Thalassinoides typically forms boxwork systems and networks and has visible short vertical shafts on bedding surfaces, with specimens being smooth, lack-ing wall reinforcements and mainly consisting of horizontal-branched burrows (Fig. 4). The diameter of Thalassinoides varies little, commonly being in the range of 3–10mm, with some reaching ...

Deltaic depositional facies result from interacting dynamics processes (wave energy, tidal regime, currents, climate, etc.), which modify and disperse riverborne ( fluvial) clastic deposits.
