Occurrence of the Lower Cambrian anemone-style trace fossils in the Zabuk Formation (Mardin–Derik, SE Turkey)

摘要

The Zabuk Formation of the Derik Group exposed over much of south-eastern Turkey presents a succession composed of shallow marine and fluvial siliciclastic sedimentary rocks. The Lower Cambrian assemblages containing abundant anemone-style trace fossils are known from most major palaeocontinents such as Laurentia, Baltica, and Gondwana. These have possible affinities with semi-infaunal dwelling anemones on siliciclastic mid-latitude shelves of West Gondwana in early Fortunian deposits. Among them isBergaueria, characterized by plug-shaped burrows as exemplified byBergaueria?perata, that is, a characteristic trace fossil of the Cambrian globally.
