded with chert. Some sections may be predominantly limestone or chert. Crinoidal Marble Tumble Approx 2cm Crinoidal Marble is the marble remnant from a sea floor that contains fossil crinoids and other fossils.

They are an ancient fossil group that first appeared in the seas of the mid Cambrian, about 300 million years before dinosaurs. They flourished in the Palaeozoic and Mesozoic eras and some survive to the present day.

These crinoidal limestones and the associated shales contain same fauna as type Tichenor and the 10 feet of shale below. It is proposed to unite the 10 feet of shale with the 1 foot crinoidal bed at Tichenor Point, under the name Tichenor, and to apply this name to these limestones and associated shales as far west as Lake Erie.The Dunham classification system for carbonate sedimentary rocks was originally devised by Robert J. Dunham in 1962, [1] and subsequently modified by Embry and Klovan in 1971 [2] to include coarse-grained limestones and sediments that had been organically bound at the time of deposition. The modified Dunham Classification has subsequently ...
