Zoophycus
Trace fossils, including Zoophycus, Chondrites, and Planolites, have been identified in or just below the light-colored shale intervals (e.g., Lineback, 1968, 1970; Cluff, 1980).

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.Zoophycos appears to be the most common trace in this ichnofabric, associated with several other ichnotaxa (Fig. 14c). Generally, the ichnofossils in this ichnofabric, with higher abundance and moderate diversity, are mainly composed of trails on the bedding plane and a few fodinichnia near the bedding plane, locally crosscutting each other.The slope, terraces, and plateaux from depths of 200 to 2000 m are referred to as the bathyal or deep-sea zone. The bathyal zone and the abyssal and hadal zones below it are referred to as the deep sea. In much of the hydrocarbon resource area of the North West Shelf, the sea bed lies in this depth zone. Sediments of the North West Shelf slope ...Zoophycos from both regions is composed of a marginal tube and a tongue-like spreiten complex, the latter itself consisting of primary lamellae in planar view and backfill structures (dark and ...The first Zoophycos-bearing level (Zl 1) ranges from a wacke-to packstone texture with moderate benthonic skeletal fragments, resulting probably from storm events, deposited below fair-weather ...[Photo of Zoophycus trace fossil].

We studied it because the internal stratigraphy was well understood, and prior studies had examined the interbedded sandstones and the paleoecology of infaunal and epifaunal brachiopods.

Enter the email address you signed up with and we'll email you a reset link.A number of ichnotaxa do show changes in their relative abundance through the Phanerozoic, possibly indicating ecological competition or niche replacement (e.g. Early Palaeozoic Dictyodora replaced by Mesozoic and Cenozoic Zoophycos).

Multidisciplinary studies have allowed us to describe the abiotic landscapes and, thus, reveal the ichnological and benthic foraminifera trends in a deep-water gateway.
