Zoophycos is a complex burrow with stacked tiers, in which the tiers are made of spreiten-adorned lobes that radiate outward from a central tube in a downward spiral to form a shape that looks something like a Christmas tree in three-dimensions. Each lobe contains a peripheral tube, with spreiten loops between the tubes.Zoophycos is an ichnogenus thought to be produced by feeding worms.

It is known from …Trace fossils can be assigned to five associations from nearshore to offshore environments (namely Skolithos, Diplocraterion, Altichnus, Palaeophycus, and Zoophycos associations). They clearly illustrate the different colonization phases of the benthos with increasing marine influence.Nov 30, 2015 · Zoophycos is a characteristic trace fossil in the Mississippian in the Alborz Basin deposits of north Iran, and is described for the first time in the Mobarak Formation. The vertical distribution ... The distribution of trace fossils was influenced by lithology, sedimentation rate, energy level (storm events), bottom oxygenation, and nutrient supply. The lithofacies and trace fossils of the Chefar El Ahmar Formation both indicate a depositional environment fluctuating from the lower shoreface to lower offshore zone.The paleoenvironment influences trace-making behavior significantly, and progressively more evidence shows that this behavior follows scale-invariance properties. In this study, we focused on the definition of behavioral complexity in the trace fossil Zoophycos to explore its paleoenvironmentalSeilacher's Trace Fossil Analysis is designed to foster interpretative skills using the author's own iconic drawings.
