The trace fossil Zoophycos is abundant in the shallow‐marine deposits (tempestites) of the Lower Devonian (Emsian) Yangmaba Formation in Ganxi of Sichuan, South China. It often occurs as part of complex trace fossils that comprise different integrated elements: scratch traces, simple to complex spreiten structures with marginal tubes (Zoophycos) and vertical tunnels.

1. Introduction. Zoophycos is among the most distinct trace fossils. As defined by Häntzschel (Reference Häntzschel and Teichert 1975), Zoophycos is a planar spreite marking successive, former positions of the burrow, present either as simple lobes or as ornate spiral structures, enclosed by a marginal burrow which may not always be evident (either not developed or not preserved).Semantic Scholar extracted view of "Zoophycos cyclicity during the last 425 ka in the northeastern South China Sea: Evidence for monsoon fluctuation at the Milankovitch scale" by F.
