The document discusses sedimentology and bioturbation in cores, thin sections, and permeabilty maps from microporous nodular limestones. It includes definitions of terms like bioturbation, ichnofauna, diversity, and lithology. Observations are made of sediments including bioturbated mudstone, laminated mudstone, intensely bioturbated mudstone with moderate diversity, and cross-bedded sediments with variable bioturbation and moderate diversity, indicating environments from outer shelf to tidal channel to inner shelf.

“Those aspects of the sediment's texture and internal
structure that arise from bioturbation and bio-erosion at all
scales" (Ekdale & Bromley 1983).
“A record of the primary sedimentary conditions, original
animal community, and subsequent history of one or more
phases of biogenic activity” (Taylor & Goldring 1993).
