Asterosoma . ludwigae is well known from the Carboniferous Atoka shale including Phycosiphon, Chondrites, Asterosoma, Rhizocorallium, and Zoophycos. These facies show a strong wave influence on deposition, but with persistent evidence of fluvial and possibly tidal conditions, reflected by abundant mud drapes attributed to fluid mud and/or flocculation of mud from buoyant (hypopycnal) plumes.

The mass of rock at the base of the outcrop broke free from where it formed and slid downhill to this location. After sliding (or tumbling) to its new location, sediment accumulated around the olistolith. Eventually, it and the sediment became a new rock .Natural fractures and discontinuities have significant impact on subsurface flow conditions and thus production, of carbonate reservoirs, particularly in low-permeability sediments such as chalk ... ….
