Sedimenttexturen und Lebensspuren der Sohlbank des Naturdenkmals „Saurierfährten Münchehagen“

The basal bed of the Natural Monument Münchehagen, called "Sohlbank", is composed of a quartzitic sandstone. The bed is characterized by wave ripple bedding, which is altered by biotrubation. Ist surface cuts erosively older, thin sandstone layers typically covered by riplle marks on their upper bedding plane. All ripple marks are oscillation ripples which are partially modified by retreating water. Sedimentary channel fillings cut into the “Sohlbank“. A highly diverse ichnofauna is described. It comprises elements of a Cruziana ichnocenosis in addition to some traces of a Skolithos ichnocenosis. The sedimentary and biogenic structures suggest a low energy, shallow-water depositional environment.
