...Caroline J. Buttler; Mark A. Wilson Abstract A bryozoan-dominated fauna that inhabited small caves underneath a carbonate hardground is here described from the Corryville Formation (Upper Ordovician, Katian) exposed near Washington, Mason County, Kentucky, USA. The dominant bryozoan, Stigmatella...

...John H. Powell; Basem K. Moh’d ABSTRACT Hardgrounds and omission surfaces are rare in the predominantly pelagic and hemi-pelagic chalk, chert and phosphorite lithofacies association that forms the Upper Cretaceous (Coniacian to Maastrichtian) Belqa Group succession in central Jordan. However, newly...

.... This paleoecologic study examines a carbonate hardground surface encrusted with four species of isorophid edrioasteroids: Curvitriordo stecki , Carneyella ulrichi , Carneyella pilea , and Streptaster vorticellatus . Analysis of edrioasteroid diameters, a proxy for age, shows a bimodal distribution for Curvitriordo...

... to polygonal fractures in submarine pavements, with a similarly cursory mention of a couple of sentences in Shinn (1969) . Kendall and Skipwith (1969) do not cover polygonal buckling in marine hardgrounds at all. The point being that such fleeting mention is not tantamount to a defensible explanation...

... with encrusting Girvanella, eocrinoid plates, rhynchonelliformean brachiopod valves and subordinate hyoliths and trilobites in tempestite shell beds; these beds underwent synsedimentary cementation on the seafloor to form hardgrounds. In the succeeding, higher energy interval, a complex of metre-scale bioherms...

... of the Glossifungites ichnofacies from the floor of a submarine canyon channel, formed through the exhumation of a firm siltstone layer by erosive turbidity currents. Bromley and Allouc (1992) described borings in modern bathyal hardgrounds formed through surficial lithification of carbonate oozes. Erosion...

... basin succession. This 14 m interval is divisible into 13 small-scale cycles that are widely traceable and record a lithofacies gradient from calcarenite-rich outcrops of central Kentucky into interbedded fine-grained grainstones and organic-rich shale in the subsurface of western Ohio. Hardgrounds...

... biosphere. In Utah, borings were excavated in hardgrounds that had developed on sponge-algal mounds and flat-pebble conglomerates in the Fillmore Formation (Ibexian). The most complete specimens possess a neck up to 1 cm in length that opens into a teardrop-shaped chamber with a maximum diameter of 1 cm...

... complete specimens preserved in situ with the cupule-bearing side facing toward the bedding surface. Sedimentological, petrographic, and trace fossil evidence suggest that this bedding surface had the consistency of a hardground during the lifetime of the cyclocystoids. This provides the first unequivocal...

..., and hardgrounds (see Wilson and Palmer, 1992 ). The cylindro-clavate boring Palaeosabella has a similar habit. The Onniella epibole borings are not preserved in their full extent; hence we cannot determine whether they are Trypanites or Palaeosabella . The organisms that created these borings preferred...

Metre-scale cycles, like those reported from numerous other peritidal deposits, are apparently absent in this succession. In addition, these strata are commonly interrupted by a variety of hardgrounds. The carbonate strata...
