Detailed biostratigraphic and sedimentologic studies and recent discoveries adjoining the Horseshoe Atoll have documented the deposition of in-situ and associated intraclastic limestone reservoirs deposited in former slope and basin locations concomittant with periods of sea level lowstand. Our data suggest that the deposition of such reservoirs occur ed throughout the Late Pennsylvanian and

The material of the type species of Knoetschkesuchus, K. langenbergensis, comes from a marly limestone bed (numbered as Bed 83, not Bed 93 as reported by some publications) containing recrystallized micritic intraclasts, located within the Langenberg Quarry in the Harz Mountains near Goslar, Lower Saxony, Germany.

Moreover, the base of this unit shows a sharp lithologic change from the rippled calcarenites and intraclastic limestones of the underlying Poland into rather homogeneous shaly-nodular fine-grained calcilutite limestones.

lime mudstone: a limestone composed almost entirely of lime mud (micrite) and less than 10% grains (ooids, peloids, bioclasts, or intraclasts). Note that a lime mudstone is a carbonate rock. A rock composed of siliciclastic mud but with carbonate cement should be treated as one of the fine-grained siliciclastic rocks ("shale", claystone, mudstone, siltstone).
