“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).
