Several types of markings are described and illustrated which occur on the lower surface of graded gray-wackes in beds alternating with shales and occurring in thick "resedimented" sequences (Flysch, Kulm, Macigno, and similar coarse, deep-water, marine basin fillings). An attempt is made to explain their origin in deep water and to classify them accordingly as (1) precurrent markings, (A) tracks, (B) burrows, (C) excrements, (D) current ripple mark; (2) current markings, (A) flute casts (= flow marks), (B) gouge channels, (C) drag marks; (3) depositional markings, (A) slide marks (together with the drag marks they form the groove casts), (B) load casts and load-casted earlier markings; (4) postdepositional markings, (A) entrapment burrows, (B) turbidite burrows; (5) miscellaneous markings of unknown origin. Most of these markings have been reported from other environments also, but their combination in great profusion is claimed to be unique for resedimented rock series.
